Investigation of Cutting Temperature on Machining Titanium Alloys Using Micro-textured Cutting Inserts

In the current investigation, it was focused mainly to compare and evaluate the analytical and experimental trials on the cutting temperature in machining the titanium alloy using micro-hole textured cutting inserts. Initially, the main input parameters such as cutting speed, depth of cut, and feed rate have been used to evaluate the performances. Box–Behnken technique of response surface methodology was used to perform machining experiments. Secondly, with the help of width of cut and thickness of the chip formed at each trial, the analytical calculation of cutting temperature at the two-deformation zone, namely primary and secondary of the orthogonal cutting, has been done. The efficacy of the input parameters on cutting temperatures has been also compared with the analytical calculation. Importance of the cutting parameters was studied with the help of mean effective plots. Results also revealed that the deviation of cutting temperature between the numerical and experimental investigation was only 13%. This depicts the analytical formulation which was much close relation to that of machined trials of cutting temperatures. Further, the cutting temperatures are found to be minimized at lower feed rates and cutting speed using the observation of mean effect plots.
