机械类英文翻译 请各位大侠手动翻译 好的补分

零件和毛坯的三维造型利用Pro/E软件实现，该部分介绍了该软件三维造型的思路和难点。模具部分介绍了利用Pro/E设计模具结构的具体过程，工程图的绘制首先利用Pro/E软件生成二维图，利用CAXA电子图版绘制完成。随后根据零件的工艺性和精度要求拟定了工艺路线，接着计算了每道工序的切削用量，确定了定位夹紧方案。最终，完成了零件的机械加工工艺规程卡。
接下设计了三套专用夹具，两套是铣床专用夹具，一套是钻床专用夹具。专用夹具的设计参考了夹具设计手册和夹具图册，首先利用Pro/E进行三维造型，然后生成二维图，利用CAXA电子图版绘制工程图。最后，运用MasterCAM软件进行数控加工的仿真，并用CIMCO Edit完成走刀轨迹仿真。
设计难点：在零件的三维造型时，由于前端，是圆形，底部是椭圆，所以中间的过渡部分用Pro/E的常规过渡方法无法画出。需要用边界混合绘制出曲面，然后在实体化。在设计铣床夹具时，由于装夹工件非常困难，一个人不能完成。最后，采用把夹具拆分，然后放倒装夹工件的方法解决了这个问题。

Answer 1

Parts and the use of rough three-dimensional modeling Pro / E Software, which provides information on the three-dimensional modeling software and difficult ideas. Section describes the use of molds Pro / E design of die structure of the specific process, project mapping the first to use Pro / E software to generate two-dimensional maps, the use of electronic chart drawn CAXA completed. Subsequent parts of the process in accordance with accuracy requirements and the development of a process line, and then calculated each of the cutting process used to determine the positioning clamp program. Ultimately, the completed parts of the machining process of order card.

To take over the design of the three sets of special fixture, the two sets is dedicated milling fixture, a fixture is a special drill. Dedicated fixture design fixture design reference manuals and fixture book, first of all, the use of Pro / E three-dimensional modeling, and then to generate two-dimensional maps, the use of electronic chart CAXA drawn engineering drawings. Finally, the use of MasterCAM software for NC machining simulation, complete with CIMCO Edit trajectory simulation tool.

Design difficult: in parts of three-dimensional modeling, because the front is round, the bottom is an oval, so the middle part of the transition to use Pro / E transition of the conventional methods can not be painted. Need to draw the boundary surface mixed, and then of the entity. Fixture in the design of milling, the workpiece is very difficult due to clamping, a person can not be completed. Finally, the use of the split clamp and then clamping down the workpiece to solve the problem.
