10.5 Rotatable tool
Figure 10-7
Example: Circular interpolation
In circular interpolation mode, particularly when path segmentation is active, the tool axes
rotate along a path tangentially aligned to the programmed path axes in each sub-block.
Programming example:
:
:
N2 TANG (C, X, Y, 1, "B")
N5 G0 F60 X10 Y10
N8 TRAILON (C1, C, 1)
N9 TANGON (C, -90)
N10 G02 X30 Y30 I20 J0 SPN=2 PON
N15 G0 X70 Y10 SPOF

Illustration of programming example in XY plane
; Define master and slave axes, C
is slave axis for X and Y in the
base coordinate system
; Start position
; Activate coupled motion of
rotatable tool axes C/C1 for
punch and die.
; Activate tangential control with
offset 270°
; Circular interpolation with path
segmentation, 2 strokes are
executed with 270° offset angle
and tangential alignment along
circular path
