Thus, the measurement of this heat in terms of temperature becomes a necessity for achieving favourable machining performances. Therefore, this work presents a novel study on temperature measurement in three different zones during hard turning operation of 4340 grade steel under pulsating MQL environment. Temperatures are measured at three different locations namely chip-tool interface, flank face, and machined work surface (near to tool-work contact) and the location wise temperature is termed as chip tool interface temperature (T), flank face temperature (Tf) and machined work surface temperature (Tw) correspondingly. The temperature T and Tf are measured with help of K-type thermocouple while Tw is measured by Fluke make infra-red thermal camera. Pulsating MQL significantly reduced the temperature as the maximum temperature is noticed 110 °C which co...

Quadratic regression methodology has been introduced and their performances are compared on basis of mean error percentage among experimental and expected data. Normal probability plots are developed to understand the distribution of result data. ANOVA is implemented for all responses showing significant established regression models at 95 % of the level of confidence. 3D surface graph indicates that the feed is the most dominant term for Ra while cutting speed was more dominant for T and VBc.
