Cutting forces have significant influence on the accuracy of workpiece dimensions due to tool and work-piece deflection during high speed milling. Based on the cutting force model presented,cutting forces were fore-casted and simulated with the help of MATLAB. Simulation results indicate that the distribution of cutting forces dur-ing milling process greatly affects dimensional accuracy of finished parts. Then force distribution was simulated and analyzed further by changing cutting parameters to find the most reasonable values. Finally,a high speed milling force simulation system was established on the basis of database functions to offer a better choice for selection and optimization of NC machining process parameters.
