WIDG and DIAG (groove width and groove depth)
The parameters groove width (WIDG) and groove depth (DIAG) are used to define the form
of the groove. In its calculation, the cycle always assumes the point programmed under SPD
and SPL.
If the groove width is larger than that of the active tool, the width is removed in several steps.
When doing so, the whole width is distributed by the cycle equally. The maximum infeed is
95% of the tool width after deduction of the cutting edge radii. This provides a cutting
overlap.
If the programmed groove width is smaller than the real tool width, the error message 61602
"Tool width defined incorrectly" and machining is aborted. The alarm will also appear if a
cutting edge width equal to zero is detected in the cycle.

STA1 (angle)
Use the STA1 parameter to program the angle of the oblique line at which the groove is to
be machined. The angle can assume values between 0 and 180 degrees and always refers
to the longitudinal axis.
