11. CONTROL FUNCTION
1 The multiple–workpiece skip function is an option.
2 It is necessary to specify the retrace function option simultaneously with the multiple–workpiece
machining function. Refer to the applicable Descriptions of the retrace function.
1 A skip does not occur during trial multiple–workpiece machining (when the setting of
multiple–workpiece machining is 1).
2 The multiple–workpiece skip signal can be detected only during a re–forward movement. The
skip signal cannot be detected during a forward or backward movement.
3 If the multiple–workpiece machining skip signal is input for a certain block, the machining moves
to the end of that block and stops there. A skip occurs when machining is restarted.
4 If a re–forward movement is stopped by feed hold, and the multiple–workpiece machining skip
signal is input for a certain block, then machining is restarted, the machine moves to the end
of that block and stops there. A skip occurs when machining is restarted.
5 When a multiple–workpiece machining skip occurs, a backward movement for the skipped
workpiece becomes impossible. If a backward movement is attempted for the next workpiece,
the backward movement ends at the skipped position.
6 When a multiple–workpiece machining skip occurs, the following information is re–set to the
state in which it was when multiple–workpiece machining was started.
1) Absolute/incremental (G90/G91)
2) Cutter compensation mode (G40/G41/G42)
3) Plane selection (G17/G18/G19)
4) Programming data input (G10/G11)
5) Inch/metric input (G20/G21)
6) Stored stroke limit (G22/G23)
7) Punch/laser mode
8) Forming mode/cancel
9) Workpiece clamp/unclamp
10) Nibbling mode/cancel
Basically, the modes mentioned above must be canceled for a multiple–workpiece machining
7 The multiple–workpiece machining function cannot be used together with:
1) Coordinate system rotation
3) Advance T–code specification
