For diesel engine block at both ends of the surface milling,a strong milling head and a strong milling mechanical slide unit are adopted in this paper to develop a strong portfolio of milling machine tools,which not only meet the high-rigidity large cutting strong milling and face milling of precision,but also greatly enhance the efficiency of the processing.

That not only solves the difficult problems of the distortion existing for a long time, but also makes profitable research in how to improve the adapting ability of the special fixture and obtain the manifest effect under the machining state of heavy-feed, high-speed and heavy-cutting.

This paper mainly researches high speed milling TC4 and discusses the problem about cutting force during the process of high-speed milling.

The influences of cutting speed on cutting forces, surface roughness, surface microstructure, and tool wear have been studied by the experiments.

Indirect measurement of the milling forces based on spindle motor current;

Research on Tool Wear State Recognition Based on Milling Force and Wavelet Neural Network;

Clamping technology optimization of high speed machining of NOMEX honeycomb core based on milling force model;

The milling forces modeling and simulation of ball end milling in high speed machining process are studied.

The complicacy of milling processing and other factors of causing milling forces make it difficulty to establish the prediction model of milling forces.

With the geometry model of the ball end mill, the method of theoretic cutting force analysis combined with the identification of the experimental coefficients of milling forces is used to develop the milling force model of a helical ball end mill.
