10.3 RULED SURFACE (Cycle 231, DIN/ISO:

G231, software option 19)

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.

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.
