Cutter compensation can be performed only in offset mode. An alarm will occur when this is
attempted in startup or cancel mode.
The setting for [Cutter compensation] is applied to the selected plane during cutter compensation,
relative to the start point and target point specified in the program.
An alarm will occur when the programmed conical interpolation tool path or the tool path after
cutter compensation intersects or makes contact with the conical center.
An alarm will occur when the circular cone defined that over the circle radius fudge factor limit
point by the increment or decrement in radius per rotation does not match the end point.
An alarm will occur when corner CR is specified in the block immediately before a block that
performs conical interpolation.
Automatic corner override is not possible for the blocks immediately before and after a block that
performs conical interpolation.
Corner CR cannot be specified for conical interpolation.
An alarm will occur when the cutter compensation direction (G41, G42) is changed between the
blocks immediately before and after a block that performs conical interpolation.
An alarm will occur when the radius is specified using command "R."
An alarm will occur when the increment or decrement in radius is zero (0).
An alarm will occur when setting value of selected flat as below.
(1)
Start point radius = End point radius
(2)
Start point = Center
(3)
End point = Center
Not commanded when mirror image is effective.
Not commanded when scaling image is effective.
When a cutter compensation cancel command is included in the block immediately after a block
that performs conical interpolation and cutter compensation, the end point of the conical
interpolation will be the position given by the vertical vector from the end point of conical
interpolation on the selected plane.
An in-position check is performed between the blocks immediately before and after a block that
performs conical interpolation.
