Cycle process:
1. G22 defines the starting of cycle body and L defines the cycle times.
2. Execute the cycle body program.
3. Cycle times L subtracts 1 when G80 cycle body ends. Execute the cycle body program
again when L ≠ 0
；
when L=0 , the cycle ends and the following program is executed.

N0030 G03 W-14.28 R10 ； X, Z executes the tool infeed, cutting concave arc
N0040 G01 W14.28 F500
；
Z executes the tool retraction to starting point of arc
N0050 G80 ； end of cycle body
Note 1:
Programming according to the actual shape in the above-mentioned examples. Fig. 30a:
its programming can be used for the rough machining including smithing and moulding,
which can improve the machining efficiency. Fig. 30b: it can be used for machining the
rod.
Note 2:
When executing the part cycle command, the cycle command G90, G92, G94, G71, G72
are not embedded
