Abstract

A high-feed milling cutter tooth flank friction and wear boundary detection and calculation method belongs to the field of milling cutter tooth flank wear calculation methods, and the invention can completely describe the change characteristics of the cutter tooth flank friction and wear boundary , to reveal the formation process of the friction and wear boundary on the flank of the cutter tooth. In the present invention, a plurality of high-feed milling cutters with the same structure are used to carry out milling experiments with different cutting strokes respectively; a method for detecting the friction and wear boundary of the cutter tooth flank is proposed, and the change of the cumulative friction and wear boundary of the cutter tooth flank is revealed Characteristics; construct the instantaneous contact relationship model between the cutter tooth flank and the machined surface under the action of cutter tooth error and milling vibration, propose the instantaneous friction and wear boundary criterion of the cutter tooth flank, and obtain the instantaneous friction and wear boundary of the cutter tooth flank; The similarity of the coefficients of the experimental and simulation curve equations of the tooth friction and wear boundary verifies the correctness of the above model and method. The invention is mainly used for the detection and calculation of the friction and wear boundary of the cutter tooth flank of the milling cutter.

Description

technical field [0001] The invention belongs to the field of calculation methods for flank wear of high-feed milling cutters, and in particular relates to a method for detecting and calculating the friction and wear boundary of flanks of high-feed milling cutters. Background technique [0002] The change characteristics of the wear boundary of the flank of the milling cutter is an important parameter to evaluate the service life of the milling cutter. The measurement and calculation results of the friction and wear boundary directly affect the evaluation of the remaining service life of the milling cutter and the design of the milling process plan. High-feed milling cutter is a typical high-efficiency milling tool. During the intermittent cutting process, affected by factors such as cutter tooth error and milling vibration, the contact relationship between the cutter tooth flank and the workpiece processing surface changes frequently, resulting in The formation process of th...
