Temperature rise at chip during machining leads to formation of built up edge, reduced tool life and poor surface finish. In this paper, one of the author’s coding at MATLAB® is modified with small changes to determine temperature rise distribution at chip side due to primary deformation zone. The modified coding is a simplified program of an analytical model, linked with basic machining parameters and is expected to obtain temperature rise contour in few seconds during starting of turning operation. The modified coding is validated using already obtained results of scientists. The developed coding is used for EN31 Steel when turned with MTCVD coated carbide inserts. The work is carried out with number of turning operations on DRO lathe machine. Dynamometer & Digital Vernier are used as accessories to measure developed forces during machining & chip thickness respectively during each operation. The machining data is collected and is used to generate temperature rise contour graphs for every experiment from developed coding. A study of variation of developed forces & maximum temperature rise at chip during machining has also been done with respect to cutting parameters. It was seen that cutting parameters are directly proportional to developed forces and temperature rise during machining. Influence of Cutting Velocity is most and Depth of Cut is least in varying the forces and temperature rise.
