Embodiment

[0039] A method for screening the cutting performance of composite ceramic cutters with different components, comprising the following steps:

[0040] 1) In the material library of Deform-3D software, according to the existing tool material behavior model, input the relevant parameters of ceramic tool materials, and establish ceramic tool material models of different components in the material library of Deform-3D software;

[0041] Since the material library of Deform-3D software does not contain the B required for turning simulation 4 C-TiB 2 Ceramic tool material, therefore applied to B 4 C-TiB 2 Data for ceramic tool materials must be established based on existing tool materials. In the material library of Deform-3D software, Al 2 o 3 Ceramic material is regarded as a rigid tool material whose behavior model is defined by Power's law and described by Eq. (1).

Abstract

The invention relates to a method for screening cutting performance of composite ceramic cutters with different components. The method comprises the following steps of: firstly, inputting various related parameters of ceramic cutter materials in a finite element software Deform-3D material library according to an existing cutter material behavior model, and establishing the ceramic cutter materials with different components; establishing a three-dimensional entity model of a ceramic cutter by using three-dimensional cartographic software, importing the three-dimensional entity model into Deform-3D software, and setting simulation related parameters; and through a single-factor experimental design method, obtaining main cutting force and tool temperature data of ceramic tools with different components in the simulation process by analysis, comparing the cutting performance, and screening out corresponding ceramic tool components. The invention provides a simple, reliable and accurate research method for screening out ceramic cutter material components with optimal cutting performance from composite ceramic cutters with different components, and plays roles in shortening the design period, avoiding a large number of cutting experiments, reducing the design cost and the like in the research and development process of the ceramic cutters.

Description

technical field [0001] The invention relates to a simulation cutting processing method, in particular to a method for screening the cutting performance of composite ceramic cutters with different components by using simulation technology, and belongs to the technical field of ceramic cutter simulation. Background technique [0002] The development of the manufacturing industry constantly puts forward new requirements for products. Due to the long cycle and high cost of experiments, experiments alone cannot follow up the production needs. The emergence of simulation technology has solved this problem. With the development of science and technology, the accuracy of cutting simulation software has been gradually improved, and the data that cannot be measured by cutting experiments, such as cutting temperature and cutting stress, can be observed within the allowable error range, and the shape of chips and tools at each step can be observed. and workpiece status, more convenient ...
