Multi-channel numerical control system and multi-channel control method thereof

Abstract

The invention discloses a multi-channel numerical control system and a multi-channel control method thereof. The method comprises the following steps that: step one, a plurality of PLC logic control modules are stored in a numerical control system and a data mapping zone is arranged respectively for each PLC logic control module; step 2, a display system is used to obtain a channel configuration parameter including the activation channel number and a management system invokes the PLC logic control modules with the number corresponding to the activation channel number so as to activate a plurality of channels; and step 3, the management system sends control data of each channel to the data mapping zone of the channel in real time, so that the multi-channel PLC system carries out execution. According to the invention, multi-channel logic processing mutual interference can be avoided and the design difficulty of the PLC logic control module can be simplified. Moreover, invoking and synchronization between channels can be realized and the processing process can be ensured to be carried out successfully.

Description

technical field [0001] The invention relates to the field of numerical control systems, in particular to a multi-channel numerical control system and a multi-channel control method thereof. Background technique [0002] Today, the use of compound machine tools for processing reduces the auxiliary time for loading and unloading workpieces, changing and adjusting tools, and errors in the intermediate process, improves the machining accuracy of parts, shortens the product manufacturing cycle, and improves production efficiency and manufacturers' market response Compared with the traditional production method with decentralized process, it has obvious advantages. With the wide application of composite processing technology, composite machine tools have been promoted. [0003] In order to adapt to the practical application of compound CNC machine tools, a CNC system supporting multiple channels has emerged. The CNC system can control different processing in different channels, ...

AI Technical Summary

Problems solved by technology

[0004] At present, the multi-channel control ability of CNC systems in the domestic market is weak, mainly because of multi-channel configuration, multi-channel PLC and machine tool operation panel control, etc., which cannot meet the needs of users.
