OPTIMIZATION OF PROCESS PARAMETERS USING AHP AND VIKOR WHEN TURNING AISI 1040 STEEL WITH COATED TOOLS

In our previous work, optimal machining parameter selection during turning of AISI 1040 steel using coated tools with the help of Taguchi Method as well as the use of MCDM techniques TOPSIS with AHP were discussed. The disadvantage of Taguchi Method and the advantage of MCDM technique i.e. TOPSIS with AHP were demonstrated and optimal parameter selection was done. In the current work, MCDM technique VIKOR in combination with AHP is used to optimize machining parameters. It was found that the result is in good agreement with that obtained when using TOPSIS with AHP for the same. The current article demonstrates the application of VIKOR with AHP using CVD coated cutting tool data. The same was applied for the data obtained using PVD coated tool.
