KENNA PERFECT Inserts – Cast Iron

Grade KC9325™

Grade KC9325 is ideally suited for machining gray irons and low-strength ductile irons (<45 ksi).Crater wear is the primary wear mechanism when machining gray irons at high speeds. Grade KC9325combats crater wear with a very thick Al2O3 layer. The grade’s unique combination of toughness andspeed capability make it a first choice for gray iron machining up to 1300 sfm.

Grade KC9315™

Grade KC9315 is the first choice for machining ductile irons. The thick medium-temperature CVD TiCN layer combats flank wear, which is the usual failure mechanism when machining ductile irons with a tensile strength of 50 ksi and greater. Use geometries ..MA, MG-UN, and MG-RP.

MG-RP Geometry The -RP geometry is available in a wide variety of grades and can be used to reduce cutting forces onunstable cuts or where work holding is not optimal. This is particularly advantageous when machininghigh-strength ductile irons (≥ 80 ksi). Reduced forces lower the temperature at the cutting interface, pro-viding long, predictable tool life.

Grade KC9110™

Grade KC9110 is an excellent choice for interrupted cutting conditions where grades KC9315 andKC9325 are not tough enough. Its unique combination of speed capability and outstanding toughnessmakes it an excellent choice for heavily interrupted cuts. Use MG-RN geometry as a first choice.

Wiper Inserts Wiper inserts are an excellent choice for straight OD, ID, and facing cuts. Feed rates can be doubled,reducing machining time by 50% while maintaining the surface finish. Insert nose radius has no effect onfinish since the wiper radius generates the final finish. Wiper inserts typically last longer since the work isspread over a longer cutting edge.

KENNA PERFECT Inserts – Cast Iron

Top Notch® Turning System for CeramicsWhen cutting with ceramics at high speeds, it is important to maximize the rigidity of the insert and toolholder. The Top Notch tooling system used in tandem with grades KY3500, KY1310, and KY3400“dimple” inserts provides ultimate rigidity for cast iron applications.

Grade KY1310™ (available January 2004)Kyon 1310 is designed specifically to maximize tool life in dry, continuous gray cast iron applications.Although not as tough as KY3500, KY1310 possesses good toughness at a high hardness level to optimize abrasive wear properties. Use KY1310 for continuous cutting in tandem with KY3500 for moresevere gray cast iron cutting applications to maximize tool life and minimize costs.

Insert Failure AnalysisCheck the insert thoroughly for signs of failure. To optimize your metalcutting process, remove insertsfrom the toolholder and inspect regularly for wear. Signs of chipping, deformation, built-up edge, cratering, flank wear, and thermal cracking are very evident in the early stages of wear but are almostimpossible to detect after total insert failure.

Boring with Wiper InsertsWhen boring with wiper inserts, chatter may increase due to the large wiper radii. To offset this lateraltool pressure, decrease the nose radius and increase the depth of cut. Remember that the nose radiusof a wiper insert doesn’t affect surface finish.

Grade KY3500™

Kyon 3500 is your first-choice ceramic cutting tool for tough gray cast iron applications, especially thosewith interruptions and scale. KY3500 is the most dependable ceramic grade for harsh gray cast ironapplications, and can be run wet or dry.

New Cutting Tool Technologies

Grade KC9315

During the last 20 years, dramatic improvementshave been made in turning insert performancethrough the development of innovative coatingmaterials such as aluminum oxide (Al2O3) andmedium-temperature titanium carbonitride (MT-TiCN). In recent years, cutting tool materialshave advanced even further through improvementsin coating interface adhesion, which can providethicker and more complex coating layers. This inno-vative processing produces smoother, less reactivecoating surfaces that resist edge build up,microchipping, and chip hammering.

Coating Systems

The thickness and number of layers of coatings on an insert typically have been limited to ensurethe integrity and stability of the coating. A coatingthickness of 10 to 14 microns typically was thelimit, which is significantly less than the optimumvalue. New technologies now make it possible toincrease both the number and thickness of the layers by providing high-strength interface transition zones that increase the adhesionbetween the coatings.

We employ this new technology on our new 18-micron coating system for grade KC9315.In conjunction with a hard deformation-resistantsubstrate, KC9315 is designed especially for high-performance machining of ductile irons andhigh-strength steels.

This new coating consists of three main layers.The bottom layer is titanium carbonitride to protectagainst flank wear – a major failure mechanism inductile iron and steel turning. This layer is appliedin a medium-temperature chemical vapor depositioncoating process that reduces the mismatch in thermal contraction rates during cooling to providefewer coating cracks and a tougher cutting edge.The middle layer is fine-grained alpha crystal structure alumina that protects against the elevatedtemperatures encountered in high-speed cuttingand provides an abrasion-resistant, chemically inert

barrier. The alpha crystal structure is more stablethan the more common kappa structure andimproves the coating resistance to failure. The top layer is a 2-micron titanium nitride/titanium carbonitride layer that provides additional wearresistance and serves as a wear indicator.

Grade KC9315 has an improved post-coating surface treatment that contributes to increased toolperformance. Polishing the outer coating surface toa higher-than-normal degree minimizes the poten-tial for built-up edge. In particular, the surfacetreatment removes the outer TiN / TiCN coatingfrom the tool-chip interface zone to further reducethe possibility of built-up edge.

The net advantage is the ability to run at higherspeeds and feeds relative to existing coated materials without suffering a reduction in tool life.KC9315 is an excellent performer at finishing tomedium machining at the elevated speeds requiredto be competitive when machining cast iron.

Grade KC9325

Kennametal’s reengineered KC9325 grade uses a coating technology similar to KC9315 and isdesigned specifically to maximize performance in gray cast irons. This coating features an extrathick top layer of fine alpha alumina to maximizeresistance to crater wear. An under layer of medium-temperature titanium carbonitride providesexcellent resistance to flank wear. A tough, deformation-resistant substrate is designed to work together with this new coating to maximizeresistance to crater wear.

The application range of KC9325 is expanded with improved performance in medium to heavymachining of both ductile irons and steels.

Silicon nitride-based ceramicsare the predominant ceramictools used for cast ironmachining, particularly graycast irons. These tools excel incast iron applications becauseof a unique combination

hardness, fracture toughness, and thermal conductivity. High hardness maintained at elevated temperatures (see figure 1) is key to thehigh-speed application of these tools and givesdramatic performance advantages over coated carbide tools. The combination of high hardness,good thermal conductivity, and high fracture toughness results in a very consistent, reliable toolthat excels in demanding cast iron applications.

In the 1980s and early 1990s, hot pressed siliconnitride ceramics were used in very few gray castiron machining applications. The introduction ofKennametal’s Kyon 3500 in 1993 changed that.Using breakthrough technology, KY3500 was produced using basic powder metallurgy methodsand eliminated the need for onerous hot pressing.Today, Kyon 3500 remains the industry standard asthe most dependable commercial ceramic grade on

Metallurgy and Machinability

Cast irons are iron-carbon-silicon alloys containinglarge amounts of carbon either as graphite or asiron carbide. They have higher carbon (>1.7%) and silicon (1.0-3.5%) contents than steel. Siliconpromotes dissociation of iron carbide to iron andgraphite. By increasing the silicon content in castiron, a greater proportion of graphite can beobtained at the expense of combined carbon.The microstructure and mechanical properties ofcast irons can be controlled not only by chemicalcomposition but also by cooling rate. Increasing thecooling rate will refine the graphite size as well asthe matrix structure and will increase strength andhardness. It also may increase the chilling tendency, which may increase the hardness butdecrease the strength.

Alloys within the broad group of cast irons includewhite iron, gray cast iron, mottled cast iron, malleable cast iron, and ductile cast iron. Each of these alloys may be modified by alloy additionsto obtain specific properties. Below are selectedASTM standards for different classes of cast irons.

Metallurgy Overview Machinability Overview

Machinability refers to the ease with which a workpiece can be machined and measured interms of tool life, metal removal rates, surface finish, ease of chip formation, or cutting forces.It is not an intrinsic property of a material, but is a result of complex interactions between themechanical properties of the workpiece, cuttingtools, lubricants used, and machining conditions.

Cast iron machinability varies greatly depending onthe type of iron and its microstructure. Ferritic castirons are easiest to machine, while white irons areextremely difficult to machine. Other grades of cast iron, such as malleable, ductile, compactedgraphite, and alloyed cast irons, are in between fer-ritic and white irons in ease of machinability.Additionally, hard spots in castings formed during rapid cooling and in presence of excessivelevels of carbide forming elements can seriouslydegrade machinability.

Alloy cast irons (ASTM A532, A518) can be classified as white cast irons, corrosion-resistantirons, and heat-resistant irons. Generally, they arebased on the iron (Fe) - carbon (C) - silicon (Si)system and contain one or more alloying elementsthat are added (>3%) to enhance one or more useful properties (corrosion resistance or strengthor oxidation resistance at elevated temperatures).Small amounts of ferrosilicon, cerium, or magnesium that are added to control the size,shape, and distribution of graphite particles arecalled inoculants, rather than alloying elements.Inoculation does not change the basic compositionor alter the properties of the constituents in themicrostructure. The alloyed irons for corrosionresistance are either 13-36% nickel (Ni) gray andductile irons (also called Ni-resist irons) or high silicon (~14.5% Si) gray irons. For elevated temperature service, nickel (Ni), silicon (Si), or aluminum (Al) alloyed gray and ductile irons are employed.

White cast irons, also known as abrasion-resistantcast irons, are an iron-carbon alloy in which the car-bon content exceeds 1.7%. White cast iron doesnot have any graphite in the microstructure.Instead, the carbon is present either as iron-carbide or complex iron-chromium carbides (Figure 1), which are responsible for high hardnessand resistance to abrasive wear. White iron showsa white, crystalline fracture surface because fracture occurs along the carbide plates. White ironcan be produced either throughout the section oronly on the surface by casting the molten metalagainst graphite or metal chill. In the latter case, it is referred to as chilled iron.

Corrosion-resistant cast irons obtain their resistance to chemical wear primarily from theirhigh alloy content of silicon, chromium, or nickel.Depending on which of the three alloys dominatesthe compositions, the corrosion-resistant materialcan be ferritic, pearlitic, martensitic, or austenitic.

Machinability – Alloy Cast Irons

White irons and corrosion-resistant high-silicon(14.5%Si) gray irons are the most difficult cast ironsto machine. Alloyed white irons such as nickel-hard(Ni-hard) alloys and high-silicon irons (ASTM A518)are generally ground to size or turned with a polycrystalline cubic boron nitride (PCBN) toolmaterial such as Kennametal grades KB9640,KD120, or KB5625

Gray cast irons (ASTM A48, A126, A159, ASMEAS278 and SAE J431) are named such becausetheir fracture has a gray appearance and consistsof graphite flakes embedded in a matrix of ferrite orpearlite, or a mixture of the two depending on thecomposition and cooling rate (Figures 2a-2d).Ferrite is a soft, low-carbon alpha iron phase withlow tensile strength but high ductility. Pearlite con-sists of lamellar plates of soft ferrite and hardcementite. Gray irons contain 2.5 to 4% carbon (C),1-3% silicon (Si), and manganese (Mn) (~0.1% Mnin ferritic gray irons and as high as 1.2% Mn inpearlitic gray irons). Sulfur (S) and phosphorus (P)may be present as residual impurities. Manganeseis deliberately added to neutralize the sulfur. Theresulting manganese sulfide is uniformly distributedin the matrix of gray iron as inclusions.

ASTM specification A48 classifies gray cast irons in terms of tensile strength (class 20 with 20 ksi

minimum tensile strength to class 60 with 60 ksiminimum tensile strength). The fluidity of liquid grayiron and its expansion during solidification due tothe formation of graphite are responsible for the economic production of shrinkage-free, intricate castings such as engine blocks. Most grayiron components are used in the as-cast condition.However, for specific casting requirements, theycan be heat treated (annealed, stress relieved, or normalized). Other heat treatments include hard-ening and tempering, austempering, martempering, and flame or induction hardening.

Figure 2c: Coarse pearlite ingray cast iron

Figure 2d: Pearlitic gray cast iron

Machinability – Gray Cast Irons

Most gray cast irons are easier to machine thanother cast irons of similar hardness and virtually all steels. This is because the graphite flakes in themicrostructure act as chip breakers and serve as a lubricant for the cutting tool. Machining difficultiescan still occur in gray iron if chills are present in corners and thin sections or when sand isembedded in the casting surface. The material also shows a tendency to break out during exitfrom the cut. Although the graphite in cast ironimparts its free-machining characteristics, thematrix surrounding the graphite determines toollife. In fully annealed state, cast irons have a ferritic matrix and exhibit the best machinability.(While not as soft as ferrite in steel, the ferritic castiron shows better machinability than ferritic steeldue to the slight hardening effect of the dissolvedsilicon and the chip breaking and lubricating effectof the graphite.) As the ferrite content decreases

and pearlite increases, tool life decreases rapidly.Both iron and alloy carbides, when present aslarge particles, are detrimental to tool life. Ironswith higher phosphorous contents (~0.4%) form a hard constituent called steadite, which has adetrimental effect on tool life.

Gray cast irons are productively turned and milledwith multi-layered alumina and TiCN coatedinserts. The substrate tool material can be eithercarbide or silicon nitride-based ceramic. Cermetgrades such as KT315 are ideal for light depth-of-cut applications. A pure silicon nitride grade suchas KY3500 often yields the highest productivity on general turning and milling applications at highspeeds. Drilling applications are highly dependenton the drill geometry as well as drill grade.Kennametal solid carbide drills in the TF (tripleflute) and SE (sculptured edge) geometries inTiALN-coated grades KC7210 and KC7215 are the most desirable. For indexable insert drillingapplications, TiALN-coated KC7725 and aluminacoated KC7935 grades are the first choice for high-speed, high productivity applications.

Ductile (nodular) irons (ASTM A395, A476,A439, A536 and SAE J434), previously known as nodular iron or spheroidal-graphite cast iron,contain nodules of graphite embedded in a matrixof ferrite or pearlite or both (Figures 3a-3c). Thegraphite separates as nodules from molten ironduring solidification because of additives cerium(Ce) and magnesium (Mg) introduced in the molten

iron before casting. The nodules act as crackarresters and impart ductility to the material. Bycontrast, neither white iron nor gray iron shows asignificant amount of ductility. Ductile iron is ofhigher purity (low phosphorus [P] and sulfur [S])and is stronger than gray iron.

With a high percentage of graphite nodules present in the microstructure, the matrix determines the mechanical properties of ductileiron. Table B compares the composition of ductileiron with that of gray iron and malleable iron.

The ASTM classifies different grades of ductileirons in terms of tensile strength in ksi, yieldstrength in ksi, and elongation in percent. Forexample, ASTM A536 specifies five standard ductile iron grades: 60-40-18 / 65-45-12 (ferriticductile iron), 80-55-06 (ferritic-pearlitic ductile iron),100-70-03 (pearlitic ductile iron), and 120-90-02(quenched and tempered martensitic ductile iron).

Ferritic ductile iron — the ferrite matrix providesgood ductility and impact resistance and tensilestrength equivalent to low-carbon steel. Ferriticductile iron can be produced “as-cast” or may begiven an annealing treatment to obtain maximumductility and low-temperature toughness.

Ferritic-pearlitic ductile irons — usually produced in the “as cast” condition and featureboth ferrite and pearlite in the microstructure.Properties are intermediate between ferritic and pearlitic ductile irons.

Pearlitic ductile irons - the pearlitic matrix provides high strength, good wear resistance, and moderate ductility and impact resistance.

While the aforementioned three types of ductile ironare most common and used in as-cast condition, ductile irons also can be alloyed and/or heat-treated to provide additional grades as follows:

Martensitic ductile irons are produced using sufficient alloy additions to prevent pearlite formation, and a quench-and-temper heat treatmentto produce a tempered martensitic matrix. Thesematerials have a high strength and wear resistancebut lower levels of ductility and toughness. Bainiticductile irons are produced through alloying and/orby heat treatment to provide a hard, wear-resistantmaterial. Austenitic ductile irons are producedthrough alloying additions to provide good corrosionand oxidation resistance, magnetic properties, and strength and dimensional stability at high temperatures.

Machinability - Ductile Irons

The spherical graphite in ductile iron acts similar tothe flake graphite in gray iron in chip breaking andlubrication in machining. Machinability increaseswith silicon content up to 3%, but decreases significantly at higher silicon levels. As in the caseof gray cast iron, machinability decreases withincreasing pearlite content in the microstructure.Finer pearlite structures also decrease machinabili-ty. Still, pearlitic ductile irons are considered to havethe best combination of machinability and wearresistance. Cast irons with tempered martensiticstructure have a better machinability than pearlitewith similar hardness. Other microstructures suchas acicular bainite and acicular ferrite formed during heat treatment of ductile irons have machinability similar to martensite tempered to the same hardness. The higher tensile strength ofductile irons compared to gray cast iron requiresbetter rigidity within the machining system. Tool per-formance life may be slightly lower if run at gray cast iron surface speeds.

Ductile cast irons can be productively turned andmilled with multi-layered alumina and TiCN or PVDTiALN-coated inserts but at slightly slower speedsthan gray cast irons.

Malleable cast irons (ASTM A602 and A47)consist of uniformly dispersed and irregularly

shaped graphite nodules (often called “tempergraphite” because it is formed by the dissolution of cementite in the solid state) embedded in a matrix of ferrite, pearlite (Figure 4), or temperedmartensite. Malleable iron is cast as white iron and then heat-treated to impart ductility to an otherwise brittle material. Malleable iron possessesconsiderable ductility and toughness due to thenodular graphite and a lower carbon metallicmatrix. It has good fatigue strength and dampingcapacity, good corrosion resistance, good magneticpermeability, and low magnetic retention for magnetic clutches and brakes. Malleable iron, likemedium-carbon steel, can be heat treated to obtaindifferent matrix microstructures (ferrite, pearlite,tempered pearlite, bainite, tempered martensite, ora combination of these) and mechanical properties.

Malleable and gray irons differ in two respects: theiron carbide is partially or completely dissociated in malleable cast iron; the dissociation occurs onlywhen the alloy is solid. However, the dissociation ingray cast iron occurs during the early stages ofsolidification; hence the difference in the characterof graphite in each material.

Figure 4: Coarse pearlite in annealed malleable iron

Machinability – Malleable Cast Irons

The machinability of malleable iron is considered tobe better than that of free-cutting steel. Use low-strength ductile iron machining recommendations.

Austempered ductile irons (ADI) (ASTM A897-90)are used as cast, but some castings are heat treated to achieve desired properties. Austemperedductile irons are produced from conventional ductile iron through a special two-stage heat

Photomicrographs courtesy of Buehler Ltd., Lake Bluff, Illinois, USA, www.buehler.com

treatment. The microstructure consists of spheroidal graphite in a matrix of acicular ferriteand stabilized austenite (called ausferrite) (Figure5). The fine-grained acicular ferrite provides anexceptional combination of high tensile strength withgood ductility and toughness. ADI can be given arange of properties through control of austemperingconditions. Compared to conventional grades ofductile iron, ADI offers twice the tensile strength fora given level of elongation.

Figure 5: Austempered ductile iron

Machinability – Austempered Ductile Irons

The machinability of the softer grades of austempered ductile iron (ADI) is equal or superiorto that of steels with equivalent strength. ADI can bemachined complete in the soft, as-cast state beforeheat treatment. This enables faster machine feedsand speeds and significantly increases tool life.

As the hardness of ADI increases, tool life decreases substantially. For this reason, only the 125/80/10 and 150/100/7 grades of ADI are machined after austempering. Processingsequence for parts processed to the higher strength:

• cast the component

• subcritically anneal to a fully ferritic matrix

• machine

• austemper

• finish machine (if required)

• finish operations (rolling, grinding, peening, if required)

Follow high-strength ductile iron recommendationsduring machining.

Compacted graphite iron (CGI) (ASTM A842)has a microstructure in which the graphite is interconnected like the flake graphite in gray castiron, but the graphite in CGI is coarser and morerounded (Figure 6). In other words, the structure ofCGI is between that of gray and ductile iron. Thegraphite morphology allows better use of thematrix, yielding higher strength and ductility thangray irons. The interconnected graphite in CGI provides better thermal conductivity and dampingcapacity than the spheroidal graphite in ductileiron. Although the CGI is less section-sensitivethan gray iron, high cooling rates are avoidedbecause of the high propensity of the CGI for chilling and high nodule count in thin sections.

Figure 6: Compacted graphite

Machinability – Compacted Graphite Iron

The graphite morphology in compacted graphiteiron enables chipbreaking but is strong enough toprevent powdery chip formations. This combinationis ideal for good machinability. As a result, themachinability of compacted graphite iron liesbetween that of gray iron and ductile iron for agiven matrix structure. Use low-strength ductile ironmachining recommendations.

Machinability Data – Cast Iron

Gray Cast Iron

The ideal turning insert geometry for machininggray cast iron should have the following characteristics:

• square or diamond shaped for maximum strength

• negative insert geometry for maximum strength and number of cutting edges

• minimum or no positive-rake chip-forming insert geometry for maximum edge strength

• medium edge hone on carbide inserts and a T-land edge prep on ceramic/sialon-gradeinserts

Pre-chamfer workpiece whenever possible to avoidworkpiece material breakout and interrupted cutshock damage to insert edge.

Ductile Cast Iron

The ideal turning insert geometry for machiningductile cast iron should have the following characteristics:

• square or diamond shaped for maximum strength

• negative insert geometry for maximum strengthand number of cutting edges

• positive-rake chip-forming insert geometry forfreer cutting action and chip control

• light edge hone on carbide inserts and a T-landedge prep on ceramic/sialon-grade inserts

Insert Edge Preparation

3. T-land plus hone

In aggressive applications, such as interrupted turning, chipping can occur at the intersection ofthe T-land and flank surface of the ceramic insert.This condition may be eliminated by applying asmall hone to the intersection while leaving theother attributes of the T-land unchanged.

Edge Preparation for Kennametal’s Advanced Cutting Tool Materials

Edge preparation is the term for the intentionalmodification of the cutting edge of an indexableinsert to enhance its performance in a metalcutting operation.

Ceramic cutting tool materials have a much higher hardness, but lower toughness, compared to conventional carbide materials. Because of this,ceramic materials have good bulk strength butlower edge strength versus carbide.

To optimize performance of ceramic cutting tools, it is critical that tool material, workpiece material,and machining conditions be considered relative toedge preparation. To achieve optimum edge preparation, make the minimum amount of modification necessary to distribute forces sufficiently enough to prevent chipping and catastrophic insert failure. Edge preparations forstandard inserts made with specific ceramic gradesare determined by target applications and listed inthe KENNA PERFECT insert selection system.

There are three choices of edge preparation forceramic materials:

1. T-land

2. hone

3. T-land plus hone

1. T-land

T lands protect the insert cutting edge by directingforces into the greater part of the insert, ratherthan to the smaller cross section of the sharpedge, during the metalcutting process. This helpsprevent chipping and catastrophic failure.

There is a tradeoff to the benefits of this edge preparation. Increasing the width “T” of the T-land orthe angle “A” increases the overall cutting forcesacting on the insert. This can negatively affect the wear rate of the insert and/or deformation of a thin-walled workpiece.

For most cast iron turning applications, use a T-landwidth smaller than the feed rate. For heavily interrupted turning, hard turning (workpiece >50HRC), and milling applications, use a T-land widthlarger than the feed rate.

2. Hone

Hones protect the insert cutting edge by eliminating the sharp edge and distributing the cutting forces over a larger area. Hones generallyare recommended for continuous or finishing operations; however, depending on the workpiecematerial, they can be used for interrupted or heavy cutting.

Three Ways To Improve Your Turning Operations!

Conventional Turning Insertdoc ............0.050feed ..........0.012 iprspeed ........1,100 sfmfinish ........160 Ra (µin.)

Kennametal Wiper Technology –MWdoc ................0.050feed ................0.020 iprspeed..............1,100 sfmfinish ..............60 Ra (µin.)

Kennametal introduces three new geometries that are the latest in state-of-the-art turning technology. Our new -RW (Roughing Wiper), -MW (Medium Wiper) and -FW (Finishing Wiper) inserts employ a modified corner radius design that delivers a superior surface finish compared to conventional inserts. This technology allows you to choose the metalcutting benefit that’s most important to your application.

Double ProductivityKennametal’s new wiper geometries allow you to double your current feed rate and still achieve surface finishes comparableto conventional inserts. You’ll also see equivalent or better tool life using the appropriate KENNA PERFECT grade specificallydesigned for your workpiece material.

Better Workpiece FinishThese new wiper geometries also will give you a markedly improved surface finish at your current machining conditions. Under typical conditions, you’ll see as much as a 250% improvement in the workpiece surface finish, all with inserts that meet your corner radius specifications.

You choose! Either way, we’re sure you’ll agree that the new wiper geometries from Kennametal provide an outstanding way to optimize your turning operations. Please see the accompanying information for proper application guidelines.

Application Guidelines – Cast Iron

Nose Radius Selection and Surface Finish for Conventional Inserts*

Nose radius and feed rate have the greatest impacton surface finish. To determine the nose radiusrequired for a theoretical surface finish, use the following procedure and the chart above.

Locate the required surface finish (rms or AA)on the vertical axis.

Follow the horizontal line corresponding to thedesired theoretical finish to where it intersects the diagonal line corresponding to the intended feed rate.

Project a line downward to the nose radiusscale and read the required nose radius.

If this line falls between two values, choose the larger value.

• If no available nose radius will produce therequired finish, feed rate must be reduced.

• Reverse the procedure to obtain surface finish from a given nose radius.

*NOTE: See pages 57-59 for radius and surface finish specifications using wiper-style inserts.

NOTE: Peaks produced with a small radii insert (top) comparedto those produced with a large radius insert (bottom).
