8.6.6 Extending of the program for the lowering of the tool
The prepared program test.din follows a circular contour.
The real objective of a CNC program is the starting of a tool
during the following of a con-
tour. The existing program Quad1.din is, therefore, extend
ed by the respective M-functions
M14 and M15 that lift and lower the tool only in case of a following of the contour. The M-
functions are programmed in a separate PLC program.
