数控车床的加工编程技术摘 要在数字化制造技术中，计算机数控技术和数控编程技术是最重要的之一本文主要对行CNC加工，采用系统对进行数控编程加工。首先是对工件进行加工工序的确定，并且进行工艺分析，装夹方式的选择，切削用量的确定。再对了选择。然后就工艺路线进行编程加工。当前数控加工的重点发展方向是无图化生产、单件高精度并行加工、少人化无人化加工，这就要求数控机床能满足高速、高动态精度、高刚性、热稳定性、高可靠性、网络化以及与之配套的控制系统，最重要的是模具三维型面加工特别注重机床的动态性能国内已有一些公司引进了高速铣床，并开始应用。国内机床厂陆续开发出一些准高速的铣床，并正开发高速加工机床。数控技术是指用数字、文字和符号组成的数字指令来实现一台或多台机械设备动作控制的技术。它所控制的通常是位置、角度、速度等机械量和与机械能量流向有关的开关量。数控的产生依赖于数据载体和二进制形式数据运算的出现。数控技术是与机床控制密切结合发展起来的。1952年，第一台数控机床问世，成为世界机械工业史上一件划时代的事件，推动了自动化的发展。 数控机床是一种技术密集度及自动化程度很高的机电一体化加工设备,是综合应用计算机、自动控制、自动检测及精密加工精度高,质量容易保证,发展前景十分广阔,因此掌握数控车床的加工编程技术尤为重要。The abstract in the digitization technique of manufacture, the computer numerical control technology and the numerical control programming technology is a most important this article mainly aims at in 2010 the Shandong Province numerical control big game numerical control vehicle components 1 line of CNC processing, uses the Fanuc system to carry on the numerical control programming processing to the components.First is carries on the processing working procedure to the work piece the determination, and carries on the craft analysis, the attire clamps the way the choice, the cutting specifications determination.Again to cutting tool choice.Then carries on the programming processing on the craft route. The current numerical control processing prioritize direction is does not have chart production, single unit high accuracy parallel processing, few person nobody melts the processing, this request numerical control engine bed can satisfy high speed, the high dynamic precision, the high rigidity, the thermostability, the redundant reliability, the network as well as with it necessary control system, most importantly the mold three dimensional profile processing paid great attention to the engine bed the dynamic performance domestic to have some companies specially to introduce the high speed milling machine, and started to apply.The domestic machine tool factory one after another develops some high speed milling machi
