Digitizing
Digitizing 3D Surfaces
The machine and TNC must be prepared for digitizing by the
machine tool builder!
The TNC features the following cycles for digitizing with a measuring
touch probe:
• Fix the scanning range: TCH PROBE 5 RANGE
TCH PROBE 15 RANGE
• Digitize in reciprocating lines: TCH PROBE 16 MEANDER
• Digitize level by level: TCH PROBE 17 CONTOUR LINES
• Digitize in unidirectional lines: TCH PROBE 18 LINE
The digitizing cycles can be programmed only in plain language dialog.
They can be programmed for the main axes X, Y and Z as well as for
the rotary axes A, B and C.
• Digitizing is not possible while coordinate transformations
or a basic rotation is active!
• Digitizing cycles need not be called. They are effective
immediately upon definition!
