Process planning system of 5-axis machining center considering constraint condition

摘要

This study proposes the method of the process planning for 5-axis machine tools. In our previous study, the process planning, in which the Total Removal Volume is divided by the planes parallel with the XY, YZ or ZX plane to analyze machining sequence from top to bottom of the target product, is proposed. In this study, the process planning system in which the Total Removal Volume is divided by all planes (including slope planes) existing on the target product is proposed. Furthermore, the design constraint or the designer's intention such as discontinuous through holes which have the same central axis is considered in this process planning. A case study was conducted and the result showed that the proposed method can design efficient multiple process plans for the machining operation. These multiple process plans or machining sequences allow users to select adaptively the suitable process plan or machining sequence based on the property of 5-axis machine tool to be used under the design constraint.
