Programming and Operating Manual (Milling)

The basic sizes for the length and width (_AP1 and _AP2) are programmed without sign and their symmetrical positions
around the pocket center point are computed in the cycle. You define the part of the pocket which is no longer to be
machined by solid machining. The blank dimension for the depth (_AD) is also programmed without sign and taken into
account by the reference plane in the direction of the pocket depth.
The depth infeed when taking into account blank dimensions is carried out according to the programmed type (helical path,
reciprocating, vertically). If the cycle detects that there is space enough in the pocket center because of the given blank
contour and the radius of the active tool, the infeed is carried out vertically to the pocket center point as long as it is possible
in order not to traverse extensive insertion paths in the open.
Solid machining of the pocket is carried out starting from the top downwards.
Explanation of the parameters
For an explanation of the parameters _RTP, _RFP, and _SDIS, refer to Section "Drilling, centering - CYCLE81 (Page 126)".
For an explanation of the _DP parameter, refer to Section "Long holes located on a circle - LONGHOLE (Page 184)".
_LENG, _WID and _CRAD (pocket length, pocket width and corner radius)
Use the parameters _LENG, _WID and _CRAD to define the form of a pocket in the plane.
If you cannot traverse the programmed corner radius with the active tool since its radius is larger, then the corner radius of
the machine pocket corresponds to the tool radius.
If the milling tool radius is larger than half of the length or width of the pocket, then the cycle will be aborted and alarm 61105
"Cutter radius too large" is output.
