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.

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.
