Automatic acquisition method of batch workpiece NC machining progress based on multi-information fusion

Abstract

The invention provides a multi-information fusion based automatic collection method for batched numerical control workpiece machining progress. A machine tool numerical control system is connected with a computer terminal through a network cable, and machining start-stop information is read and processed through an interface program; in addition, a power sensor is introduced in between a machine tool motor and a frequency converter, the power sensor is connected with the computer terminal through an analog / digital conversion module to acquire real-time power information during machining; the power sensor acquires machining quality information during machining by communicating with a quality inspection system; progress data in the process of machining are acquired according to the machining start-stop information, the real-time power information and the machining quality information and by means of comprehensively processing the information. The method has the advantages of timely feedback, statistical accuracy, rich statistical content and the like, support is provided for improvement of management and control ability of enterprises on production fields and optimized operation of machining workshops, convenience is brought to customers to monitor executive conditions of orders anytime, and service capability for customers is improved.

Description

technical field [0001] The invention relates to the fields of machinery manufacturing, network and communication technology, and information processing technology, and belongs to information collection and signal processing methods in a manufacturing execution system, in particular to a method for automatically collecting batch workpiece numerical control processing progress based on multi-information fusion. Background technique [0002] The actual processing progress information of the workpiece in the processing workshop feeds back the completion status of the current processing task. The processing progress status of the workpiece reflects the task allocation and processing status of each machine tool in the workshop, and reflects the processing performance and efficiency of the existing equipment of the manufacturing enterprise. The processing accuracy of parts and the completion status of ordered products are the basis for mechanical manufacturing process planners and p...

Problems solved by technology

[0004] In view of the fact that the processing progress information of workpieces in the workshop is mainly based on manual statistics, although the processing progress information can be obtained by inserting macro instructions into barcodes, RFID, PLC, and NC codes, due to the existence of trial cutting, rework, scrapping, etc. Complicated situations often lead to redundant statistics of processing quantities, resulting in inaccurate acquisition of production progress information and other issues. The purpose of the present invention is to provide a multi-information fusion-based system with timely data feedback, accurate statistics, rich statistical content and reduced labor costs. The method of automatic acquisition of NC machining progress of batch workpieces
