我也出现了这个问题,楼主解决了吗?是什么原因?
The deviations from the evaluation are useful in correcting the part NC program to control the machine tool. The geometric analysis of the machine tool is performed using components and assemblies that provide displacements in the three motion directions. For displace- ments, besides the deviations ...
geometric fractional Brownian motionIn this paper, we investigate asymptotic behaviour for rates of discrete time hedging errors in models with respect to geometric fractional Brownian motion with Hurst parameter . We analyse the rates of hedging errors due to discrete time trading when the true ...

Sensitivity analysisS-shaped specimenIDENTIFICATIONOPTIMIZATIONACCURACYThe geometric error of a machine tool is the main factor influencing its accuracy. Studying the sensitivity of various geometric errors of machine tools can provide a certain theoretical basis for analyzing their accuracy. In this study,...

Error analysisFreeform surfaceThis paper presents a novel measurement error model for closed-loop surface metrology. In these surface metrology systems, the motion of the probe tip is strictly constrained on a parallel surface that is separated from the measured sample surface of constant displacement...
