摘要： An internal grinding method for grinding an inner surface of a work having a straight line generatrix shape while performing an in-process inner-diameter size measurement intermittently through oscillation synchronized between a grindstone and a measurer; wherein a circumferential surface of the grindstone is trued into a shape inclined with respect to a moving direction of a X-axis slide table moving forward/backward relative to the work so that normal grinding force when the X-axis slide table moves backward is reduced, while the work is supported with inclination with respect to the moving direction of the X-axis slide table so that the X-axis slide table is oscillated in the moving direction.

摘要： The inner surface 2a of the input side disk 2 is composed of a near-inside-diameter portion, namely, a first arc surface 16 and a near-outside-diameter portion, namely, a second arc surface 17 in such a manner that the first and second arc surfaces 16 and 17 are allowed to continue with each other smoothly. The first arc surface 16 is formed as a single arc whose radius of curvature is R2a.

The cam disc includes a disc portion having the cam surface formed thereon and a cylindrical portion protruding from the central portion of the cam surface. The cam disc further includes a lathe-turned portion formed by lathe turning, a milled surface formed by means of an end mill, and a ground surface formed by means of a grindstone. Formed on a corner portion between the cylindrical portion and the disc portion are a first corner curved surface worked by means of an arcuate portion on the distal end portion of the end mill and a second corner curved surface worked by means of an arcuate portion on the distal end portion of the grindstone.
