Special Canned Cycle
Description:
Unit of length: millimeter (mm)
Unit of angle: degree
1 meter=1000mm, one full circle= 360 degrees

instruction remains effective until canceled.
For Example:
G81 Z-20 R-5 F100 K0 ’specifying the cycle action
G34 X10 Y10 I10 J90 K10 ’drilling10 holes around a circle
X100 ’drilling another hole, not influenced by the previous G34

G0 X0 Y0 Z0
G81 Z-20 R-5 F100 K0
G34 X10 Y10 I10 J90 K10
