Abstract Experimental data illustrate how wire electrical discharge machining (EDM) affects the surface roughness of titanium products obtained by powder-based laser surfacing. For samples of VT 20 titanium alloy corresponding to State Standard GOST 19807–91 and VT 20 alloy samples produced by powder-based laser surfacing, the difference in surface roughness is 15%, in fixed electrical discharge machining conditions. The regression equation here proposed permits prediction of the surface roughness in machining workpieces produced by powder-based laser surfacing, taking account of the EDM parameters.

电火花线切割对激光堆焊产品表面粗糙度的影响

摘要 实验数据说明了电火花线切割加工 (EDM) 如何影响通过粉末基激光堆焊获得的钛产品的表面粗糙度。对于符合国家标准GOST 19807-91的VT 20钛合金样品和粉末基激光堆焊生产的VT 20合金样品，在固定放电加工条件下，表面粗糙度相差15%。考虑到 EDM 参数，这里提出的回归方程允许预测由基于粉末的激光表面处理生产的加工工件的表面粗糙度。
