Abstract

A method for machine tool design parameters optimization is presented to obtain the desirable cutting depth in the milling process, with the constraints of cutting stability and its uncertainty, which is rarely considered in the traditional design. According to the chatter frequency distribution and the modal test experiment, the key component of the machine tool which determines the minimal cutting depth is located. Targeting at the thickness of external contour and the internal rib of the component, the sensitive design parameters to be modified is selected according to sensitivity analysis. The difference between the desirable cutting depth and actual cutting depth is converted to structural dynamic flexibility modification. With the minimum local structural modification, The desirable cutting depth is obtained to meet the material removal rate (MRR) under the constraint of static stiffness and weight. The method is verified in the optimization design of a CNC machining center.
