he effect of cutting speed on cutting force and surface quality in broaching of aluminum 7075

As a single-pass machining operation, broaching is extensively used to produce simple and complicated profiles with finished surface quality. Broaching is often used for mass production. Since, it is a special manufacturing process, few researches has been reported in this area. In this research, the dynamic effects of cutting forces for different cutting speeds on Aluminum 7075 have been theoretically and experimentally analyzed using MATLAB. Moreover, to make sure of the results, experimental setup has also been designed to investigate the effect of cutting speed on surface quality and cutting force. For this purpose, a servo hydraulic system based on position control has been designed. With the increase of cutting speed from 2 m/min to 8 m/min, an undeniable decrease in cutting force is observable, while the surface quality experiences an interesting increase. It can be concluded that the higher cutting speeds are to be preferred for processing this material. In practice, it is applicable for especially car manufacturing industry to shorten the time and lower the cost of production.
