PROGRAMMING
Machining possibilities with R29
L95 Stock Removal with Back Pockets
L96 Stock Removal without Back Pockets
Machining can be programmed longitudinal, on face,
inside, outside.
For L95 max. 10 back pockets (in machining direc-
tion decreasing diameters) may be programmed.
The first contour point will be determined in the
circle. The contour draft has to be described in a
subroutine (G1, G2, G3).
The last point in the subroutine determines the start
diameter of the roughing sequence. For face opera-
tion this point must be the highest point in X, for
longitudinal operation this must be the lowest point in
Z.
The first block in the subroutine must be programmed
in absolute coordinates.
Programming the parameter:
R20 Selection of the desired contour (subroutine
number)
R21 Start point of the contour in X
R22 Start point of the contour in Z
R24 Finishing offset in X
R25 Finishing offset in Z
R24 and R25 are valid for roughing and finish-
ing, with R24=0 and R25=0 the finish dimen-
sion will be reached
R26 Roughing infeed (X or Z), will be omitted with
finishing
R27 Selection cutter radius compensation (40, 41,
42), the control activates the cutter radius
compensation automatically, correct selection
and deselection automatically
R28 Feed
R29 Machining procedure, see table
R30 Feed factor with back pockets
With this number (e.g.: 0,7) the feed will be
multiplied for dive in movements with back
pockets (feed reduction)
