摘 要

科學(xué)技術(shù)和社會(huì)的蓬勃發(fā)展，對(duì)機(jī)械加工產(chǎn)品的質(zhì)量，品種和生產(chǎn)率提出了越來越高的要求。數(shù)控加工技術(shù)就是實(shí)現(xiàn)產(chǎn)品加工過程自動(dòng)化的現(xiàn)代化的措施之一，應(yīng)用數(shù)控加工技術(shù)能提高加工質(zhì)量和 生產(chǎn)率，解決若干普通機(jī)械加工所解決不了的的加工技術(shù)問題，大大降低加工成本，提高綜合經(jīng)濟(jì)效益，還能極大改善工人的勞動(dòng)條件，提高工人的素質(zhì)。
機(jī)床數(shù)控是以數(shù)字的形式實(shí)現(xiàn)自動(dòng)加工控制的一門技術(shù)，其指令的數(shù)字和文字編碼的方式，記錄在控制介質(zhì)上，經(jīng)過計(jì)算機(jī)和處理后，對(duì)機(jī)床各種動(dòng)作的順序位移量及速度實(shí)現(xiàn)自動(dòng)控制。

機(jī)械加工工藝是實(shí)現(xiàn)產(chǎn)品設(shè)計(jì)，保證產(chǎn)品質(zhì)量，節(jié)約能源，降低消耗的重要手段，是企業(yè)進(jìn)行生產(chǎn)準(zhǔn)備，計(jì)劃調(diào)度，加工操作，安全生產(chǎn)，技術(shù)檢測(cè)和健全勞動(dòng)組織的重要依據(jù)，也是企業(yè)上品種、上質(zhì)量、上水平，加速產(chǎn)品更新，提高經(jīng)濟(jì)效益的技術(shù)保證。
　　工藝規(guī)程的編制是直接指導(dǎo)產(chǎn)品或零件制造的工藝過程和操作方法的工藝文件，他直接對(duì)企業(yè)的產(chǎn)品質(zhì)量、效益、競(jìng)爭能力起著重要的作用。
　　機(jī)械工業(yè)是國民經(jīng)濟(jì)各部門的裝備部，國民經(jīng)濟(jì)各部門的生產(chǎn)技術(shù)水平和經(jīng)濟(jì)效益，在很大程度上取決與機(jī)械工業(yè)所能提供裝備的技術(shù)性能、質(zhì)量和可靠性，因此，機(jī)械工業(yè)的技術(shù)水平和規(guī)模是衡量一個(gè)國家科技水平和經(jīng)濟(jì)實(shí)力的重要標(biāo)志。
　　近年來，世界各國都把提高產(chǎn)業(yè)競(jìng)爭力和發(fā)展技術(shù)、搶占未來經(jīng)濟(jì)制高點(diǎn)作為科技發(fā)展提出更高的要求，特別是制造技術(shù)更加得到了重視。所以，我們要振興機(jī)械工業(yè)，使之成為國民經(jīng)濟(jì)的支柱產(chǎn)業(yè)。從而確定機(jī)械工業(yè)在國民經(jīng)濟(jì)中的重要地位，同時(shí)也向機(jī)械工業(yè)提出更高的要求。

Science, technology and society, the vigorous development of mechanical processing product quality, variety and productivity put forward more and more high demand. Nc machining technology is to realize the modernization process automation products processing, one of the measures applied nc machining technology can improve the processing quality and productivity, solve several ordinary mechanical processing not settled by the processing technical problems, and greatly reduce processing cost, improve the overall economic benefit, but also can greatly improve labor conditions, enhances the quality of workers.
The machine tool CNC based on digital form a realization of automatic processing control technologies, the door of digital and text coded instructions, recorded in control the way through computer medium, and dealing with various action of machine, after the order of displacement and speed the realization of automatic control.

The machining process is to realize the product design, assure product quality, to save energy and reduce consumption is the important means of enterprise production preparation, plan scheduling, processing operations, the safety in production, technology detection and improve labor organization, also be the important basis on the variety, quality of enterprise, on level, accelerate update products, improving economic efficiency technology guarantee.
Procedure preparation is direct guidance products or parts manufacturing process and operating method of the process documents, he directly to enterprise's product quality, efficiency, competition ability play an important role.
Machinery industry is the armaments department sectors of the national economy, national economic sectors of manufacturing technology level and economic benefits, to a great extent, depends on machinery industry can provide equipment technical performance, quality and reliability, therefore, machinery industry technology level and scale is the measure of a country's scientific and technological level and economic strength important symbol.
In recent years, all countries in the world to promote industrial competitiveness and development technology, preempted future economic commanding heights as technology development put forward higher request, especially the manufacturing technology more get the attention. So, we must promote machinery industry, has become a pillar industry of the national economy. Thus determine machinery industry in the national economy, but also the important position to put forward higher requirement of mechanical industry.
