Simple and easy, but limited
Put QM-Measure on your shop-floor . . .
Hand tools are certainly a common part of product inspections. They have certain benefits, of course, including simple operation. Each of these tools, however, can only measure a single axis within a single dimension: outside/inside diameter, height, depth, etc. This means a variety of different tools is required for complete measurement. Overall, it’s a costly and time-consuming way of doing things.

Ordinarily, a solid backgrounding in geometry is required for 3-D measurement using a coordinate measuring machine. But Mitutoyo offers an easy, automated solution. With QM-Measure you can complete the 3-D measurement process simply by following the messages displayed onscreen. A special Gage-like measurement menu makes it fast and accurate . . . and you won’t need a math degree to it.QM-Measure adapts to varying temperature conditions, too, with an optional Temperature Compensation System that lets you evaluate workpiece dimensions at 20°C (68°F) in an ambient shop-floor temperature ranging from 15°C (59°F) to 30°C (86°F).
say goodbye to hand tools!

QM-MeasureFlexible yet precise
Open-space designThe QM-Measure’s unique “open-space” structure makes it easy to load and unloaded your workpieces. Moreover, it lets the shop operator to approach the workpiece free of obstruction by the machine column.
Accuracy in measurementThe QM-Measure system delivers accuracy of E=(3.0+4L/1000)µm. This means you can measure 300mm volumetric length with an indication error of less than 4.2µm.
With Linear ScaleA glass linear encoder is employed as a length standard of all axes. Featuring high resistance to rust and corrosion, it offers a long service life and remarkable reliability.
Rigid air bearingsOptimized machine balance and air bearings on all guideways ensure smooth, worry-free probing for 3-D measurement. Operating fatigue is minimized, too!
Air regulatorThe QM-measure is supplied with a standard air regulator, which monitors the condition of the air supply* and removes any remaining mist or oil.* An additional air dryer and mist separator
may be required, as per conditions of use.

Convenient key operationThe QM-Data 300 (data processing unit) can change the mounting position and angle in response to measurement conditions. Key operation makes it easy!
Temperature compensationThe useful Temperature Compensation function lets you evaluate workpiece dimension at as little as 20°C (68°F), even when shop or workpiece temperatures are not at 20°C (68°F). In fact, QM-Measure works within a temperature range of 15°C to 30°C (59°F to 86°F) with no effect on accuracy.
This chart presents simulated stress distribution when the X-axis slider is moved to the stroke end and 20kg load is applied to it. Even then, stress does not produce an accuracy deterioration over prolonged use.
An optional-temperature compensation system---featuring two temperature sensor units---is available for automatic detection of temperature.
Enhanced volumetric accuracyDeformation of the X-axis guide due to movement of the X-axis slider is compensated as follows:
This chart indicates volumetric measuring accuracy under various environmental temperatures (20°C - 15°C - 20°C - 30°C - 20°C), each with guaranteed measurement result.

QM-Data 300Simple, intuitive operation
A gage-like measurement menuThe coordinate system setup is indispensable when a conventional CMM is used. However, this can be lead to the impression that “CMM operation is difficult”. But QM-Data 300 provides a gage-like measurement menu that frees you from such concerns. Simply touch the features of the workpiece with a touch trigger probe, following the interactive graphic display. The measured geometry is immediately calculated and displayed. It’s so easy, even a beginner can perform volumetric measurement.

Mitutoyo’s “AI” FunctionMitutoyo’s exclusive “AI” function even frees you from the need to select geometric features (step 1 right). Based on input data, the QM-Data 300 identifies which geometric features is measured, then shows the appropriate graphic display and calculates the dimensions automatically. This lets the operator continue the process without interruption using simple keystrokes.The following geometric features are supported;• Point • Line • Plane • Circle• Cylinder • Cone • Sphere
How does the AI function simplify key operation?Example: Parallelism between two cylinders
The QM-Data 300 automatically identifies “Cylinder” from the input data.

Multiple language supportSeveral operating languages are available: English, Japanese, German, French, Italian, Spanish and Portuguese
Rapid access with the 1-Key function The QM-Data 300’s unique 1-Key function lets you call a desired menu display* with a single press of an alphabetic key, as shown in the example below. If you have a frequently-used menu display, simply assign it to one of the alphabetic keys (A to Z). The registered menu display is called up instantly by jumping through the hierarchical menu structure.*All the menu displays in the main menu category, user menu displays (page 1 to 4) and 1-Key list display are available for assignment except for the gage-like measurement menu displays.
Using 1-Key function
Selectable display mode An Enlarged display mode and Probe Position display mode are selectable in addition to the standard display mode.
“Learn and Repeat” functionThis function is particularly convenient for the repeated measurement of identical workpiece dimensions, such as when sampling for quality control. Using the Learn mode, a sequence of key operations is stored in the internal memory or on floppy disk* as a part program. It can be executed in the Repeat mode to reproduce the measurement routines without your having to handle key operations at each step of measurement. The Edit function is available for deleting/inserting/modifying a command in the registered part program. For faster access and execution, the name of the part program can be assigned to an icon in the user menu.*When using an optional floppy drive.
Sample of User Menu
Standard key operation
Allocation-free user menu displaysThe QM-Data 300 lets you design an original menu display (user menu). Simply choose a desired icon from the main menu category* and copy it to a blank icon (F1 to F12) in the User Menu display. The registered macro and part program will then be assigned to the blank icon. *Exclude gage-like measurement menu displays. 4 pages with 48 blank icons
Enlarged display modeSimple indication of XYZ probe position
Probe Position display modeGraphically indicating the current probe position
Macro functionThis function lets you create and register macros comprising sequential multiple commands converted from a part program. Moreover, your macros can be assigned to icons in the user menu, thereby automating your combined calculations and otherwise complicated measurements. Mitutoyo preregisters the nine most useful macros* as standard features.* Intersection/angle, Circle/line intersection, two-circle intersection, three-plane intersection,
two-plane angle, Plane/cylinder angle, Projected distance, Spatial distance and Square hole measurements
• Macro icons • Icon for part program execution
• Icons copied from other menu display
Original iconsA BMP data (16-color. 64x64dot) can be registered as an icon for the user menu.

• QMStat –evaluating SPC parameters– The QMStat features a
comprehensive selection of SPC parameters:• Average, Max., Min.,
Sigma,Cp/Cpk • Histogram • X-Rs control chart • Run chart
For Advanced MeasurementIn addition to gage-like measurement menus, the QM-Data 300 provides the experienced operator with a host of advanced functions equal to those of standard CMM software.
Coordinate System Setup
Measurement menu
Parameter-parameter calculation menu
Optional programs• QMFit –creating the best fit coordinate system–
The QMFit can translate and rotate the part coordinate system so that the measurement results of workpiece features most closely match their nominal values using the “least square” method algorithm. This is very suitable for measuring parts having low dimensional accuracy, such as press and injection-molding components.
• QMGraph –visualizing measurement results–The QMGraph shows the calculation results of geometrical deviations and tolerance assessments with easy-to-understand drawings.• Geometrical deviation: Straightness, flatness, circularity• Tolerance assessment: Positional deviation, XYZ coordinate value
• QMScan –digitizing 3-D contour–The QMScan uses a hard probe to scan and digitize workpiece contours. The contour-point clouds thus obtained can then be transferred to an external contour modeling system via floppy disk or the RS-232C interface.
