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 discloses a simulation model and verification method for a milling cutter cutting machining error forming process and belongs to the technical field of a milling cutter. In order to disclose a milling machining error forming process, the invention provides a method for describing a cutter tooth machining transition surface dynamic forming process. A milling machining error forming process calculation model is established; dynamic characteristics and control variables of the machining error forming process are illuminated; through combination of a simulation example and an experiment result, effectiveness of the model is verified; and the end milling cutter cutting machining error forming process is described accurately. According to the method, machining error formation undermilling vibration, milling cutter track and pose, and cutter tooth track and pose continuous change condition can be reflected. According to the verification method for the end milling cutter millingmachining error calculation model, an end milling cutter dynamic cutting movement model and a cutter tooth cut-in / cut-out calculation model in the method are verified, and the effectiveness and feasibility of the models are determined.

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 ...
