ABSTRACT:
In an apparatus for profile grinding a closed curved surface such as a trochoidal curved surface of the type wherein the attitude of a worktable which supports a workpiece is profile controlled in accordance with a master profile corresponding to the closed curved surface to be formed in the workpiece, the axis of a grinding wheel is maintained at a fixed position, a mechanical information is generated by the cooperation of a master cam having a peripheral profile corresponding to the profile of the closed curved surface and a master cam normally urged against the peripheral profile, and the attitude of the worktable is controlled in accordance with the mechanical information. Where a grinding wheel having a diameter different from a predetermined value is used, a primary feed calculated by an equation to be described later is applied to the grinding wheel thus enabling to use a grinding wheel of any diameter.
