2.6 Incrementally programmed compensation values
2.6.1 G91 extension
Prerequisites
Incremental programming with G91 is defined such that the compensation value is traversed
additively to the incrementally programmed value when a tool compensation is selected.
Applications
For applications such as scratching, it is necessary only to traverse the path programmed in
the incremental coordinates. The activated tool compensation is not traversed.
Sequence
Selection of a tool compensation with incremental programming
• Scratch workpiece with tool tip.
• Save the actual position in the basic frame (set actual value) after reducing it by the tool
compensation.
• Traverse incrementally from the zero position.
Activation
With setting data:
SD42442 $SC_TOOL_OFFSET_INCR_PROG,
it is possible to define whether a changed tool length is traversed with FRAME and
incremental programming of an axis, or whether only the programmed path is traversed.
Zero offset/frames G91
With setting data:
SD42440 $SC_FRAME_OFFSET_INCR_PROG,
it is possible to define whether a zero offset is traversed as standard with value = 1 with
FRAME and incremental programming of an axis, or whether only the programmed path is
traversed with value = 0.
