坐标测量机（CMM）已被广泛用于提高产品质量、生产率和可靠性。这款功能强大的仪器通过为用户提供高度准确和可靠的测量结果来帮助用户。许多研究涉及各种不同的方法的应用已经进行，以提高CMM的性能。探讨了有限元分析在三坐标测量机测头系统研究中的应用。有限元建模被用来调查的探头触针，预行程的变化（波瓣效应）和相关的测量不确定性的位移。文中还讨论了探针的不同特性对探针工作的影响
Coordinate measuring machines (CMMs) have been widely used for enhancing product quality, productivity and reliability. This powerful instrument assists the user by providing them with highly accurate and reliable measurement results. Many studies involving the application of various different methods have been carried out to enhance the performance of CMM. This paper discusses the application of finite element analysis (FEA) to study the probe system of CMM. Finite element modeling is utilized to investigate the displacement of the probe stylus, pre-travel variation (lobing effects) and the associated measurement uncertainty. Different characteristics of styli have been considered and the corresponding effects on the probe operation are reported
