Line with radius G87
G87 machines transition radii at orthogonal, paraxial inside and outside

the tool is located at the X or Z coordinate of the corner before the
cycle is executed. The radii are machined in one pass.

orientation" (see “Lathe tools” on page 419).
Tool position at the end of the cycle: End point of radius
