Round/Chamfer
Corner Rounding
Corner rounding permits the operator to blend the intersection of
consecutive moves.
To activate corner rounding, the operator keys a radius value (positive)
into the CornerRad field of the first move. When the program runs, it
blends the endpoint of the first move with the starting point of the
second. The blend starts where the radius is tangent to the first move,
and extends to where the radius is tangent to the second.
You can use corner rounding at the intersection of non-tangent
line-line, line-arc, arc-line, and arc-arc moves (provided a blend radius
or chamfer is possible). You cannot blend radii at the intersection of a
line tangent to an arc.
Corner rounding can be used to blend inside or outside radii. Tool
diameter compensation can be active during corner rounding. When
you blend inside radii with diameter compensation active, the blend
radius must be greater than the tool radius.
 G-code format: G59
Line-to-Line Corner Rounding
 When the first move contains a CornerRad value, the CNC
automatically finds the radius center and the tangent points
necessary to calculate the tool path. The resulting tool path follows
the solid line.
