Whirling切削機構による表面加工

抄録

Whirling has been applied to manufacturing of worm and ball screws for motion controls. The whirling cut, in which the tool and the workpiece rotate simultaneously with an eccentricity between the centers of the workpiece and the tool rotations, has advantages over the general threading in terms of the tool life, the surface finish and the chips control. Whirling has been used for only machining of the screws so far. However, whirling mechanism is expected to machine the several complicated part shapes with control of the ratio of the spindle speed of tool to that of workpiece. This paper presented a surface texturing to fabricate the controlled geometrical structures on the cylinder surfaces in the whirling with 3 cutting tools. The machining tests were conducted to verify the presented texturing manner.
