Program layout
NC programs should be arranged consistently in a similar manner.
This makes it easier to find your place, accelerates programming
and reduces errors.
Recommended program layout for simple, conventional contour
machining
1 Call tool, define tool axis
2 Retract the tool
3 Pre-position the tool in the working plane near the contour starting
point
4 In the tool axis, position the tool above the workpiece, or
preposition immediately to workpiece depth. If required, switch on
the spindle/coolant
5 Contour approach
6 Contour machining
7 Contour departure
8 Retract the tool, end program

Recommended program layout for simple cycle programs
1 Call tool, define tool axis
2 Retract the tool
3 Define the machining positions
4 Define the fixed cycle
5 Call the cycle, switch on the spindle/coolant
6 Retract the tool, end program
