A Study on Flexible Measuring System Based on CMM

Abstract

随着市场竞争的日益激烈,对产品提出了T、Q、C、S的要求,即时间更短、质量更好、成本更低、服务更优。综合产品设计、制造、检测等各个环节的质量自动控制系统成为发展的必然。其中,快速、精确的三维测量是制造过程中的重要环节,贯穿整个设计、开发、加工、检测与质量保证的过程。三坐标测量机(CMM)是制造业中的标准三维精密测量设备,广泛使用于航空航天、汽车、造船、装备制造及模具制造等领域。但目前在对工件表面进行测量与评价时,主要是靠人工编程操作获取被测工件表面的三维特征,这不仅需要大量的人工工作量,而且使得测量结果依赖于检测人员的经验和对工件检测原则的理解,其测量效率低,不能适应制造业快速发展的要求。本课...With the increasingly fierce competition of market, products are demanded with T, Q, C, S, which means shorter time, better quality, less cost and better service. Rapid acquisition of high-precision coordinate data from parts having complex geometry is one of the most important techniques in modern manufacturing process. Among many coordinate acquisition methods, Coordinate measuring machine are w...学位:工程硕士院系专业:物理与机电工程学院机电工程系_仪器仪表工程学号:X200518201
