Key Way Cutting Modes
In key way cutting cycles, it is possible to select the cutting direction and cutting method with M
codes.
(1) Selection of cutting direction (M211, M212)
One-directional Cutting Mode (M211)
Cutting in one direction
(2) Selection of infeed mode (M213, M214)
Designated Infeed Mode (M213)
Finish allowance
The tool is infed by the designated amount "D";
in the final cutting path, the depth equivalent
to the fraction is cut.
[Details]
In either cutting mode, the finish allowance U or W is left on the workpiece in the rough cutting cycle;
this finish allowance is finally removed in the finish cutting cycle.
•
Before starting fixed cycle mode operation, the C-axis must be placed in the unclamped (M146)
state.

In the G181 through G184, G189, G190, G178 and G179 modes, the first cycle is executed in
