How many kinds of gages are necessary for accurate
inspection?
Put QM-Measure on your shop-ﬂoor . . .
Simple and easy, but limited
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.

say goodbye to hand tools!
“Gage-like” operation and Flexibility
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).

with optional accessories
Accuracy in measurement
The 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.
Open-space design
The 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.
With Linear Scale
A 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 bearings
Optimized machine balance and
air bearings on all guideways
ensure smooth, worry-free probing
for 3-D measurement. Operating
fatigue is minimized, too!
Air regulator
The 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.

Optimized machine rigidity
Temperature compensation
In choosing an open-space structure for the QM-Measure system,
Mitutoyo optimized the body design through FEM (ﬁnite-element
method) analysis, thus minimizing machine deformation and related
concerns during the probing.
The 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.
An optional-temperature
compensation system--featuring two temperature
sensor units---is available
for automatic detection of
temperature.
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.

The 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” Function
Mitutoyo’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
• Cylinder • Cone
• Plane
• Sphere
Step 2
Probe the workpiece to measure the
second cylinder, then press the
key to complete the measurement*.
• Circle
The QM-Data 300 automatically
identiﬁes “Cylinder” from the input
data.
How does the AI function simplify key operation?
Example: Parallelism between two cylinders
Step 1
Probe the workpiece to measure the
ﬁrst cylinder, then press
key to
complete the measurement*.
Step 3
Press the
key three times to
begin the parallelism calculation.

Rapid access with the 1-Key function
“Learn and Repeat” 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.
This 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.
*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.

Macro function
This 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
Allocation-free user menu displays
The 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.

For Advanced Measurement
Optional programs
In 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.
• 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.
Coordinate System Setup
• QMGraph –visualizing measurement results–
The QMGraph shows the calculation results of geometrical
deviations and tolerance assessments with easy-to-understand
drawings.
Measurement menu
• Geometrical deviation: Straightness, ﬂatness, circularity
• Tolerance assessment: Positional deviation, XYZ coordinate value
Twelve handy macro icons preregistered
Parameter-parameter calculation menu
• 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.
• QMStat
–evaluating SPC parameters–
The QMStat features a
comprehensive selection of
SPC parameters:
