Abstract
A method of forming a groove in an essentially planar face of a metal object, the groove being uniformly curved on an arc of radius 'r', and being of a width 'w' and a constant depth 'd'. Such grooves must be formed, for example, to receive the end face seals of the piston of a rotary engine of the trochoidal type. The groove is cut with a broach which is uniformly curved on an arc of said radius 'r', by producing relative motion of the broach and the object about an axis which is the center of a circle of said radius 'r', in such manner that the teeth of the broach cut the groove.
