1.8.1 Programming example
Canned cycles (·M· model)
To machine a 80x40 pocket centered at (X60, Y35) and rotated 15º. The pocket surface is
at Z0 and it is to be emptied down to Z-20. The reference plane is at Z2.

The penetrating pass is 5 mm and it is carried out at a feedrate of 50 mm/min.
G87 Z2 I-20 D2 A15 J40 K20 M1 Q10 B5 ····· V50
The milling is carried out with a 5 mm wide roughing pass and at a feedrate of 800 mm/min.
Since the milling feedrate must be selected before the execution of the cycle, it is defined
in the previous block.
