Embodiment 1

[0062] Take the actual production of an elevator parts manufacturer in Nantong, Jiangsu as an example. Process a batch of magnet mounting plates. The material of the parts is 40Cr. The surface is semi-finish milled. The surface length of the parts is 24cm and the width is 20cm. The required accuracy range is [-0.5, +0.5] and the surface roughness is 1.0.

[0063] Step 1: First, the user enters in the part information input module that the processing feature of the part is milling plane, the material of the part is 40Cr, and the processing property is semi-finishing.

[0064] Step 2: The system will output that the tool type of the tool to be selected is end mill, and the tool material is PBCN. The triggering rules are as follows:

[0065] IF part processing feature = milling plane and processing property = semi-finishing THEN tool type = end mill

[0066] IF part material = 40Cr and processing properties = semi-finishing THEN tool material = PBCN

[0067] The third step: the...

Abstract

The invention relates to an intelligent selection method and system for numerical control machining tools. The system is composed of a part machining information input module, a tool type and material selection rule base management module, a cutting case base management module and a cutting case retrieval configuration module. Relevant information of machined parts is input to the system, the system can automatically output the tools used for machining similar parts in a case base, a technologist can directly use the tools and machine the parts only by transferring or properly correcting the geometric parameters of the tools, operation is convenient and quick, and the requirements for professionalization of operators are greatly lowered.

Description

technical field [0001] The invention and the tool selection system particularly relate to an intelligent selection method and system for CNC machining tools based on rule-based reasoning (RBR) and case-based reasoning (CBR). Background technique [0002] Cutting tools are an important part of the manufacturing system. Reasonable cutting tool selection has a great influence on the geometry, dimensional accuracy, surface quality and processing cost of parts. In recent years, with the development of the machinery industry, customers have higher and higher requirements for products, accompanied by continuous improvement of parts processing requirements, and more and more types of parts. In order to meet the processing requirements of parts, there are more and more types of cutting tools used in production. This leads to more and more complex tool preparation before production, and higher and higher professional requirements for craftsmen. Therefore, based on the above problems...
