The present application is described in terms of improvements made on the basis of numerical control systems, but it should be noted that the present application can be applied to not only three-axis linkage numerical control systems.
Specifically, the power supply mode of the numerical control machine tool is introduced: firstly, the numerical control machine is connected with an external power supply (or called as a main power supply), and in the actual use process, the main power supply is converted into an unused power supply to respectively supply power to different devices of the numerical control machine, such as: a power supply for the operation of the numerical control system, a power supply for the operation of the power supply main shaft and the like. Wherein, the power supply for the operation of the numerical control system is generally more than or equal to 24V.
As shown in fig. 2, the numerical control system is divided into three modules, including: a connection module 201, an information saving module 202 and a power failure recovery operation module 203. When the numerical control machine is powered off, the connection module 201 is triggered, the connection module 201 controls an Uninterruptible Power Supply (UPS for short) to charge the numerical control system, generates an information storage signal, and sends the information storage signal to the information storage module 202. And the information storage module 202 receives the information storage signal sent by the connection module 201, stores the memory information of the machine tool during the latest power failure according to the information storage signal, and sends the stored memory information to the power failure recovery operation module 203. The power failure recovery operation module 203 receives the memory information sent by the information storage module 202, and controls the machine tool to recover operation according to the memory information after the machine tool recovers power on.
