Abstract
A process of machining a scroll member of a scroll compressor by using a non-rotary cutting tool. The non-rotary cutting tool is to be moved relative to a workpiece in a predetermined direction for cutting the workpiece, with its rake face being held substantially perpendicular to the predetermined direction. The cutting tool includes (a) a generally cylindrical shank portion, and (b) a generally semi-cylindrical body portion which has an outer circumferential surface constituted by the rake face and a semi-cylindrical surface. The semi-cylindrical body portion has a cutting edge which is defined by an edge of the rake face and which is covered with a diamond coating.

A process of machining a scroll member of a scroll compressor which has a base plate and a scroll wall extending from the base plate in a direction substantially perpendicular to the base plate, by using a non-rotary cutting tool comprising (a) a generally cylindrical shank portion, and (b) a generally semi-cylindrical body portion which is coaxial with said cylindrical shank portion and which has an outer circumferential surface constituted by a rake face and a semi-cylindrical surface, wherein said semi-cylindrical body portion has a cutting edge which is defined by an edge of said rake face and which is covered with a diamond coating,
- said process comprising:
- a step of moving at least one of said non-rotary cutting tool and said scroll member relative to the other in such a direction that permits the scroll wall and the base plate to be machined by said cutting edge, while holding said rake face substantially perpendicular to said direction.
