Finishing Cycle Run; Please Note While Programming - HEIDENHAIN TNC 640 User Manual

Cycles: Turning | TURN SHOULDER FACE EXTENDED
(Cycle 822, DIN/ISO: G822)

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 (cycle starting point)
affects the area to be machined.
Also refer to the fundamentals of turning cycles (See
page 374).
