Abstract

Abstract This paper presents new methods of offset surface generation and milling tool selection. Firstly the calculation of a workpiece's area cut by a tool is done by detecting contact points between the tool and the workpiece in a lattice space model. Secondly the tool selection is made by Genetic Algorithm to minimize the total machining time and the uncut area. A tool set is coded as a binary bit string. It is assumed the tools would be used in the descent order of radius and cut their corresponding area as entirely as possible. Simulations and conclusions are briefly described.
