Computer-Aided Tool Selection System Based on Solid Model

Computer-aided tool selection (CATS) is one of CAPP system functions and plays a very important role in metal removal processes. As the geometry of free-form surfaces varies significantly, it is difficult to infer any rules or equations to determine the optimum cutting tools. The methods, which realize the automatic selection of cutting tools in three steps, i.e. roughing, semi-roughing and finishing, during metal removal processes, were discussed based on solid models in specific optimization objectives, and a mathematical optimization model of cutting tools selection for rough cut was built. All proposed algorithms were implemented under UG/Open API environments, and an example case was given to show their feasibility and validity.
