Claim One:
1. Apparatus for simulation of the mechanical behavior of the mechanism of machine tools or production-line machines having multiple drive controllers for driving multiple axes, said apparatus comprising: a digital controller, said digital controller producing respective desired axis values; an auxiliary computer connected to the digital controller for receiving said desired axis values from the digital controller, said auxiliary computer including mathematical model means for calculating respective actual axis values from said respective desired axis values simultaneously using mathematical models of drive controllers of the respective axes, said mathematical models including models of both regulated and unregulated drive controllers, and using said desired axis values; and mechanism model means for generating a state signal using said actual axis values produced by said mathematical models of said drive controllers of the respective axes, said mechanism model means being connected for receiving said actual axis values from said mathematical model means and for supplying said state signal to said digital controller as feedback, whereby both regulated and unregulated axes of the machine are simulated simultaneously.
