Specifying part fixturing (CNC option)
Default part fixturing is configured in the CNC General setup screen by OEMs and Distributors for CNC
systems. In most cases, part fixturing will remain unchanged. However, if fixturing requirements change,
the part fixture configuration can also be changed to insure that subsequent program runs will include the
correct measurement reference and datum.
Any of three fixturing modes can be selected in the Program Settings screen:
None
No part fixturing is used, a measurement reference and datum must be created by the user for each part
prior to measurements.
Temporary
Temporary part fixturing is used, a measurement reference and datum must be created for the first part by
the user, thereafter the system will perform measurement reference and datum measurements automati-
cally for each part.
Permanent
The part fixturing is permanently attached; this is a dedicated fixture. The system retains the measurement
reference and datum as part of the program, no user interaction is required to create a measurement refer-
ence or datum.
To specify the desired fixturing mode in a program:
1 Touch the Program tab to display programming tools.
2 Highlight the desired program and touch the Edit icon to display its program steps.
3 Touch the Fixturing Mode choice field repeatedly to cycle through the available fixturing modes.
