Since 2000, many of automotive parts enterprise in China began to use PDM and ERP to manage substance and infor- mation. ERP used parts of the function, just include material flow management, informat
本文对铝合金缸体的缸盖安装面粗糙度公差在刀具应用方面进行了分析.同时研究了铣刀几何角度中副偏角对表面粗糙度的影响,通过对试验数据的分析和优化,确定了如何在生产实践过程中合理使用副偏角,才能满足缸体表面粗糙度要求.
铝合金材料在汽车行业的应用日益广泛,在汽车整车轻量化、小型化等方面起到很大作用.PCD(聚晶金刚石)刀具具有高硬度、较低的热膨胀系数以及与有色金属亲和力小等特点,是铝合金加工刀具材质的首选.本文介绍了PCD类刀具的概念和功能,提出了PCD类刀具在加工铝合金缸体时的加工应用技巧,阐述了PCD类铣削刀具刃口的局部钝化处理对刀具磨损以及改变切削基理的方法和建议,为提高加工寿命及提升加工性能提供了一些可行
In recent years, machine vision systems have been widely used in the mass production of automotive manufacturing processes, as an "eye" of equipment, based on the need for automation, flexibility and
沥青混合料离析是造成沥青路面局部损坏的根本原因之一，针对沥青混合料出现的级配离析现象，以颗粒离散元法为基础，通过编制PFC 数值模拟程序模拟出几种不同级配的离析后的沥青混合料，并评价级配离析对混合料性能的影响。结果 表明，在不同离析程度下，粗集料离析对沥青混合料性能的影响大于细集料离析的影响。
