Application of AHP as a Decision-Making Tool for Determining the Optimal Surface Grinding Environment
Subscribe/Renew Journal
Surface grinding is an extensively used high speed machining process for smooth finishing. Enormous heat is generated during the process due to high specific force and energy consumption that eventually impairs surface finish and integrity by generating tensile residual stress, forming cracks and burns. To reduce thermal related damages, proper selection of grinding environment is indispensable. In this work, to obtain the best condition and environment among dry and wet grinding using 1:80 and 1:20 coolant concentrations, the analytical hierarchy process (AHP) is applied. In the present analysis, 1:20 coolant concentration with 10 µm infeed is estimated to be the optimal grinding environment for low alloy steel.
