Abstract
The aim of the work is to increase the productivity of processing complex-profile surfaces of parts on CNC machines. To achieve this goal, the task of studying the components of cutting forces when processing workpieces with a rotating tool with a steeply inclined cutting edge in various cutting modes is solved. Theoretical and experimental research methods are used. As a result of theoretical research, formulas have been obtained for calculating the normal cutting force when processing a flat surface of a rotating part with an end mill, taking into account the influence of the angle of inclination of the cutting edge and the ratio of the components of the cutting force. The range of change in the angle of inclination of the cutting edge is set, which reduces the cutting force. To verify theoretical dependencies, experimental studies of the components of the cutting force were carried out when processing a billet made of aluminum alloy D16T with end mills from various manufacturers. Using a special software and measuring complex, oscillograms of amplitude changes in the components of the cutting force at different values of cutting depth and embedding, feed to the tooth and cutting speed were obtained. The dependences of the influence of the cutting edge inclination angle on the cutting force are established, confirming the results of theoretical studies. The values of the correction coefficients for the cutting speed are determined, taking into account the angle of inclination of the cutting edge of the tool and the properties of the processed material, which allows to adjust the values of the cutting speed and ensure an increase in processing productivity up to two times.
