Setting up the workpiece

6-15
The surface of the table could be scratched when sliding the work-
piece, thus affecting measuring accuracy.
Damage caused by hard particles.
Any hard particles lying underneath the workpiece may lead to inaccu-
rate measurements. Furthermore, the surface of the measuring plate
and workpiece may become damaged.
ü
The workpieces must have full contact with the measuring plate.
—
Clean the measuring plate before placing a workpiece or a clamping
device on it.
—
Always clamp the workpiece in such a way that it lies on the defined
points of support (three-point support). This can be achieved, for ex-
ample, by means of a clamping device.
Lowering the workpiece onto the measuring
plate
Workpieces can be set down on the measuring plate either manually or
by means of a lifting device.
SIPOS Activate SIPOS when using a lifting device to set down workpieces on
the measuring plate. SIPOS is an optional device which controls the
travel movements of the CMM and the loading device.
Heavy workpieces Heavy workpieces have a hard impact if they are lowered onto the mea-
suring plate too quickly.
1 Lower heavy workpieces at a maximum speed of 2 mm/s.
2 First place the workpiece on elastic supports.
3 Then replace the elastic elements with rigid supports.
Metal blocks clamped by clamping devices can be used as rigid sup-
ports. Screw elements can be used alternatively. The screw fasteners
must be screwed into the threaded holes in the measuring plate.
Positioning the workpiece
Position the workpiece so that all required measurements can be carried
out without changing the workpiece position.
Measuring operation
without collision
When using a changer rack, position the workpiece so that the measure-
ment and the stylus system change can be carried out without collision.
