简介:摘要:零件图形,是用来表达零件的形状;尺寸标注是反应零件的真实大小及相对位置。在机械加工过程中,零件图尺寸标注是一项重要要素,尺寸标注方式的不同,会直接影响零件制造过程的加工、测量等方式方法。
简介:摘要:飞机起落架的结构主要是由高强度合金钢材料构成,是飞机重要的承受载荷部件。起落架的使用环境是比较复杂的,处于高温,高震动区域的零件较多。高温,高振动会使起落架零件比较容易产生磨损,腐蚀,热损伤等缺陷,而这些缺陷如果放任不管会进一步产生裂纹并会造成起落架零件断裂,对飞机的安全造成严重后果。所以,目前的民用客机的起落架都会根据设计要求设置使用寿命和检修周期,通常来说是10年为一个检修周期。在检修过程中维修人员需要将起落架完全分解并进行目视检查,NDT检查等一系列的检查来判断起落架零件是否有缺陷。这其中热损伤就是一种常见又十分难以发现的缺陷类型。而本篇文章主要介绍热损伤的产生原因以及热损伤对零件的影响。
简介:摘要:薄壁零件广泛地应用在机械加工制造业中,它具有重量轻、结构紧凑、节省材料等优点,同时又有刚性差、强度弱的特点,在加工中容易变形,加大形位误差,直接影响零件的加工质量。本文就以薄壁零件的数控铣削加工工艺及自动编程加工进行分析,确保薄壁零件的加工质量。
