Submerged turning Abrasive water jet Castamid TOPSIS VIKORAbstract
This study focuses on the application of submerged abrasive water jet turning (AWJT) to
enhance the machinability of castamide, a polymer widely used in industrial components. The
research investigates the influence of three primary machining parameters—traverse speed
(TS), abrasive flow rate (AFR), and spindle speed (SS)—each tested at three levels within a
full factorial experimental design. This approach allowed both the independent effects and the
interactions of these parameters to be examined comprehensively. To evaluate process
performance, two responses were selected: surface roughness (Ra), as an indicator of surface
quality, and material removal rate (MRR), representing machining productivity.
The collected data were subjected to statistical analysis using analysis of variance (ANOVA)
and visualized through three-dimensional surface plots to better illustrate parameter
interactions. In addition, multi-criteria decision-making methods, namely TOPSIS and
VIKOR, were applied to determine the optimum machining conditions. Regression models
were also developed to establish predictive relationships between the process variables and
responses.
The results demonstrated that submerged AWJT significantly improved machining outcomes
compared to conventional AWJT. Specifically, the process reduced noise levels from 108.8
dB to 86.1 dB, improved surface roughness by approximately 15%, and resulted in a slight
5.22% reduction in MRR. ANOVA revealed that traverse speed was the most influential
factor, contributing 83.11% to Ra and 85.56% to MRR. Based on the optimization results, the
best machining conditions were obtained at TS = 40 mm/min, AFR = 310 g/min, and SS =
300 rpm. These findings highlight the potential of submerged AWJT as an effective and
environmentally friendly method for machining castamide and similar materials
