  1、数控机床控制技术

  1.1.数控机床控制技术的概念

  数据机床的控制一般是指通过数控程序命令的输入, 对数控机床的控制核心下达其指定工作的指令, 通过数据传输,使得数控机床遵循预定的工作程序命令, 实现对所需要加工的机械零件进行自动化操作的过程。在操作之前, 首先需要确定零件在数控机床上的安装位置以及刀具与机械零件之间的距离和相关尺寸参数等信息以及机床刀具所要操作的路线等具体参数等。知道了这些参数以后,程序员对加工参数进行程序编制,通过输入窗口将工作指令输入至电脑的控制系统,然后控制系统依据所制定的程序执行命令, 进行规范的自动操作,从而加工机械零件。

  第一部分: 位置环来测量加工元件的精度,判断其是否与系统的脉冲信号能够准确匹配,主要是来测量加工元件每次位置变化的距离,判断外部的倍频电路与系统的分辨率脉冲是否相符。只有当测量加工元件与分辨率脉冲的比值达到100倍以上, 才符合要求。比如, 在进行位置测量过程中,元件脉冲次数为10次/ mm,那么只有系统的分辨率达到0.001mm才能算是符合匹配要求。

  第二部分:对位置环KV值进行设定以及调节。KV值通常的设定是用来当作数控机床数据进行的, 在数控控制系统中, 对KV值的数值的单位和地址都需要进行正确指定。KV值是判断机床性能状态以及操作精度准确与否的重要参数他值显示了数控机床运动的坐标,并能够展示运动过程的性能好坏程度。

  2.2 换件法

  在维修过程中,难免会发现零部件损坏现象,因此必须更换,这一般是应用于电气控制部分的维修,包括电路板更换维修和电气关键更换维修。更换电路板属于模块化维修,需要有备用电路板,这样能够方便快捷的消除故障,但是维修费用比较高。更换电气元件维修,主要是通过排查,找出故障部件,对其单个或多个部件进行维修,这种维修方式需要工作人员的技术水平比较高,需要能够快捷的找到故障部件,并进行更换,但是这种方法的优点是成本费用相对比较低。
