DIN/ISO: G231)
Cycle run
1 From the current position, the TNC positions the tool in a linear 3-D
movement to the starting point
1 .
2 The tool subsequently advances to the stopping point 2 at the feed
rate for milling.
3 From this point, the tool moves at rapid traverse FMAX by the tool
diameter in the positive tool axis direction, and then back to
starting point
1 .
4 At the starting point 1 the TNC moves the tool back to the last
traversed Z value.
5 Then the TNC moves the tool in all three axes from point 1 in the
direction of point 4 to the next line.
6 From this point, the tool moves to the stopping point on this pass.
The TNC calculates the end point from point
2 and a movement in
the direction of point 3 .
7 Multipass milling is repeated until the programmed surface has
been completed.
8 At the end of the cycle, the tool is positioned above the highest
programmed point in the spindle axis, offset by the tool diameter.
