前言

在大学的最后一段时间，我有幸参加了数控实训。

通过这次学习实践，使我对数控的掌握从当初的朦胧不懂到如今的熟悉并会操作机床，加工零件这次数控中级培训对我来说，这是一次提高、一次借鉴、一次实践，使我在大学的学习中深感收获巨大，这将受益终生。

近年来，随着计算机技术的发展，数字控制技术已经广泛应用于工业控制的各个领域，尤其是机械制造业中，由于数控化加工可以让机械加工行业朝高质量，高精度，高成品率，高效率方向发展,最重要的一点是还可以利用现有的普通车床，对其进行数控化改造，这样可以降低成本，提高效益。

普通机床经经历了近两百年的历史。

随着电子技术、计算机技术及自动化，精密机械与测量等技术的发展与综合应用，生产了机电一体化的新型机床一一数控机床。

数控机床一经使用就显示出了它独特的优越性和强大生命力，使原来不能解决的许多问题，找到了科学解决的途径。

数控车床是数字程序控制车床的简称，它集通用性好的万能型车床、加工精度高的精密型车床和加工效率高的专用型车床的特点于一身，是国内使用量最大，覆盖面最广的一种数控机床，也是是一种通过数字信息，控制机床按给定的运动轨迹，进行自动加工的机电一体化的加工装备，经过半个世纪的发展，数控机床已是现代制造业的重要标志之一，在我国制造业中，数控机床的应用也越来越广泛，是一个企业综合实力的体现。

这次数控实训，内容有车床，铣床。

这次学习偏向于机床操作。

通过电脑编程模拟和下车床操作，以及加工零件。

我对数控的学习有了一定的掌握。

对于刚开始的编程理解，我个人还是比较感兴趣，从当初的一知半解到现在熟悉运用每个命令，并理解其含义，都是自己每天不断的摸索和老师耐心的教导息息相关。

一、 对数控编程和模拟的理解和运用

我很荣幸能有这么好的老师来教我们数控编程，其实学习最主要的还是靠自己去多练，但关键的时候有老师指导，这样还是进步快点。

特别是刚开始接触编程和机械加工的时候，有老师指导进步特别快。

记得老师开始讲编程的过程，特别对经常使用的代码给介绍出来，然后对点位的理解和计算。

对模拟好的零件进行模拟加工。

通过这些知识点的学习，我才渐渐的理解数控编程的一些基本要领。

机床上对刀是我之前遇到的最大难题，这是由于命令使用不习惯，和基本感念理解不够透彻，不过通过后面的反复练习，现在已经熟悉掌握了模拟系统。

如今已经能够看懂图，知道走刀路线。

以及涉及到的点位能够进行换算。

二、理论知识的学习和理解

对于老师的加工要求，我已经认真的去学习，当然，相对要记住每个知识点，还是有一定的差距，但我有信心能把理论知识学习好。

我认为最主要的是去理解每个知识点，而不是死记硬背，因为许多的理论知识都会在实际操作中用到，而且必须掌握。

只有完全的理解理论上的知识，才能更好的去完成实际的操作。

比如机床上的按钮，走刀路线，刀补等。

都涉及到许多理论知识。

只有把理论知识吃透了，才能在加工过程中认真的去遵守规则，更安全的完成零件的加工。

首先熟练运用模拟仿真软件进行模拟仿真，在经过仔细的工艺过程构思后，编制好程序，进入仿真；首先对刀，做到准确快速无误。

然后输入导入程序进行模拟加工。

加工成功无语后，携带程序到实际机床实践加工，注意易错事项后，顺利加工。
