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。
