Useful configurations for the machine tool operator:
In order to enable a realistic graphic simulation, use 3-D models
in STL format as a workpiece blank and finished part
Further information: "Defining the workpiece blank: BLK FORM",
Page 91
In order to improve the structure of large NC programs, use the
control's structuring function
Further information: "Structuring NC programs", Page 199
Use the control's commenting function in order to document NC
programs
Further information: "Adding comments", Page 195
Use the comprehensive cycles of the control available for the
machining of holes and simple pocket geometries
Further information: User's Manual for Programming of
Machining Cycles
For fits, output the contours with RL/RR tool radius
compensation. This makes it easy for the machine operator to
make necessary compensations
Further information: "Tool compensation", Page 133
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
FEED RATE FOR POSITIONING
2 Q51 = 750
FEED RATE FOR PLUNGING
3 Q52 = 1350
FEED RATE FOR MILLING
