Note
If the tool orientation with active ORIAXES is interpolated via the orientation axes, the angle
of rotation is only initiated relative to the path at the end of block.
6.5.4

Smoothing of orientation characteristic (ORIPATHS A8=, B8=, C8=)

Function
Changes of orientation that take place with constant acceleration on the contour can cause
unwanted interruptions to the path motions, particularly at the corner of a contour. The
resulting blip in the orientation characteristic can be smoothed by inserting a separate
intermediate block. If ORIPATHS is active during reorientation, the change in orientation
occurs at a constant acceleration. The tool can be retracted in this phase.
Machine manufacturer
Please refer to the machine manufacturer's notes on any predefined machine and setting
data used to activate this function.
Machine data can be used to set how the retracting vector is interpreted:
1. In the TCS, the Z coordinate is defined by the tool direction.
2. In the WCS, the Z coordinate is defined by the active plane.
