Effect of Varying Surface Grinding Parameters for AISI 1018 Mild Steel by Taguchi based PCA

Anil Sharma, M.K. Gaur, Saurabh Agrawal


The main purpose of this work is to study the effects of surface grinding parameters on AISI 1018 Mild steel work surface by using three process parameters like Wheel speed (WS), Table speed (TS) and Depth of cut (DOC). This work was conducted on surface grinding machine with model number HMT-P452. Taguchi’s L16 orthogonal array is used which takes sixteen experimental runs to achieve the design matrix of surface grinding parameters through Principal component analysis (PCA), utilizing relevant experimental data as obtained through experimentation. Principal component analysis is used as multiple responses optimizing technique to drive optimal solution, which gives the overall quality index in experimental process, and finally result was verified through confirmatory test. Wheel speed, Table speed and Depth of cut are optimized with the consideration of multiple performance characteristics namely Surface roughness Ra (µm) and Material Removal Rate MRR (g/min.). The capabilities of above proposed models have been tested through the analysis of variance (ANOVA).  It was found that Wheel speed (WS) is most significant parameter followed by Depth of cut (DOC) and Table speed (TS).


Key words: CNC Surface grinding, Grinding parameters, AISI 1018 Mild steel, Taguchi Approach, PCA.
