CornerRadius
Use the ,R command to program a radius between two intersecting tool
paths. The R command must be programmed after a comma (,). Program
the ,R followed by the radius size in the block where the first path is
programmed. The control looks ahead to the block commanding the
second path, and automatically inserts the circular rounding block to meet
that path. This inserted, circular block is always tangent to both
programmed tool paths. If the c ontrol cannot generate an arc that is
tangent to both paths with the programmed ,R , then the control will
generate an error.
The first corner radius block always terminates at the point on the block
where the rounding block i s tangent to the first block. The rounding block
terminates at the point where the generated rounding block is tangent to the
second rounding block. The second rounding block starts from the
end-point of the generated circular block and continues on to the
programmed e nd-point of the second block.
Important: If the two motion blocks are tangent to each other, then any
corner-rounding commands are ignored.
