Fixed Cycles: Contour Pocket | THREE-D CONT. TRAIN (Cycle 276, DIN/ISO: G276)
Danger of collision!
If you set the parameter posAfterContPocket to
ToolAxClearanceHeight, the TNC positions the tool after the end
of the cycle only in the tool axis direction to the clearance height.
The TNC does not position the tool in the working plane.
After the end of the cycle, position the tool with all
coordinates of the working plane, e.g.
After the cycle, program the absolute position (not an
incremental traversing movement)
Danger of collision!
A collision may occur if you position the tool behind an obstacle
before the cycle is called.
Position the tool such that the TNC can approach the starting
point of the contour without collision.
If the position of the tool is below the clearance height when
the cycle is called, the TNC issues an error message.
