随着现代机械加工的快速发展，机械加工技术快速发展，慢慢的涌现出了许多先进的机械加工技术方法，比如微型机械加工技术、快速成形技术、精密超精密加工技术等。 With the rapid development of modern mechanical processing, mechanical processing technology rapid development, gradually emerged a lot of advanced machining technology and methods, such as micro mechanical processing technology, rapid prototyping technology, precision ultra-precision machining technology, etc. 微型机械加工技术 Micromachining technology 机械加工 Mechanical processing 随着微/纳米科学与技术（Micro/NanoScienceandTechnology）的发展，以本身形状尺寸微小或操作尺度极小为特征的微机械已成为人们认识和改造微观世界的一种高新科技。微机械由于具有能够在狭小空间内进行作业，而又不扰乱工作环境和对象的特点，在航空航天、精密仪器、生物医疗等领域有着广阔的应用潜力，并成为纳米技术研究的重要手段，因而受到高度重视并被列为21世纪关键技术之首。[1] As Micro/nano science and technology (Micro/NanoScienceandTechnology) development, the shape of itself little tiny size or scale operation in Micro machinery has become a recognized and reforming the microscopic world of a kind of new and high technology. Because of micro machine and can carry on the work in a small space, without disrupting the working environment and the characteristics of the object, in areas such as aerospace, precision instrument, biological treatment, has broad application prospects, and become the important means of nanotechnology research, thus attaches great importance to and is listed as one of the key technology of the 21st century. [1] 快速成形机械加工技术 Rapid prototyping machining technology 快速成形技术是20世纪发展起来的，可根据CAD模型快速制造出样件或者零件。它是一种材料累加加工制造方法，即通过材料的有序累加而完成三维成形的。快速成形技术集成了CNC技术、材料技术、激光技术以及CAD技术等现代的科技成果，是现代先进机械加工技术的重要组成部分。 Rapid prototyping is developed in the 20th century and can be quickly manufactured according to CAD model. It is a kind of material accumulative processing manufacturing method, namely through the orderly accumulation of the material and complete the three-dimensional forming. Rapid prototyping technology integrates modern technological achievements such as CNC technology, material technology, laser technology and CAD technology. It is an important part of modern advanced machining technology. 精密超精密机械加工技术 Precision superprecision machining technology 精密和超精密加工时现代机械加工制造技术的一个重要组成部分，是衡量一个国家高科技制造业水平高低的重要指标之一。20世纪60年代以来，随着计算机及信息技术的发展，对制造技术提出了更高的要求，不仅要求获得极高的尺寸、形位精度，而且要求获得极高的表面质量。正是在这样的市场需求下，超精密加工技术得到了迅速的发展，各种工艺、新方法不断涌现，同时也促进了各种相关产品技术性能的提高。 An important component of modern machining manufacturing techniques in precision and ultra-precision machining is one of the important indicators of the high and low levels of high-tech manufacturing in a country. Since the 1960 s, with the development of computer and information technology, puts forward higher requirements on manufacturing technology, not only demand the high precision of size, shape, and required to obtain high surface quality. It is in this market demand, the ultra precision machining technology obtained the rapid development of technology, new methods constantly emerging, but also improve the technical performance of a variety of related products.
