Source abstract
Abstract
Application of the new broaching machine of firm HOFFMANN with CNC on high speeds of cutting is economically profitable. Theoretically and practically it is proved, that at the broaching there is an optimum condition of a zone of cutting at optimum temperature of cutting. At this temperature optimum conditions of formation of required parameters of quality of the processed surface and the minimal values of intensity of wear of the tool are observed. In the article the results of mathematical computer modeling for the decision of a problem of numerical calculation of temperature of cutting, thermal fields and optimum modes of cutting are submitted at broaching of hard machining alloys. The problem of optimization of process of broaching is solved by use of the developed method of high-speed broaching, optimization of its parameters and the tool. As a result, the new method of optimal high-speed broaching is developed. It is proposed to switch the speed of cutting automatically to the optimal value V0 during one working course of the lingering block on various parts of broaches corresponding to constant optimal temperature of cutting on each tooth of the broaches.
