3.2.2.45 G115 Convex surface transformation
Convex surface transformation "on" or "off".
G115 X Y Z A B C I
XYZ Selection of lateral and longitudinal axis.
0: lateral axis
≠
0: slope factor of the lateral axis (if programmed)
ABC Selection of the involved rotation axis and radius at the start of the cone
(when the position of the longitudinal axis=0)
I without programmed axes:
0: switch off transformation temporarily
1: switch on transformation with old parameters again
Sheath transformation is a process whereby cartesian coordinates are
represented on a cone surface. The cone is defined via radius and slope. The
cartesian coordinates are transformed during the axis output in coordinates
for a rotation axis and a longitudinal axis. The rotation axis rotates the
workpiece and the longitudinal axis moves the tool along the rotation axis.
The third possible axis, vertically to the workpiece, is not transformed.
To switch the transformation off, G115 must be programmed without
parameters.
When the transformation is switched on, the involved rotation axis can only
still be moved via programming of the lateral axis.
G115 X0 A50 Switch on the sheath transformation with X as the lateral axis, A as the
rotation axis and any longitudinal axis. The radius of the cylinder, on whose
surface the profile is represented, is 50 mm.
