This command is Canned Cycle used for drilling cycle with dwell (pause) at the bottom of hole.
Syntax & Parameters
- G82 followed by axis, R, P & F values.
- X, Y, Z, A, B Value - specifies the axis you wish to move following the distance to move. The distance value will be the current machine units in use.
- R Value - This is the retract position in the Z axis. This value must be specified.
- K Value - This is number of time the cycle needs to be repeated. (Optional)
- P Value - This is the dwell (pause) at the bottom of hole. This value is in milliseconds.
- F Value - The F value defines the feed rate at which the axis will move at.

- The first line moves the X & Y axis to 10mm position with retract plane set to 2mm, drilling to Z -8mm with 1 second dwell at bottom of the hole at 100 mm/minute feed rate and starts drilling.
- The K value of 2 will cause the drill cycle to repeat a 2nd time drilling the hole again before moving on to the next line of Gcode.
- The second line moves X axis to 20mm position and drill a hole as per the same values.
- The third line moves X axis to 30mm position and drill a hole as per the same values.
- G80 cancels the canned cycle.
INFORMATION: Units are defined as either inches or mm depending on your machines setup or G20 or G21 command in use.
WARNING: Before a new canned cycle can be used the previous one must be cancelled with a G80
