Application of Optimal Control Problem for Surface Roughness Improvement in Milling

Abstract:

This paper presents an improvement of the approach for increasing automation level of CNC machines by using a supervising controller that, for a given toolpath, tool geometry, and workpiece material, calculates the optimal sequence of controls. The developed system, based on three steps: process simulation, solution of the optimal control problem (OCP), and state reconstruction with state learning, is improved while reformulating the OCP by taking into account the surface roughness.
