Abstract

The invention relates to a milling cutter designing method and a milling cutter, in particular relates to a method for designing a low-entropy and safe high-speed milling cutter and the high-speed milling cutter, and aims to solve the problems that the entropy cannot be controlled due to disordering of particle swarms of the milling cutter and the safety of the high-speed milling cutter is reduced. According to the characteristic that the disordering of the particle swarms of a high-speed milling cutter assembly is associated with the reducing of the safety, a safety reducing process is described by virtue of an entropy determination method; by virtue of an entropy model, a mesoscopic motion state is judged, and the safety reducing process is determined; by virtue of an entropy control method, a control variable for controlling the safety reducing process is revealed, and the disordering of the particle swarms can be effectively controlled; macroscopic and mesoscopic structure parameters are collaboratively designed by virtue of a low-entropy high-speed milling cutter safety designing method; the safety and stability of the low-entropy milling cutter are verified. The diameter of the milling cutter is 63mm, the number of tool teeth is 4, the tool teeth are unequally distributed, included angles between the teeth are 88 degrees, 89 degrees, 90 degrees and 93 degrees, the tooth root of a tool body is of a chamfer and transition circular arc structure, and a front blade installation angle is 2 degrees. The method is applied to milling cuter designing and high-speed milling.

Description

technical field

[0001] The invention relates to a low-entropy safety design method for high-speed milling cutters, in particular to using the particle swarm entropy method of high-speed milling cutter assemblies to identify the safety decline characteristics of high-speed milling cutter assemblies; using the entropy of particle swarm movement of high-speed milling cutter assemblies The value change rate can be used to judge the degree of safety decline of high-speed milling cutters; the safety design method of minimum entropy value of high-speed milling cutters is proposed to control the safety decline of high-speed milling cutter components, and a low-entropy safety high-speed milling cutter is developed. Background technique

[0002] The high-speed milling cutter accumulates high energy due to high-speed rotation and is subjected to high-energy impact during the cutting process, which will lead to deformation of the high-speed milling cutter component and damage such as duc...

Embodiment Construction

[0075] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0076] The specific steps of a design method of a low-entropy safe high-speed milling cutter of the present embodiment are as follows:

[0077] Step 1. Entropy model of safety decline of high-speed milling cutter

[0078] During the service of high-speed milling cutters, the particle swarm of the milling cutter assembly is in a gapless vibration state. Under the impact load of intermittent cutting, the particles deviate from the original stable position and move irregularly, resulting in the occurrence of disordered movement of the particle swarm; The higher the degree of group disorder, the more fragile the bonding force between the particle groups of the milling cutter component, and the more prone to dislocation slip, dislocation climb, dislocation accumulation, grain boundary migration, microcrack propagation, crystal plane cleavage, etc. ...
