A commonly used probe system for on?machine measurement in domestic was modeled based on the theory of finite ele?ments analysis. Then by altering some measure parameters such as the length of probe stylus and probing angle, triggering force was simulated and the influences of vary measure parameters on measurement error and measurement uncertainties were studied. A new method to evaluate measurement uncertainty based on the simulation results of finite elements analysis was put forward.
