In this study, a commercial CAD/CAM Software is used to plan and generate the multi-axis tool path, and a table rotating/tilting type five-axis machining center is used to perform the experimental machining operation. The material of the die studied is NAK 80 die tool steel, and the geometries are modeled as concave and convex spherical surfaces. Milling parameters considered are spindle speed, feed rate, and different types of cutting tool path. The experimental results show that the surface roughness for concave spherical surface is about 0.247 μm and roundness is about 0.0283 mm and the surface roughness for convex spherical surface is about 0.250 μm and spherical roundness is about 0.0551 mm under the cutting conditions mentioned in this study.

The shapes of the melting solid surface may be concave, convex or plane, while the perimeter of plane contact regions may be rectangular, circular, elliptical, parabolic and arc curve. The types of relative motion reviewed here are the movement of a solid PCM melting inside a heated capsule, the movement of a hot body through a melting solid medium, slide contact and rolling contact. The contact melting may be caused by temperature difference, pressure difference, friction and viscous heating. Finally, the research regions in the future are summarized.
