This activity concerns development of a nonlinear adaptive controller for a cutting process. The objective is to control the feed rate such that it is optimized without exceeding the permitted maximum torque acting on the tool. Most control systems currently available are simple and follow conservative strategies. In the current project we pursue various nonlinear adaptive control strategies for high performance control of the process. The controllers are designed to perform well for arbitrary combinations of material, type of tool, tool wear, depth of cut, and tool speed. The project is carried out in collaboration with Division of Manufacturing Engineering, Luleå University of Technology. This division has at its disposal a machining center with modified control hardware which is used for practical experiments. A nonlinear adaptive controller has been designed and various tests and fine tunings have been carried out. Practical experiments have demonstrated a promising performance for cutting in aluminum. In the forthcoming year we will explore the performance of the controller for other tools and materials.
