Abstract

The present disclosure includes a generalized kinematics library (210) which may be used to control the motion of a machine tool system (100) and to process data for other applications, such as simulation graphics (245). Methods are disclosed to interpolate the movement of various axes of a machine tool system (100) through a machine singularity point (490).
