在三维造型时，零件表面的多个曲面相交部位不易于过渡，多次改变倒圆角的顺序的来完成过渡。用上下模的方式开模时，生成的模具体积块有飞边和棱角，且零件侧面上的两处铸字位置有干涉，通过创建多个模具体积块采用多向开模的方式解决这些难题。机械加工工艺规程设计中工序安排以工序集中为原则，定位使用一面两销的方式，首道工序中用来定位的通孔为铸孔，因此形状不规整，不能使用圆柱销定位，采用圆锥销能够达到定位要求。在机床专用夹具设计时，用于加工斜孔的专用钻套在夹具体上不易于定位和安装，采用钻套与零件内孔配合的方式方便定位和安装。

Answer 1

蜗牛译文：In the three-dimensional modeling, a plurality of curved surface intersection is not easy transition, change the fillet repeated sequence to complete the transition. Using the upper and lower die die die way, volume generated by the flash and the edges and corners, and parts on the side of the two type of position of interference, by creating multiple mold volume block multi-directional opening the way to solve these problems. The machining process planning design procedure to process on principle, using a two positioning pin way, first step hole designed Weizhu hole positioning, so the shape of irregular, cannot use the positioning pin, taper pin can be achieved by positioning requirements. In the machine tool fixture design, used for processing inclined hole drill sleeve on the clamp body is not easy to locate and install, the drill sleeve and part hole manner with the convenient location and installation

Answer 2

IIn three-dimensional modelling, because of not being easy to transit for intersection of multi-curved surfaces on the surface of the part, transition is achieved by changing the sequence of smoothing many times. when going on die-sinking with upper and lower dies, the mould volume block generated has flying edge and corner, Two positions of typecasting on the part side are interfered, through building multi mould-volume-block, these problems are solved by utilizing multi-directional die-sinking. In the design of the machining process technic regulations, procedure concentration is used as fundamental for procedure arrangement, the way of one-surface and two-pin is used for fixing position, the through-hole used to fix position is blowhole in first procedure, its shape is irregular, fixing position of cylindrical pin is not used, the conical pin can meet the positioning requirements. in the design of special fixture of machine tool, it is not easy to be positioned and fixed for special drill bushing used to machine inclined hole in the fixture body, it is convenient to be positioned and fixed for utilizing the coordination between the drill-bushing and part-bore .
