不同金属材料在磨料水射流加工时的可加工性的试验研究

Experimental Study on Machinability Evaluation of Different Metal Materials Cut by AWJ

通过对磨料水射流切割金属材料过程的能量转移过程的分析,并且将粉碎原理中的比表面能的理论引入切割深度的分析。得出了不同金属材料被切割时由于比表面能的不同,在相同的切割参数的情况下达到相同切割深度时候的切割速度不同。并且通过试验加以验证,同时得出316不锈钢和6061铝合金板材切割时的可加工性特征系数。该系数可以很好的用于磨料水射流切割时候的参数设定。

The crushing principle and theory of specific surface energy was introduced to the analysis of cutting process to predict the depth of cut achievable. The speed was distinct to achieve the same depth in cutting different metal materials with AWJ when cutting parameters are certain. The energy transfer processes in cutting mental materials of AWJ. Machinability characteristic parameter of stainless steel grade 316 and aluminium alloy grade 6061 in AWJ was given ＇after experiments. The specific parameter will be a guidance to set cutting parameters in AWJ.
