5.4 Using Digitized Data in a Part
Program
Resulting NC blocks of a file containing data that
were digitized with the CONTOUR LINES cycle.
A surface-data file can have up to 1500 MB. This is the available
memory capacity of the TNC’s hard disk if no other programs are
stored.
0 BEGIN PGM DATA MM Program name DATA is entered in the RANGE cycle
1 BLK FORM 0.1 Z X-40 Y-20 Z+0 Define workpiece blank: The size is determined by the
TNC
2 BLK FORM 0.2 X+40 Y+40 Z+25
3 L Z+250 FMAX Clearance height in Z is entered in the RANGE cycle
4 L X+0 Y-25 FMAX Starting point in X/Y is entered in the CONTOUR
LINES cycle
5 L Z+25 Starting height in Z is entered in the CONTOUR
LINES cycle and depends on the algebraic sign of the
line spacing
