Experimental Study on the Effect of Cutting Parameters on the Cutting Force of Turning 12L14 Steel
The orthogonal experiment of turning 12L14 free-cutting steel with cemented carbide tool was car-ried out to study the influence of cutting depth(ap),feed rate(f)and cutting speed(vc)on the cutting force.The results show that when turning 12L14 free-cutting steel with cemented carbide tool,the cutting depth has the greatest influence on cutting force,followed by feed rate,and the influence of cutting speed is the smallest.The change of cutting force in each direction increases linearly with the increase of ap and f,and fluctuates with the increase of vc;the relationship between the cutting force and the cutting parameters was analyzed by multiple lin-ear regression,thus the empirical formula of cutting force was established.The effectiveness of the empirical for-mula under a certain parameter threshold was verified by experimental data.
