Optimal Selection of Control Factors in Abrasive Water Jet Cutting of Titanium Grade 5

Panchal Vivek Mahendra, Paramjit Thakur, Panchal Deven Ashok, Patil Avishkar Vijay, Shetty Akshay Satish


The Technique for Order Preference by Similarity Ideal Solution (TOPSIS) approach was used to carry out optimization studies on an abrasive water jet (AWJ) cutting process with multiweapon characteristics based on Multi Criteria Decision Making Methodology (MCDM). The process parameters water jet pressure, traverse rate and standoff distance are optimized with multiresponse characteristics, including the depth of penetration (DOP) smooth zone (SR) . The optimized results obtained from this approach indicates that higher DOP and SR were achieved with combinations of the AWJ cutting process parameters, such as water jet pressure of 200MPa, traverse rate of 150mm/min, abrasive and standoff distance of 3 mm. The experimental results indicate that the multiresponse characteristics of the Titanium grade 5 The TOPSIS approach, which is employed during the AWJ cutting process, can be improved. To discover the significant factors for the AWJ cutting process, the effects of input process parameters were analyzed
