13.7.2 Corner rounding " ,R_ "

Function and purpose
The imaginary corner, which would exist if the corner were not to be rounded, is rounded with the
arc having the radius which is commanded by ",R_" only when configured of linear lines.
Command format
N100 G01 X_ Y_ , R_ ;
N200 G02 X_ Y_ ;
,R_
Corner rounding is performed at the point where N100 and N200 intersect.
Example of program
(1) G91 G01 X100., R10. ;
(2) X100. Y100. ;
Y axis
Detailed description
(1) The start point of the block following the corner R serves as the imaginary corner intersection
point.
(2) When the comma in ",R" is not present, it is handled as an R command.
(3) When both the corner chamfer and corner rounding commands exist in the same block, the
latter command is valid.
(4) Tool offset is calculated for the shape which has already been subjected to corner rounding.
(5) Program error "P381" results when there is an arc command in the block following the corner
rounding block.
(6) Program error "P382" results when the block following the corner rounding block does not
have a linear command.
(7) Program error "P383" results when the movement amount in the corner rounding block is less
than the R value.
(8) Program error "P384" results when the movement amount in the block following the corner
rounding block is less than the R value.
