Sensitivity analysis of geometric error for a novel slide grinder based on improved Sobol method and its application

In order to improve both the accuracy and efficiency of grinding slide, this paper designs a novel grinder with dual-lead-dual-head. Since geometric error is one major contributors causing machine inaccuracies, sensitivity analysis performed identify critical terms, an application self-test also given. The volumetric model 38 errors built using homogeneous transformation matrix (HTM) multi-body system (MBS) theory. An improved Sobol method quasi-Monte-Carlo algorithm utilized perform global (GSA) in entire workspace. particular further carried out on basis machining characteristics typical slide. All results are validated through compensation simulations. Besides that, some discussions given determine total considering workspace requirements. Finally, pitch yaw between dual-grinding-head investigated, based results, quick approach proposed reduce measurement load practice.
