通过研究自动换刀的原理。在开放式数控系统上,采用全软件方法实现自动换刀。减少了硬件的投入,降低了成本。同时与系统有更好的兼容,从而提高了系统的可靠性。
Nowadays, PLC has been used in the existing Automatic Tool Changer (ATC) of CNC system on the whole. In this paper, the principle of ATC was studied, based on which the ATC using software method was implemented in the open-CNC system. Some experimental results show that the proposed method can reduce the costs on the hardware equipment as well as promise better compatibility to the system which can improve the reliability of the system remarkably.
