Cutting time based performance investigation of C & L shaped Die (D3) steel workpiece using CNC vertical milling machine

mechnical engineering in production

High precision machining is possible in the present era because of computer numeric controlled (CNC) machining processes like CNC turning, CNC milling, CNC drilling and many more. In today’s competitive market, all industrialists are tending towards upgraded technologies. CNC is stepping ahead for keeping pace in this competitive era. Mass production with customer’s satisfaction has become a need of today’s customized market which is also the ultimate goal of ‘Make In India’ initiative as started by Govt. of India in the past few years. In the present research study, CNC milling machining was adopted to optimize the selective process parameters for machining of high strength Die steel (D3) workpiece. In the present study, three process parameters were selected, i.e. feed, spindle speed and depth of cut followed by response parameter i.e. Cutting Time (CT). Three levels of each cutting parameter were chosen. Design of experiment (DOE) was applied to find the minimum tests for this research study resulting in nine experimental runs as per L9 orthogonal array (OA). Furthermore, Signal to noise (S/N) ratio analysis, analysis of variance (ANOVA), Contour & Interaction plots analysis etc. are used to analyze the results of experimentation. Regression Modeling is also used in the present research to predict the linear regression equation for the response parameter. An optimal solution is generated for a single and Multi response variable both. This study will be beneficial for researchers and industrialists working in this field.
