Study on Cutting Mechanism and Cutting Performance of Inclined Surface Machining with Radius End Mill

—Comparison with Cutting Method of Contouring Path and Scanning Path—

抄録

This paper deals with an analysis of the cross-sectional chip area and cutting performance of radius end milling of an inclined surface using a contouring and scanning cutter path method. At first, the modeling of a cutter, an edge, a rake surface and a workpiece with an inclined surface are carried out using 3D-CAD. Secondly, the cross-sectional chip area is calculated by the interference of the rake surface and the uncut chip volume. The influence of the cutting method and the direction of pick feed on the behavior of the cross-sectional chip area. And also, the influence of the inclination angle of the machined surface on the maximum cross-sectional chip area is shown. In addition, the cutting force and surface roughness are measured by cutting tests and the cutting processes are examined. Finally, cutting conditions which would produce a good cutting performance are considered.
