6. INTERPOLATION FUNCTION
699
(b)Override in the neighborhood of a basic
If a programmed cutting feedrate is directly used in the neighborhood
of a basic circle where the curvature of an involute curve changes
relatively sharply, the cutter may be overloaded, resulting in a failure
to produce a satisfactory cutting surface.
With this function, the movement of the tool is automatically
decelerated according to the setting of a parameter in the neighborhood
of a basic circle where the curvature of an involute curve changes
relatively sharply, so that the load on the cutter is reduced to produce
a satisfactory cutting surface.

This parameter sets the allowable limit of deviation between an involute
curve passing through a start point and an involute curve passing through
an end point for an involute interpolation command.
