面向梁类零件的可制造性几何特征识别方法
Manufacturability geometric feature recognition method for beam parts
摘要
Abstract
In order to further improve the production efficiency and reduce the cost,the manufacturabili-ty geometric feature recognition method of beam parts was studied to overcome the difficulty in obtain-ing machining features and improve the degree of automation in the manufacturability examination pro-cess of beam parts.Firstly,the manufacturing geometric features of beam parts were classified,and the recognition methods of Boolean intersection operation and surface attribute calculation were studied to identify the manufacturing geometric features.Secondly,the recognition process for groove features of beam parts was introduced,and a core surface association algorithm based on Boolean intersection op-eration was proposed to achieve precise recognition of groove.The offset gap method was proposed to accurately calculate the maximum depth and the depth to diameter ratio of grooves.Finally,a prototype system for automatic recognition of beam parts'manufacturability geometric features was established in CATIA,and a manufacturability geometric feature checking module was developed.The feasibility and efficiency of the proposed methods was verified by an example test.关键词
