Scratch-forming processes of a V-shaped groove onto a perfectly plastic semi-infinite body using an inclined wedge-and abacus' bead-shaped rigid body are analyzed by a minimum energy method. The results on the scratching forces and the shape of piled-up surface of specimen coincide with the experimental results obtained with work-hardened copper specimens. The case of the unlubricated rigid body having a large angle, i.e, 130°, is an exception, where thin burr is formed.
The coincidence between theory and experiment in the V groove rolling is good, where the normal force to the specimen surface is remarkably higher and the pile or heap is wider and lower than those of scratching. The variation of groove width due to the stick-slip in the chipless grating or ruling process is discussed on the basis of the above results.
