Problems solved by technology

However, the milling process is unstable, so the formation process of machining errors is also unstable.
The current research on machining error is based on constant cutting parameters and stable cutting process, which cannot reflect the change of vibration during milling and the influence of cutter tooth wear on the formation process of machining error.

Abstract

The invention relates to a simulation model and a verification method of a milling cutter cutting machining error forming process, belonging to the technical field of milling cutters. In order to reveal the formation process of milling machining errors, the present invention proposes a method for describing the dynamic formation process of the transition surface of cutter tooth machining, establishes the solution model of the milling machining error formation process, and clarifies the dynamic characteristics and control variables of the machining error formation process. Simulation examples and experimental results verify the validity of the model and accurately describe the formation process of end mill cutting machining errors. The invention can reflect the formation of machining errors under the condition of continuous changes of milling vibration, milling cutter trajectory and posture, cutter tooth trajectory and posture. According to the verification method of the end mill milling error solution model in the present invention, the dynamic cutting motion model of the end mill and the cutter tooth cutting in and out solution model constructed in the present invention are verified to determine the validity and feasibility of the model.

Description

technical field [0001] The invention relates to a model simulation method reflecting the error formation process, in particular to a simulation model and a verification method of the milling cutter cutting machining error formation process, and belongs to the technical field of milling cutters. Background technique [0002] The end mill is a typical tool for processing large structural parts, and the machining error is an important index for evaluating the processing quality of large structural parts. When the end mill is milling large structural parts, the cutting error is not strictly periodic due to the influence of milling vibration, milling cutter tooth error and cutter tooth cutting edge wear. Therefore, in order to improve the processing surface performance and ensure the reliable processing technology Therefore, it is necessary to reveal and control the formation process of structural milling errors. [0003] The cutting process of the end mill directly affects the ...
