Processing progress instruction control system and method for multichannel numerical control system

Abstract

The invention relates to a processing progress instruction control system and method for a multichannel numerical control system. The system comprises an explainer, a standard processing module, a workpiece program operation sequence, a workpiece program command sequence, a task controller module, and a motion controller module. The method comprises the steps: employing the explainer, the standard processing module, the workpiece program operation sequence, the workpiece program command sequence, the task controller module and the motion controller module in the system for cooperation, achieving the channel-cross program instruction analysis and operation of a multi-channel numerical control system, the waiting and synchronization of different channels and a function of work sequence control through the reading-writing operation of the public IO state data between the channels. The system is large in processing range, is high in processing efficiency, is high in processing precision, and is low in cost.

Description

technical field [0001] The invention relates to the field of numerical control systems, in particular to a multi-channel numerical control system machining progress instruction control system and method. Background technique [0002] In recent years, the domestic numerical control industry has developed well. Users have higher and higher requirements for product complexity, processing efficiency and automation, and stricter control over investment costs. Some multi-channel machine tools such as double-turret lathes , multi-station milling machines and turn-milling compound machine tools have gradually become the first choice for CNC machine tool users. With the improvement of the performance of the hardware equipment of the CNC system, and the application requirements of compound processing and flexible production, the multi-channel CNC system has gradually become the development direction of the CNC system. Multi-channel control technology has gradually become an important...

Problems solved by technology

The existing multi-channel CNC system adopts the method of copying and mirroring the single-channel CNC system architecture and allowing each channel to execute concurrently. It can complete the processing tasks of multiple workpieces of different processes on the same CNC machine tool, but the tasks are different It is related, and some processing tasks require multiple processes of the same part to be processed on the same CNC machine tool. During processing, the channels have time or process correlations. If the existing multi-channel CNC The system framework requires continuous labor to control the time and progress of the process, which not only requires additional cost investment, but also reduces the efficiency of processing
