Abstract:

A method combining experimental analysis and empirical modeling was introduced to manifest the mechanism of cutting forces obtained from high speed cutting aluminum alloy using carbide end mill. Especially, the influence disciplinarian of cutting parameters on cutting forces was focused on. Meanwhile, the force relationship between time domain and frequency domain on different machining speed was proclaimed, which will be helpful to find the effect rule of forces on cutting mechanism, surface quality and cutting efficiency. A empirical cutting force model of 7075 aluminum was built up. The empirical force model was validated accurate and reliable comparing to milling
force experiments, so the cutting forces can be predicted effectively. 
