HOLOS closes the process chain.

Utmost precision with minimum

data quantities

HOLOS can read data from all typical CAD surface

descriptions (Bezier surfaces, B-splines, NURBS).

NURBS is particularly suited for using workpiece data

from the design department for quality control pur-

poses without any loss in quality. The reduced data

quantity guarantees high processing speed.

HOLOS enables Reverse-Engineering.

The wide basis of information

technology is clearly dominated

by Windows NT and UNIX.

Following this trend, HOLOS is

not platform-dependent and can

be used with Windows NT and

UNIX and therefore in any exist-

ing system environment.

Reliable and fast

data exchange

HOLOS operates with standard interface formats

such as VDAFS and IGES, for example. You can transmit

workpiece data directly from your production or design

department and use it to generate measuring

programs.

Reverse Engineering.

Because your customers

need data.

For the process chain to be completely closed, it is

not enough to be able to read and understand data

formats. Re-engineering work or copy milling in

the design area (using a Zeiss horizontal-arm CMM

equipped with an articulating milling head) can only

be performed if surface descriptions are generated

from point data and converted into a format which

can be read by the CAD or CNC system.

HOLOS is the ideal tool for turning your CMM into

a digitizing unit. HOLOS supplies surface descriptions

in the form of Bezier surfaces or NURBS in the data

exchange format requested by your customer or used

in your existing process chain.

HOLOS saves time and is not

subject to system limitations.

From the design department via model and mold

making to the actual production floor, the same data

record is used for all steps involved in the process

chain. HOLOS provides clear-cut data exchange and

correct transfer of surface descriptions. This saves time

and eliminates errors.

HOLOS works under

Windows NT and UNIX.

HOLOS. Measuringcan be so simple.

Work with HOLOS offers you

all the benefits of menu driven

operation. HOLOS automates

even complex measuring opera-

tions. This saves measuring

and programming times and mini-

mizes error sources.

See what you measure.

With the appropriate CAD data available, you can

see any section of a workpiece in any perspective true

to scale on your monitor. A simple mouseclick is needed

to rotate the displayed component through any axis,

in any direction and to zoom any detail.

With HOLOS, a

measuring program is

generated directly by

simply clicking on

measuring or reference

points. The measuring

run is stored and

simulated on screen.

Measuring program per

mouseclick

HOLOS permits measuring programs to be gene-

rated with unprecedenteded speed. Create them by

simply clicking on measuring or reference points on the

illustrated component, depending on the measuring

method selected. And HOLOS executes at the same

time the measuring order activated last.

The advantages of HOLOS can also be used for

off-line programming so that your valuable coordinate

measuring machine can be used to capacity for

measuring only.

Correcting CAD data without

involving your design department.

HOLOS utilizes CAD data with its complete layer

structure. Existing surface elements can be deleted,

masked, rotated, reversed and displaced on all layers

provided by the CAD system. This means that you your-

self can edit the CAD models to meet the respective

metrological requirements. You make matters easy for

your design department and are metrologically inde-

pendent.

And should you find during the production run that

additional measurement will be required, HOLOS

allows you to add standard geometric elements, e.g.

a borehole, to the existing CAD component description.

HOLOS permits the

generation of complete

workpieces from

standard geometric

elements.

It is even possible with HOLOS to generate com-

plete workpieces consisting of standard geometric

elements (circle, plane, sphere, cylinder, cone, oblong

and rectanguar bore). When digitizing workpieces, this

function can prove to be extremely useful and time-

saving if you know the form and position of their stan-

dard geometric elements.

Time-saving correction and

reliable data input

Powerful CAD functions normally eliminate the

need to involve your design department, save time and

allow you to use your CMM without interruptions.

With HOLOS, existing CAD component

descriptions can be supplemented by standard

geometric elements.

HOLOS. Measuring without in-depth knowledge.

In the past, you had to switch

between different program modules

for different measuring tasks.

Not so with HOLOS. This program

package takes care of all other

tasks for you – you simply measure

and leave the rest to HOLOS.

Reliable measuring program

generation

HOLOS takes all information required for measure-

ment from CAD data records. No tedious manual entering

of nominal data, which means that an error source has

been eliminated. Whether you measure free-form surfaces

or standard geometric elements, HOLOS always provides

results of high information content.

No need for manual identification

of stardard geometric elements

HOLOS identifies CAD data which is stored as

stardard geometries. The characteristics (length, width,

diameter, etc.) of a geometric element are output auto-

matically in the result, permitting direct interpretation

of the measured data.

It is of course also possible to identify free-form

surfaces in the CAD data records which describe stan-

dard geometric elements.

This is how HOLOS

digitizes free-form

surfaces: curves and

surfaces are generated

from the captured

points.

Easy-to-operate menus

Clearly laid out pull-down menus help you to

compile and operate the measuring and digitization

programs. Menu items are easily located. You then

branch into the desired function and activate the item

by clicking on it with the mouse. Automatically preset

defaults are your guarantee of a logical measuring

or digitizing program.

Dialog for enhanced reliability

With conventional measuring equipment, you may

have to spend a long time troubleshooting if a (meas-

uring) error has caused a failure. HOLOS, however,

accompanies you through the entire run. The program

monitors whether all operational sequences are

complete and correct. During the actual measuring or

alignment procedure, HOLOS gives warning if any steps

have not been executed correctly. If an operation is

incomplete, HOLOS stops the measuring run. The need

for time-consuming troubleshooting following program

interruption is eliminated.

Intuitive operation in any

environment

Benefit from the easy and intuitive operation of the

user interface also in mixed system environments.

If you change from UNIX to Windows NT, or want to run

additional measuring machines under NT, you will not

require any expensive retraining.

Menu driven operation offers high reliability and

saves measuring and programming times.

HOLOS. The direct way to anerror-free measuring program.

HOLOS supports you when you

measure free-form surfaces and

standard geometries either on

manual or CNC coordinate

measuring machines. The complex

operational sequences provided

by conventional systems are

available in HOLOS as automatic,

easy-to-operate modules.

Complex alignment in a matter

of minutes

With conventional systems, one of the most time-

consuming jobs is the mathematical alignment of the

workpiece. HOLOS provides image and program

support for aligning the measurement object.

The workpiece to be measured with its CAD data is

graphically illustrated, arbitrary points are probed and

assigned in interactive graphic operation to the work-

piece.

Manual measurement

HOLOS also offers the possibility of performing

discrete-point measurements on your manual or

CNC CMM. Following probing, the results are displayed

immediately on the monitor in the appropriate position

of the workpiece illustration.

CNC measurement

Storing and recalling CNC measuring programs is

easy with HOLOS. The recalling of a measuring program

once stored is a rather lengthy procedure with con-

ventional systems. With HOLOS, you can start previously

stored measuring programs without any special skills.

This makes HOLOS ideal for in-process screening of

high-volume production with a flexible workpiece

spectrum.

Measuring programs created

in the learn mode

HOLOS automatically stores the discrete points

measured manually as a measuring program. This

eliminates the time-consuming, frequently error-prone

generation of a probe route required in conventional

learn programming.

Graphic, interactive programming

Clicking on a measuring point in question

is sufficient to define the point. No probe travel

is required. HOLOS then computes the travel paths be-

tween the selected measuring points. Since programm-

ing is performed without any CMM travel, it is possible

for HOLOS to compile a new program during the actual

measurement. This reduces machine idle times.

Intelligent software functions

reduce programming work

HOLOS offers a comprehensive range of tools

for the automatic generation of measuring runs. Points

on the edges of punched or deep-drawn pieces, for

example, or net profiles and net points can be measured

automatically.

Variable definition and evaluation

of tolerance fields

The evaluation of measured data is based on the

tolerances defined in HOLOS, with the possibility

of varying the distribution and evaluation of tolerance

fields on the surface elements.

HOLOS saves time and money

The automation of many measuring runs minimizes

the programming work and reduces machine idle times.

Simple interpretation

of results. Depending on

the task, a suitable

illustration is selected:

as freely positionable flags,

as chromatic coordinates,

as a vectorial or numeric

illustration, as coordinate

axes or with colored

markings.

Measurement results

along a surface

profile can be shown

as a vectorial view

on the workpiece

illustration along a

scanned line, or as a

two-dimensional

curve along the

nominal line.

HOLOS. Surface descriptionsare computed automatically.

The points captured when

digitizing do not have to be

edited by another system.

HOLOS automatically calculates

the surface description.

The steps required by conventional

systems, e.g. data conversion

and integration of other pro-

grams, are not required here.

From the scanned data,

HOLOS automatically

generates surface

descriptions in the

required CAD format.

Milling in the design area

When used with a horizontal-arm measuring

machine of the Design series and the articulating

milling head, HOLOS can be used for direct on-line copy

milling, with specific profile lines being scanned on one

half of the model and the milling work being performed

symmetrically on the other half. For the initial creation

of a design model, HOLOS can cut grid lines directly

into the prototype model on the basis of CAD data,

drastically reducing the time required to produce this

prototype model.

Not just point clouds,

but finished surfaces

There is no need to invest in additional systems for

solving complete reverse engineering tasks.

Profiling with HOLOS:

One half of the model is scanned and the other

is symmetrically milled with the articulating

milling head.

Instant provision of precise,

verified model information

From the surface data obtained during digitizing

with the CNC CMM, HOLOS directly computes the

relevant CAD information.

Such surface descriptions can be checked right

away, without an additional CAD system. You simply

use the newly generated surface description to perform

a verification measurement of the digitized surface.
