基于提高大型精密零件刮削精度的有限元法应用

刮削能够获得较高的尺寸、形状和位置精度,广泛应用于机床导轨面、滑行面以及量具等的精密加工。而工件支承位置和方式的选择合理与否,在很大程度上影响刮削的周期、质量和精度,大型工件尤其突出。利用ANSYS软件,模拟不同的支承方式,通过优化分析零件的变形,做出正确判断,以期达到最佳的刮削状态。

Application of Finite Element Method based on improving the large parts scraping accuracy

Scraping could obtain high size, shape and position accuracy, it is widely used on precision machining of the machine guide surface, slide surface and measuring tools. So making a reasonable selection of parts support position and style or not could affect the scraping cycle, quality and accuracy on some degree, especially the large parts. Using ANSYS software can simulate different mode of supporting, through optimizing and analyzing the deformation, then making a correct decision, reaching the best scrapi...
