数控加工工艺与编程毕业设计

1、高效率、高精度加工是数控机床加工最主要特点之一。利用数控机床加工，其产品加工的质量一致性好，加工精度和效率均比普通机床高出很多，尤其在轮廓不规则、复杂的曲线或曲面、多工艺复合化加工和高精度要求的产品加工时，其优点是传统机床所无法比拟的。本课题对异性体、复杂的曲线、多工艺复合化加工进行探索，设计出三种切实可行的工艺流程及工艺装备。在产品的加工过程中，工件在夹具内的定位和夹紧显得特别重要。须根据六点定位对产品进行合理的定位，欠定位、完全定位还是过定位都须根据实际的生产过程决定。夹具是涵盖了从加工到组装的几乎所有操作过程的一种装夹设备。由于大量的加工操作需要装夹，夹具设计在制造系统中就变得非常重要，它直接影响加工质量，生产率和制造成本。本文通过分析支承套的结构特点和加工要求，制定了一套较合理的夹具设计，从而为保证该零件的加工精度将提供一种经济实用的工艺装备，具有一定的实用价值。通过对各种定位夹紧装置的分析比较，选择并组合了一套既能够满足加工要求的，又比较简洁的装置，并对各工步进行数控编程。

2、The high efficiency, the precision work are one of numerical control engine bed processing most XXin characteristics. Using the numerical control engine bed processing, its product processing quality uniformity is good, the processing precision and the efficiency outdo compared to the ordinary engine bed very much, especially when outline not rule, complex curve or curved suXXXce, multi-craft recombine processing and high accuracy request product processing, its merit is the traditional engine bed is unable to compare. This topic to the opposite XXX body, the complex curve, the multi-craft recombine processing carries on the eXXloration, designs three practical and feasible technical processes and the craft equipment. In the product processing process, the work piece appears in jig localization and the clXXp specially importantly. Must act according to six localizations to carry on the reasonable localization to the product, owes the localization, locates completely crosses the localization all to have to act according to the actual production process decision. The jig covered from has processed clXXps the equipment to the assembly nearly all operating process one kind of attire. Because the XXssive processing operation needs to install clXXps, the jig design changes can it be that the constant weight in the XXnufacture system to want, it affects the processing quality directly, the productivity and the production cost. This article through the XXXXysis support components, the air compressor snifting valve lid as well as the supporting the unique feature and the processing request which wraps, has formulated a set of reasonable jig design, thus for guaranteed this components the processing precision will provide one economical practical craft equipment, will have certain practical value. Through to each kind of localization clXXp XXXXysis comparison, chose and combines a set both to be able to satisfy the processing request, and the quite succinct installment, and carried on the numerical control progrXXming to each step working procedure.
