英文摘要	A method for machine tool design parameters optimization was presented to obtain a desirable cutting depth in the milling process, under the constraints of cutting stability and its uncertainty, which have been rarely considered in the traditional design. According to the chatter frequency distribution and the modal tests results, the key influential component of the machine tool which determines the minimal cutting depth was located. Targeting at the thickness of external contour and internal rib of the component, the sensitive design parameters to be modified were selected according to a sensitivity analysis. The difference between the desirable cutting depth and actual cutting depth was converted to an amount for structural dynamic flexibility modification. With the minimum local structural modification, the desirable cutting depth was obtained to meet the requirement of material removal rate (MRR) under the constraint of keeping unchanged the static stiffness and the static weight. The method was verified via the optimization design of a CNC machining center. © 2016, Editorial Office of Journal of Vibration and Shock. All right reserved.
