Finishing cycle run
1 The TNC runs the paraxial infeed motion at rapid traverse.
2 The TNC finishes the finished part contour (contour starting point
to contour end point) at the defined feed rate Q505.
3 The TNC returns the tool to set-up clearance at the defined feed
rate.
4 The TNC positions the tool back at rapid traverse to the cycle
starting point.
Please note while programming:
Program a positioning block to the starting position with
radius compensation R0 before the cycle call.
The tool position at cycle call defines the size of the area
to be machined (cycle starting point).
Also refer to the fundamentals of turning cycles (see
page 286).
