The research of the method of predicting cutting forces has the very important meaning for determining manufacturing process ，reducing 案 machining deformation and improving the machining quality. Now it will make use of the DEFORM-3D milling module to E simulate the process of the three-dimensional milling in the way of rotating feed. A comparison is made between simulated A results with measured results to find that the error is within 20% ，namely，the simulated results agree well with the measured C data ，basically satisfying the requirements for predicting cutting forces.
