G73 Drilling Cycle with Chip Breaking
G73 X- Y- Z- R- Q- <L->
• R - retract position along the Z axis.
• Q - delta increment along the Z axis.
• L - repeat
The G73 cycle is drilling or milling with chip breaking. This cycle takes a Q number which represents a delta increment along
the Z axis.
1. Preliminary motion.
• If the current Z position is below the R position, The Z axis does a rapid move to the R position.
• Move to the X Y coordinates
2. Move the Z-axis only at the current feed rate downward by delta or to the Z position, whichever is less deep.
3. Rapid up a bit.
4. Repeat steps 2 and 3 until the Z position is reached at step 2.
5. The Z axis does a rapid move to the R position.
It is an error if:
• the Q number is negative or zero.
• the R number is not specified
