    Optimization of cutting parameters during turning of 16MnCr5 steel using Taguchi technique
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-03) Agarwal, Swapnil; Rajiv Suman
    The present work concerned an experimental study of turning on 16MnCr5 Steel with the help of two different types of coated carbide insert (TNMG160404 and CNMG120404). The objective was to find the optimum machining parameters viz. cutting speed, feed, and depth of cut so as to minimize the surface roughness of the machined material and maximise material removal rate. Experimental work is carried out with the help of computer numeric control (CNC) lathe machine. Machining is done on a 28mm dia and 150 mm long 16MnCr5 steel rod. After machining material removal rate and surface roughness is measured. CNC turning operation are performed using L9 orthogonal array has been developed between dependent and independent variables with the help of Taguchi Technique. The data was compiled into MINITAB 17 software for analysis. The relationship between the machining parameters and the response variables (surface roughness and material removal rate) were modelled and analysed using Taguchi technique and optimization is done with the help of S/N ratio and by applying ANOVA approach. To get optimised parameters for surface roughness and material removal rate we applied lower-the-better condition for surface roughness and higher-the-better condition for material removal rate in signal-to-noise ration. Analysis of Variance (ANOVA) was used to investigate the significance of these parameters on the response variables. Results showed that feed is the most significant factor affecting the surface roughness for TNMG160404 Insert closely followed by cutting speed and depth of cut, Cutting Speed is the most significant factor affecting the surface roughness for CNMG120404 Insert closely followed by depth of cut and feed and depth of cut is the most significant factor affecting the material removal rate for TNMG160404 and CNMG120404 Insert closely followed by feed and cutting speed The optimum combination of parameters for carrying out the machining were obtained from Taguchi Technique are shown in the results section.
