Abstract

The instantaneous cutting energy consumption of the cutter teeth is an important indicator for evaluating the dynamic cutting performance of efficient milling cutters. The existed milling cutter cutting energy consumption solution model lacks of the distribution information of the instantaneous cutting energy consumption on the cutting edge of the cutter teeth, and cannot accurately identify the complexity and variability of the instantaneous cutting state at different positions of the cutting edge. Aiming at the problem that the distribution area of the instantaneous cutting energy consumption of the cutting edge cannot be accurately identified due to the uncertainty of the cutting boundary, a solution method for the instantaneous boundary of the main and secondary cutting edges is proposed to obtain the equations of the main and secondary cutting edges under vibration and wear. A solution model for the instantaneous cutting energy consumption distribution and its fractal dimension is established to obtain the distribution of the instantaneous cutting energy consumption on the cutter teeth. A method for identifying the dynamic distribution characteristics of cutting energy consumption is proposed. The extreme value, coefficient of variation and first-order difference of the fractal dimension are used to reveal the dynamic characteristics of the instantaneous cutting energy consumption distribution of different cutter teeth, and the experimental results of milling surface morphology and tooth flank wear depth are used to verify the proposed method.
