Abstract

The invention discloses a compensation method for the multi-tooth uneven cutting behavior of a high-speed milling cutter and relates to the compensation method for the cutting behavior of the high-speed milling cutter. The invention aims at solving the problem that the quality of the processing surface is reduced due to the uneven cutting of the existing high-speed multi-tooth milling cutter. The compensation method comprises the following steps of firstly, establishing a cutting behavior model of the high-speed milling cutter under the vibration of the milling cutter and the influence of cutter tooth errors; secondly, recognizing the cutting behavior of the high-speed milling cutter, adjusting the tooth pitch and the rotating speed, and performing primary compensation; thirdly, recognizing the high-speed milling cutter for the second time, and performing secondary compensation on the multi-tooth uneven cutting behavior; fourthly, verifying the compensation effect. According to the compensation method disclosed by the invention, the problem that the quality of the processing surface is reduced due to the multi-tooth uneven cutting of the high-speed milling cutter under the vibration of the milling cutter and the influence of the cutter tooth errors is solved.

Description

technical field

[0001] The invention relates to a compensation method for cutting behavior of a high-speed milling cutter, in particular to a compensation method for multi-tooth uneven cutting behavior of a high-speed milling cutter, and belongs to the technical field of high-speed milling cutter design. Background technique

[0002] When milling with high-speed milling cutters, on the one hand, it is required to reduce the machine time with a great metal removal rate, and on the other hand, it is required to have low cutting vibration and high surface quality. For this reason, milling cutters generally adopt tooth distribution with unequal pitch, and improve the surface quality of high-speed milling by dispersing the energy of cutting vibration. The above method can effectively suppress the vibration of the cutting force, but the unequal pitch distribution of the cutter teeth will also cause uneven cutting of the milling cutter, destroying the uniformity of the high-speed m...
