Guidelines for Using Chamfers and Corner Radius
If the control is executing in single block mode, the control will enter
the cycle stop state after executing the first block and the adjacent
chamfer or corner radius.
If non-motion blocks are programmed separating the two intersecting
blocks for the corner radius and chamfer features, the control will
execute the chamfer or radius immediately after the first block. The
non-motion blocks are executed after the control has executed the
chamfer or radius.
Any negative signs programmed with the ,C or ,R words are ignored.
The absolute value of the word is used to cut the chamfer or radius. For
example ,C-10 is used as ,C10.
An error is generated if the length of a chamfer is larger than the
programmed length of the first or second move, or for corner rounding
if the programmed corner radius is so large that the tangent point on
both of the two programmed blocks does not exist.
