Method for modeling milling force in peripheral milling process

Abstract

The invention discloses a method for modeling a milling force in a peripheral milling process, which aims to solve the technical problem of the poor prediction precision of a milling force model established in the milling process in the conventional methods. In the method, the milling force model simultaneously comprising side-blade cutting and bottom-blade cutting is established so as to overcome the shortcoming that only the side-blade cutting is taken into account in the peripheral milling force modeling process in the conventional methods. Compared with the prior art, the method has the advantages of simplifying an equality relation A between a measured force and a predicted force as cutter eccentricity parameters are first determined, and allowing that the cutter is axially cut-in and divided into a plurality of sections in a calibration test to make a cutting-in depth equal to any value meeting conditions so as to make the calibration test more consistent with an actual machining state; and due to the adoption of a direct calibration method, all parameters in the model can be calibrated by one calibration test to save test cost.
