High-speed Milling Aluminum Alloy Cutting Temperature

As the theory foundation of the high-speed cutting (HSC), the research of the mechanism of HSC is the foundation of the application and development of the HSC technology. In the research of the mechanism of the HSC, the cutting temperature is very important, the distribution and the change rule of the cutting temperature is one of the mostly gist of the techniques analysis in HSC. The high-speed milling (HSM) of aluminum-alloys is one of the important applied fields of the HSM technology, this paper does some research work of the cutting temperature of the HSM of aluminum-alloys. By use semi-artificial thermocouple method which nipping metal thread in work piece to measure its temperature, did some experimental researches of the change rule of the cutting temperature which following the cutting parameter; In allusion to the machining characteristic of the HSM, established theoretical model of the work piece temperature field by using the method of heat source; Used the software ANSYS to carry out the finite element simulation analysis of the cutting temperature field of the work piece; The comparison of the results of the theoretical model and the finite element simulation and the data of the experiment showed that they had good concordance.
