Finishing cycle run
1 The TNC runs the 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 a safe position with
radius compensation R0 before the cycle call.
The tool position at cycle call (cycle starting point)
affects the area to be machined.
The TNC takes the cutting geometry of the tool into
account to prevent damage to contour elements.
If complete machining with the active tool is not
possible, a warning is output by the TNC.
Also refer to the fundamentals of turning cycles (see
page 307).
