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.
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.
Note
For transverse grooving, STA1 is usually 90 degrees.
ANG1 and ANG2 (flank angle)
Asymmetric grooves can be described by flank angles specified separately. The angles can assume values between 0 and
89.999 degrees.
