0 0 Forms without input fields for parameters:
_VMS: Measuring velocity
•
_NMSP: Number of measurements at the same location.
•
The following default values are entered in the NC code for the
parameters:
_VMS=0: corresponds to 150 mm/min or 5.9055 inch/min
•
_NMSP=1: number of measurements = 1
•
1 - Forms with input fields for parameters:
_VMS: Measuring velocity
•
_NMSP: Number of measurements at the same location
•
0 0 Screen forms for workpiece measurement with automatic tool
offset and tool measurement do not contain an input field for the
following parameters:
_EVNUM: Number of empirical value memory
•
The following default value is entered in the NC code:
_EVNUM=0: No empirical value memory is taken into
•
Settable zero offsets
Last channel-specific basic frame
Milling: Tool radius is corrected
Turning: Length offset in the measuring axis
Settable zero offsets
Last channel-specific basic frame
Offset in system frame
Offset in active frame
Offset in any basic frame (global or channel-specific)
Offset radius, length, or length selection (L1, L2, or L3)
Calculation of measurement results normal or inverted
