An Analytical Evaluation of Drilling Temperature
An analytical model of drilling temperature was developed based on the thermal model of orthogonal cutting and equivalent model. In this model, the element of cutting edge of twist drill was acted as an independent cutting process. The effects of drilling parameters on the temperature were also investigated. Tests were conducted with various parameters and temperature was measured by manual thermocouple method. Results indicated that the predicted results were according to the measured ones; the errors were less than 15%. And the laws obtained by analytical model were the same as that obtained by tests.
