Multi-response optimization for laser transmission welding of PMMA to ABS using Taguchi-based TOPSIS method

Recently, the usage of laser transmission welding (LTW) technology in automotive industry has been rising for joining thermoplastic parts regarding its superior properties comparison to other technologies. However, specifying process parameters is a crucial step obtain satisfactory quality vehicle parts. In this context, paper addresses LTW Polimetil metakrilat (PMMA) Akrilonitril bütadien stiren (ABS) materials production taillights an company and proposes new multi-response Taguchi-Based TOPSIS (Technique Order Preference by Similarity Ideal Solution) method optimize machining process. proposed solution methodology, main effects on different outputs are identified using [Formula: see text] orthogonal array Taguchi method. Regarding best parameter set each output, method, which alternatives evaluated through interrelated measures. To taillight production, PMMA ABS samples with dimensions width, length, thickness used experiments. The welded LPKF Twinweld 3D 6000 ® machine. For process, power, speed, pressure force taken into account as input three responses: weld strength, breaking strain, width. identify values, Method initially employed calculate output. Then, carried out evaluate number alternative sets generated results. As consequence ranking scores, that jointly optimizes force. Based conducted experiments, setting achieves highest strain level, above-average results experiments show methodology capable optimizing fewer plastic
