Programming and Operating Manual (Milling)
198 6FC5398-4DP10-0BA1, 01/2014
_AP2 REAL Blank dimension of pocket width
_AD REAL Blank pocket depth dimension from reference plane
_RAD1 REAL Radius of the helical path on insertion (relative to the tool center point path) or
maximum insertion angle for reciprocating motion
_DP1 REAL Insertion depth per 360° revolution on insertion along helical path
The cycle can be used for roughing and finishing. For finishing, a face cutter is required.
The depth infeed will always start at the pocket center point and be performed vertically from there; thus it is practical to
predrill at this position.
● The milling direction can be determined either by using a G command (G2/G3) or from the spindle direction as
synchronous or up-cut milling.
● For solid machining, the maximum infeed width in the plane can be programmed.
● Finishing allowance also for the pocket base
● There are three different insertion strategies:
– vertically to the pocket center
– along a helical path around the pocket center
– oscillating at the pocket central axis
● Shorter approach paths in the plane for finishing
● Consideration of a blank contour in the plane and a blank dimension at the base (optimum machining of preformed
pockets possible).
Sequence
Position reached prior to cycle start:
Starting position is any position from which the pocket center point can be approached at the height of the retraction plane
without collision.
Sequence of motions when roughing:
With G0, the pocket center point is approached at the retraction level, and then, from this position, with G0, too, the
reference plane brought forward by the safety clearance is approached. The machining of the pocket is then carried out
according to the selected insertion strategy, taking into account the programmed blank dimensions.
