Chamfering and Corner Radius
Chapter 16
16-4
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 bock to meet
that path. This inserted circular block is always tangent to both
programmed tool paths. If the control cannot generate an arc that is
tangent to both paths with the programmed ,R, then the control generates
an error.
Block: Description:
The first corner radius always terminatesat the point onthe blockwhere therounding block
is tangent tothe first block
The rounding terminates at thepoint where thegenerated roundingblock istangent
to the second rounding block.
The second rounding starts from theend point of thegenerated circular blockand continues
on to the programmed endpoint of the secondblock.
The R-word can be programmed any where in a block as long as no space
is programmed between the ,R and the radius length.
Important: If the two motion blocks are tangent to each other, then any
corner rounding commands are ignored.
