摘要
电解机械复合加工方法进行硬质合金刀具的刃口钝化,可以提高刀具钝化后的刃口均匀性。重点研究了电化学机械复合加工的刃口钝化工艺,通过对电解电压、电解间隙、进给量以及电源频率试验参数进行正交试验,找到了较优的钝化工艺参数。试验表明:影响刃口去除量的最大因素是电解间隙,其次是电解电压;最优的工艺参数组合:电解电压12V,进给量6 mm/min,电源频率6 kHz,电解间隙0.3 mm。
Cutting edge passivation of cemented carbide tool using electrolysis mechanical complex machining methods can improve the tool edge passivation uniformity. Study was focused on the complex electrochemical mechanical machining edge passivation process,and through the electrolysis voltage,electrolytic gap,feed rate,and power frequency test parameters for orthogonal test,parameters were found for optimum passivation process. Tests show electrolysis gap is the biggest factor of impact on edge removal amount,followed by electrolysis voltage. The optimal combination of process parameters is:electrolysis voltage of 12 V,the amount of feed is 6mm/min,power frequency is 6 kHz and electrolysis gap is 0.3 mm.
