Programming example
Thread without encoder
In this program a thread is tapped without encoder at
position X35 Y35 in the XY plane, the drilling axis is
the Z axis. Parameters SDR and SDAC for the
direction of rotation must be assigned, parameter
ENC is assigned the value 1, the value for the depth
is absolute. Pitch parameter PIT can be omitted. A
compensating chuck is used in machining.
