复合镗铣加工中心双刀库可视化设计界面

Abstract

复合式镗铣加工中心是一种功能较为齐全的数控加工机床，其加工效率为普通机床的5~10倍，现在已经普遍应用于各机械加工行业，但是传统的数控加工中心只有一个刀库，换刀时间较长。本文复合式镗铣加工中心采用的是双刀库的自动换刀设计思想，即固定换刀刀库和随机换刀刀库主要是为方便镗床和铣床在机加工过程换刀效率从而提高机床的加工精度并且提高机床的加工效率从而提高整个加工中心的工作效率。一般加工中心的刀库都是封闭的，但是在加床加工的过程中尤其是随机换刀刀库看不刀机床中主轴和刀库中各个刀座上具体是存放的哪种刀具，本文针对此问题使用vb6.0编程语言研究设计了复合镗铣加工中心双刀库可视化的人机界面，实现机床随机换刀刀库的可视化控制，实时监控机床随机换刀的运行状态，通过实验运行证明，该运行系统具有有效稳定性，精确性，实时性。 Composite boring milling machining center which has complete function is the NC machine. The processing efficiency is 5 to 10 times than the ordinary machine tool. So far, it has been widely used in the machining industry, but the traditional CNC machining center with only a Knife Bank spends longer time of changing knife. In this paper, automatic changing tool thought of double tool bank was applied in composite boring milling machining center. Namely, fixed knife bank and random changing knife bank were used to improve the efficiency of changing knife in the machining process. At the same time, machining efficiency and machining precision were improved. Generally, the knife bank of machining center was sealed. But for the random knife bank, the knife type on the knife seat which was installed on the spindle and knife bank couldn’t be identified in the machining process. According to above problems, by means of VB6.0 programming language, the visual human computer-interface of double knife bank was designed in the machining center. And the visual control of random changing knife bank was accomplished. At the same time, running state of random changing knife was controlled in the real time. The experiment showed that the system was stable, accurate and real-time.
