BASIC CONDITIONS OF PROPER PART SURFACE GENERATING WHILE MACHINING ON CONVENTIONAL MACHINE TOOL

Machining of the part surface on the conventional machine tool sometimes presents geometrical problems that are not envisioned in classical geometry of surfaces. This paper presents definition and illustration of the basic conditions of proper part surface generating while machining on conventional machine tool, i.e. on turning machine tool, on milling machine tool, on machine tool for gear manufacturing operations etc. This result is significant for it substantiates earlier works in planning of part surface machining operations. From a theoretical viewpoint, it is remarkable that one can analytically describe all basic geometrical conditions that are necessary for proper part surface generating while machining on conventional machine tool. It also offers simple practical means of part surface generating without undercutting and overcutting, but within the given tolerance on the part surface accuracy.
