摘要： A method of machining seats of a compressor piston having an approximately hemispherical recess. A surface of a piston extending perpendicular to an axis of the piston is machined by annularly moving a cutting element while the cutting element is rotated with respect to the piston to form an annularly cut portion. The surface is further machined by moving the same cutting element in a direction toward the surface while the cutting element and the piston are relatively rotated to form a hemispherical recess in the surface. The firstly formed annularly cut portion becomes an annular chamfered portion on the periphery of the hemispherical recess. In this way, it is possible to form the hemispherical recess, and the annular chamfered portion on the periphery thereof, with the common cutting tool.
