Milling Material Removal Rate Based on Machining Stability Theory

To ensure the cutting efficiency in milling,three-dimensional stability limit diagram of the spindle speed,axial depth of cut and radial depth of cut was established. Aiming at maximizing the material removal rate,optimized cutting parameters were chosen to guarantee the high-quality and high efficiency milling based on the three-dimensional stability limit diagram. Simulation results show that for different dynamic characteristics of the milling system,the change trends of the maximum material removal rate are different along with the radial depth of cut increasing. Therefore,it is necessary to find the optimal radial cutting depth based on the three-dimensional stability limit diagram for obtaining the maximum material removal rate.
