Optimization of cutting parameters based on toolchip interface temperature in turning process using Taguchi’s method

Determination of optimal machining parameters is continuous engineering task which goals are to reduce the production costs and to achieve the desired product quality. This paper discusses the use of Taguchi’s method for optimizing the cutting parameters in turning for minimizing the tool-chip interface temperature. The cutting temperature is a key factor which directly affects cutting tool wear, workpiece surface integrity and machining precision. In this research work the tool-chip interface temperature is measured experimentally during turning of Č1730 (EN C60) steel with cemented carbide inserts using a tool-work thermocouple technique. The study shows that the Taguchi method is suitable for optimizing the cutting parameters with the minimum number of experiments. From the analysis using Taguchi’s method, results indicate that among the all-significant parameters, cutting speed is the most significant parameter. Results obtained from Taguchi method closely match with ANOVA.
