A workpiece contour is usually composed of several contour
elements such as straight lines and circular arcs. With the path
functions, you can program the tool movements for straight lines
and circular arcs.
FK free contour programming
If a production drawing is not dimensioned for NC and the
dimensions given are not sufficient for creating a part program,
you can program the workpiece contour with the FK free contour
programming. The control calculates the missing data.
With FK programming, you also program tool movements for
straight lines and circular arcs.
Miscellaneous functions M
With the control's miscellaneous functions you can affect
the program run, e.g., a program interruption
the machine functions, such as switching spindle rotation and
coolant supply on and off
the path behavior of the tool
