Essay

The object of studies - process of mechanical working the parts from brass, which is based on using of the heat generation under dry friction between the instrument and workpiece. The aim of studies had been the increasing of efficiency of using an energy in the round-robin repeat technological process of formation parts. The main methods of studies were mathematical modelling, experimental studies with the automatically hardware check of parameters of formation, accuracy study and wearout of instrument. Use lathe and drilling mashines which were special equipped, microscope, hardness measurer, microhardness measurer, personal computer equipped with a special additional electronic plate. Studies have shown that in the round-robin process of free formation the using energy gets to 95% from which is generated on the working surface. Studied wear-out of instrument and dependency between sizes of billet and component. Executed industrial approbation of the investigated process, which is recommened to use i n agricultural machine building, devices building and in other branches.
