Real-Time Model Reference Adaptive Control of 3-D Sculptured Surface Machining

The paper deals with a new method for the productive machining of molds and dies which have an artistic geometry characterized by sculptured surfaces. The method developed is referred to as a “Real Time Model Reference Adaptive Control” which autonomously adjusts the optimal feedrate such that the material removal should always be maximized with respect to the capability of a given tool and a given geometry of a workpiece by using a real time simulation of a software-based cutting process model. The practical feasibility of the proposed scheme has been verified through experiments performed on the prototyped system.
