Function description:
1) The position of thee cutting start (A1) should be specified before grooving cycle, or else the system takes
current point as the cutting start.
2) In the first grooving cycle, the tool isn’t retreated in axial direction when cut to the groove
bottom (B1)
3) If Z/W isn’t specified or movement is 0, the system considers Q(Δk) as 0 no matter whether
Q(Δk) is specified. In this case, only X axis acts and cuts to groove end, and the tool isn’t
retreated in axial direction.
4) Pecking style tool feeding cycle
B1 end point A1 start point
Related parameters and notice:
1) If e is 0, the system doesn’t have radial tool retreating action.
2) The system reports error if X/U isn’t specified or the movement is 0.
3) If Δi is 0 or larger than entire groove depth (U/2), the system reports error.
4) The system reports error if Z/W is specified but Δk is larger than z axis movement
(W). If Δk is 0, it can be used for radial cycle drilling
5) If Δd is 0, the tool isn’t retreated in axial direction; if Δd is larger than Δk, the
system reports error.
