Special Canned Cycle
Special canned cycle includes commands G34, G35, G36 and G37.
Unit:
- Unit of length: millimeter (mm)
- Unit of angle: degree
Special canned cycle commands (G34~G37) must be used together with standard canned cycle commands (G73~G89).
When the execution of a special canned cycle command is finished, the standard canned cycle command remains effective until it is canceled.
Example:
G81 Z-20 R-5 F100 K0 'specify the cycle action
G34 X10 Y10 I10 J90 K10 'drill 10 holes around a circle
X100 'drill another hole, not influenced by the previous G34
If there is no standard canned cycle command when a special canned cycle command is executed, the system will report an error.
Eg: when the following commands are executed, an error prompt will pop up.
Command G34/G35/G36/G37 error: special canned cycle instructions do not match, with no designation.
G0 X0 Y0 Z0
G34 X10 Y10 I10 J90 K10
...
A correct form of the command should be like:
G0 X0 Y0 Z0
G81 Z-20 R-5 F100 K0
G34 X10 Y10 I10 J90 K10
