Loading and Fixing the Part
Section “Overall Dimensions and Mechanical Characteristics of the Measuring Machine” on page 39
indicates the maximum weight of a part that can be placed on the granite. Heavy parts should be positioned
towards the center of the granite to guarantee optimum stability of the machine.
The part and the fixtures may be fixed to the granite using the threaded inserts machined into the granite.
See the overall view drawings for the specific model in
section “Overall Dimensions and Mechanical
Characteristics of the Measuring Machine”.
Never apply a tightening torque of more than 20 Nm (180 in/lbs). Excessive
tightening of the bolts may cause the inserts to come unstuck or cracks to
appear in the granite work table.
Part weight compensation
The GLOBAL S measuring machine applies automatic corrections to the performed measurements to
compensate for geometric changes induced by the loads of parts onto the table.
To allow part weight compensation to work properly, the user is required to define some information relevant
to the specific measurement setup:
In the default case, assuming that the workpiece is placed centrally and symmetrically in the
measuring volume, only the weight of the workpiece is required.
In other cases, the layout of the support points of the workpiece on the granite table can be
specified in addition to the workpiece weight.
PC-DMIS and QUINDOS measuring programs are equipped with a specific interactive user interface to
enable/disable weight compensation and to enter the required data according to different options.
Description of the user interface options and relevant instructions for use are included in the online help of
both PC-DMIS and QUINDOS.
