Abstract

An apparatus for controlling operation of a processing machine has a computer preferably with a computer aided design program configurable to model a kinematic velocity profile of a point of interest on a machine to be controlled. A graphical user interface on the computer enables an operator to select desired velocity points for a motor drive controlling motion of the point on the machine. A curve fit is applied to the velocity points to realize a desired velocity profile for the motor drive and the point on the machine. The desired velocity profile is then integrated and scaled in order to obtain a scaled velocity profile that realizes an actual, or target displacement of the point as dictated by operation of the machine. By controlling operation of elements of a machine with velocity profiles, coordination of associated elements and points on the machine can be visualized by an operator selecting the velocity points for each drive of the machine. A method for implementing same is also disclosed.
