Ultrasonic elliptical vibration-assisted machining (UEAM) and laser-assisted machining (LAM) are considered as hybrid machining processes, in which 2D ultrasonic vibrations and heat are used to improve metal cutting process; in the present study, a series of experimental tests with the aim of measuring cutting forces and workpiece surface roughness in hybrid laser- and ultrasonic elliptical vibration-assisted machining (HL-UEAM) are conducted to evaluate the effect of process parameters including un-deformed chip temperature, vibration amplitude, work velocity and feed. A statistical analysis has been performed on the data obtained from the experiments, and the main effect of parameters as well as their interaction effects on process outputs is analyzed. The results revealed the reductions of 43, 54 and 75% in the main component of cutting force can be achieved in LAM, UEAM and HL-UEAM compared to conventional turning (CT), respectively. Therefore, from the force reduction perspective, simultaneous application of laser and ultrasonic elliptical vibrations would be more effective than their separate usage. The results of surface roughness measurement declared the approximately 20% increase in surface roughness by UEAM compared to CT. However, HL-UEAM surface roughness measurement shows approximately 35% enhancement compared to CT.

工艺参数对激光和超声椭圆振动混合加工中切削力和表面粗糙度的影响

超声椭圆振动辅助加工(UEAM)和激光辅助加工(LAM)被认为是混合加工工艺,其中二维超声振动和热量被用来改善金属切削工艺。在本研究中,进行了一系列旨在测试混合激光和超声椭圆振动辅助加工(HL-UEAM)中的切削力和工件表面粗糙度的实验测试,以评估包括未变形在内的工艺参数的影响切屑温度,振动幅度,工作速度和进给。对从实验中获得的数据进行了统计分析,并分析了参数的主要作用及其对过程输出的交互作用。结果显示减少了43 与传统车削(CT)相比,LAM,UEAM和HL-UEAM分别可实现切削力的54%和75%。因此,从减小力的角度来看,同时应用激光和超声椭圆振动会比单独使用更为有效。表面粗糙度测量结果表明,与CT相比,UEAM使表面粗糙度提高了约20%。但是,与CT相比,HL-UEAM表面粗糙度测量显示出约35%的增强。表面粗糙度测量结果表明,与CT相比,UEAM使表面粗糙度提高了约20%。但是,与CT相比,HL-UEAM表面粗糙度测量显示出约35%的增强。表面粗糙度测量结果表明,与CT相比,UEAM使表面粗糙度提高了约20%。但是,与CT相比,HL-UEAM表面粗糙度测量显示出约35%的增强。
