9 Digitizing 3D Surfaces
Executing a part program from digitized data
Before the digitized data program can be transferred blockwise
(see page 3-6) and executed, the TNC must receive the following informa-
tion from another program:
• Tool radius and length
• Feed rate of tool
• Radius compensation
• Spindle axis and rpm
• Miscellaneous function for spindle
The program must contain the following five lines:
0 BEGIN PGM 444 MM ......................................... Any program number
1 TOOL DEF 1 L+30 R+4 ...................................... Tool
2 TOOL CALL 1 Z S1000 ....................................... Tool axis and spindle speed
3 L R0 F500 M3 ..................................................... No radius compensation
4 L R F M xy .......................................................... M xy: M function defined by the machine builder, through
which the tool, feed rate and direction of spindle
rotation remain effective even when a new program
(the digitized data program) is selected.
5 END PGM 444 MM
At the end of the digitized data program generated by the CONTOUR LINES cycle, the tool is returned to the pro-
grammed starting point.
