Adj ustment Method for Machining Errors of Machine Tool Based on Poor Information Fusion Technology
摘要
Abstract
Based on fusing membership function method,maximum membership degree method, rolling mean method,arithmetic mean value method and bootstrap method,a poor information fusion technology was proposed to realize adj ustment for machining errors of machine tool.The output small sample data in machine tool trial processing were fused using the poor information fusion technology to obtain estimated true value of the parts,and the machining errors of machine tool could be adj usted to make the machined parts meet quality requirements.Then the output small sample reliable data was obtained in machine tool adj usted well processing,and the estimated interval of the reliable data could be predicted using the fuzzy set theory under the given confidence levels.The results of simula-tion and experiments show that the poor information fusion technology can realize the error adj ust-ment of machine tool,and the adj usted machine tool is reliable,and the feasibility of utilizing the in-formation fusion technology to adj ust machine tool was verified.关键词
