MACHINE TOOLS /
ROTATION CHECKS
Measuring task:
A machine tool must be checked on possible geometrical
deviations. The check must show up eventual
rotations of the table during displacement.
The measurement of geometry should be made in a
quick, reliable and simple procedure ant thus
with a good cost benefit effect.

FLATNESS MEASUREMENT ON A CIRCULAR SUPPORT OF A
TURN TABLE
Measuring task:
The flatness of a circular support with 2.3m
diameter has to be measured.
|
|
 |
|
|
|
MACHINE TOOLS / SPINDLE
ALIGNMENT
Measuring task:
The deviation from the right angle between the
two working positions „horizontal“ and
„vertical“ must be determined.
This measurement is required
during the assembly,
 the
error correction by scraping when the unit is
mounted on a temporary frame with doubtful
stiffness as well as during the final inspection
of the ready mounted machine tool.
The measuring uncertainty
must not exceed two seconds of arc. Calculations
involved must be possible without the aid of a
computer.

MEASUREMENT OF THE ABSOLUTE POSITION
OF A GUIDE WAY
Measuring task:
For a guide way not only its straightness but
also its deviation from the horizontal plane
shall be measured. Furthermore it should be
determined where and how much should be
corrected to adjust the guide way horizontally.

Mechanical Engineering |
|
Measuring task:
With simple means the position of a cutting head
can easily be checked and adjusted if necessary.
Alternatively to the new adjustment of the tool
the table can be inclined and checked. |
|
Measuring task:
A huge bearing ring is being checked in the
frame of the
quality
assurance scheme on several points in respect of
the actual inclination. |
|
Measuring task:
Check of the adjustment angle of the tool on a
large rotating lathe.
|
|
|
|
|
Measuring and Calibration Laboratory
Measuring task:
On several measuring machines some pre-set
inclinations must periodically be checked and
re-adjusted if necessary.
Particularly on the
notched-bar impact testing machine
the set angle of the hammer is of direct
influence on the possibility to obtain a
reliable measuring result. This angle check can
easily be done with a CLINOTRONIC and is applied
by many calibration labs.
|
 |
|
|
|
Measuring task:
Each single colour unit provides horizontal
and/or vertical reference faces which must be
used during the manufacturing process in the
production plant as well as for the adjustment
of the printing line. The positions of the
reference faces must be adjusted in accordance
to each other, measured, and a record must be
printed. The positions of the printing cylinders
must be precisely aligned to each other
(horizontally).

POSITIONING OF A
HEAVY PART WITH AN OVERHEAD CRANE
Measuring task / Goal:
In order to achieve the required accuracy the
bending of the building respectively of the
overhead crane should be measured.
from these values the vertical correction of the
crane should be calculated.
|
|
|
|
|
MACHINE TOOLS / ANGULAR POSITIONING ERROR
OF A- AND C-AXES
Measuring task / Goal:
Measure deviation from anticipated angle on
different angular positions. As the centre of
the axis of rotation is often not accessible, an
additional challenge is added to the task. In
many cases the measured values are entered in
the CNC controller for corrective action. In
order to include errors due to mass of the
machine components the measurement should
therefore be collected near by the cutting
position. Uncertainty of measurement should not
be greater than 1 to max. 2 Arcsec.
