Lessson 3: CNC Canned Cycles, Drilling, Tapping, Reaming and Boring Cycles
Canned cycles are used every time we need to drill, ream or tap holes on our CNC machine
Standard Fanuc G-Code language supports more than a dozen canned cycles.
The most common cycles that will cover 99.9% of your g-Code CNC programming work are:
G-Code | Name | Motion Style |
G81 | Standard Drilling | Feed-In, Rapid-Out |
G83 | Deep Hole Peck Drilling | Incremental Feed-In by Peck Distance, Rapid Out, Repeat |
G84 | Right Hand Tapping | Feed-In,Reverse Spindle, Feed-Out |
G85 | Reaming/Boring | Feed-In, Feed Out |
Subsequent holes
You can drill additional holes After your canned cycle has been initiated.
Any line with X Y position will be treated as another hole position.
Each position can have its own Retract value, feed rate and retract height modifier.
G80 - Canned Cycle Cancel Code
After all the holes of the canned cycle have been drilled, it is required to call G80 code in order to cancel the current cycle.
