6.1.3 IMachine parameters for variable contour pockets
Function Parameter
No.
Entry value
Machining of variable contour
pocket
Direction for pre-milling of
contour
241 0 g Pre-milling of contour

Pockets clockwise, Islands counter-clockwise
add to current entry value:
Sequence: clearing and
+ 2 4 clearing prior to pre-milling of contour
pre-milling of contour
otherwise pre-milling first.
Combining of contours
+ 4 p uncorrected contours are combined
Combining corrected or uncorrected contours
Depending on the entry value contours are combined differently.
Example:
Two pockets intersect each other lightly
With cycles for the milling of pockets with variable
contours, the corrected contours are combined.
The control clears the pockets separately, since the
corrected contours (the paths of the tool-centrepoint)
I,
L----l L----A
do not intersect. Material remains on the inner corners.
With cycles for the milling of pockets with variable
contours, the uncorrected contours are combined.
The control clears the pockets together, since the
uncorrected contours are combined and the uncorrected
contours intersect. No material remains at the inner
corners. In order to combine the uncorrected contours,
the control needs more calculating time than when
combining corrected contours.
Note:
There may be cases, above all in Q-parameter programs, in which the combining of uncorrected contours
can lead to undesirable results.
Note:
If the milling of the channel takes place after roughing out (contour pre-milling), this is only possible with
a double flute mill. Roughing out does not commence at the pilot drill locations.
