PROGRAMMING5. FEED FUNCTIONS
When cutter compensation is performed, the movement of the nozzle is
automatically decelerated at an inner corner and internal circular area.
This produces a smoothly machined surface.
When G62 is specified, and the nozzle path with cutter compensation
applied forms an inner corner, the feedrate is automatically overridden
at both ends of the corner.
There are four types of inner corners (Fig.18.104.22.168 (a)).

θp is a value set with parameter No. 1711. When θ is approximately
θp, the inner corner is determined with an error of 0.001,or
