摘要
采用线切割方法对金属纤维多孔材料进行高精度加工。为保护材料的孔结构在线切割加工过程中免遭破坏,采取用石蜡保护孔隙结构的方法:加工前将孔隙中填充石蜡,石蜡随纤维材料一起进行线切割加工,加工完成后再将石蜡排出。本文详细研究了孔隙中填充石蜡以及排出石蜡工艺,结果表明:实验采用的"填充石蜡-线切割加工-排出石蜡"的方法可较好地在线切割加工过程中保护孔隙结构,加工结束后石蜡可顺利排出,特别适合孔隙度大于80%的金属纤维多孔材料。
The stainless steel fibrous porous materials are processed by Wire cut Electrical Discharge Machining(WEDM).To protect the pore structure of fibrous porous materials during machining,a special process was used:filling pores with paraffin before machining,and removing the paraffin after the machining.The effects of porosity and pore size on the process were studied,the results indicate that the process used is good for protection of porous structure during WEDM,and the porosity and pore size have obvious eff...
