立体カムの輪郭制御

抄録

This study concerns to the determination of the path of a cutter with a smaller or larger diameter than the cam follower for milling of cylindrical cam such, as an index barrel cam, cylindrical grooved cam or end cam. There are many reasons why a full size cutter (where the diameter of the cutter is the same as that of the cam follower) is not used during processing of a cam. Errors are unavoidable when the diameter of the cutter is not same as the full-size cutter. The errors are influenced by the ratio of the diameter of cutter to that of the follower, the stroke of the follower member and the size of the cam, for example. This study shows the contribution of each of those factors to the errors and presents a guideline for the selection of the size of the cutter. Furthermore, this study shows the nature of the error depending on the longitudinal location of the cam follower.
