Useful configurations for the machine tool operator:
In order to improve the structure of large NC programs, use the
control's structuring function
Use the control's commenting function in order to document
NC programs
When machining holes and simple pocket geometries, use the
comprehensive cycles available in the control
Further information:
For fits, output the contours with RL/RR tool radius
compensation. This makes it easy for the machine operator to
make necessary compensations
Separate feed rates for pre-positioning, machining, and
downfeeds, and define them via Q parameters at the beginning
of the program
Example: Variable feed rate definitions
1 Q50 = 7500 ; POSITION FEED RATE
2 Q51 = 750 ; FEED RATE FOR PLUNGING
3 Q52 = 1350 ; FEED RATE FOR MILLING
