Automated selection of cutting tools based on solid models

During the development of automation for metal removal processes, the issue that cutting tools and parameters are selected automatically will be considered first. In traditional NC machining, the selection of cutting tools is based primarily on experience, which is error-prone and insufficient in respect of standardization. In order to eliminate these problems so as to be able to achieve cutting automation, the development of computer-assisted tool selection is needed. This paper proposes a methodology for the automatic selection of cutting tools for various cutting stages, including rough, semi-rough and fine cuts. The methodology starts with analyzing the sectional and volumetric properties of 3D solid model. This geometric information, together with some empirical equations found in tool handbooks, are further applied to determine appropriate tool sizes. Detailed cutting parameters for each cutting tool are also retrieved for practical machining. (C) 1997 Elsevier Science S.A.
