In the machining industry, how to achieve traceability in the processing link?
For the CNC machining industry, the assembly, warehousing and delivery from raw materials -> blanks -> surface treatment -> machining -> semi-finished products -> finished products require several processes of production and inspection to complete. How to truly realize the traceability of these links is a difficult problem in industry management. CNC machining manufacturers will propose a traceability plan for the machining industry based on years of project implementation and research in the CNC machining industry. Raw Material Warehousing and IQC Traceability: All purchased components and raw materials require delivery appointments in the Supplier Delivery Management System. After the audit is passed, the warehouse uses PDA to count the quantity and category according to the delivery list (for materials without company material labels, only materials with supplier labels), print material labels and paste them on the materials, and place the information in the temporary storage area for incoming materials. In the return area, the system automatically generates an IQC inspection request and an inspection task list. The IQC inspection is qualified, and the warehouse staff uses the PDA to carry out the storage and shelf operations according to the storage order, including error-proofing settings, information binding and returning to the ERP system, and the traceability of the storage information is completed. Part processing production traceability: The machining workshop collects raw materials according to the production work order. Through the traceability function of parts processing, the PDA barcode scanner performs scanning operations (or operates on an industrial tablet, and scans the work order information with a scanner gun), and the parts processing traceability system automatically collects and collects information such as materials, batches, and quantities. Traceability of parts processing process: machined parts have a traceability mark (traceability card or QR code), which is the ID card of the part, and the mark is generated through the unified coding rules for part processing traceability , the content of the mark should include product model, production date, production batch number, processing personnel, processing equipment material specifications, materials, material suppliers, etc. Traceability of parts quality control in machining process: Each workpiece in CNC machining process passes through the parts machining barcode scanning report through each process, and the automation equipment can be automatically collected after being connected through the programmable controller. After the key process is processed, it is necessary to check the quality of the workpiece through the parts processing PQC inspection, and the unqualified data control is not allowed to flow to the next process; the processing process, equipment, batch, date, personnel, qualified and defective data are collected. FQC control and traceability of machined parts: FQC collects inspection data in the part processing traceability system software, and the traceability system automatically determines the inspection results according to the inspection plan. After passing the inspection, it can print a qualified barcode identification card and go through the warehousing procedures . CNC machined parts complete the warehousing control traceability: after the warehouse consignee receives the parts, it is put into the warehouse with a PDA barcode scanner through the traceability system, and the traceability system will check and control whether the parts are qualified? Is it more than the order received? Waiting for information to prevent errors. Automatically collect information such as order number, date, part code, name, batch, quantity, etc. Using the MES system to achieve product traceability can play a preventive and early warning role in the production process of the product, effectively ensure the quality of the product, and quickly and effectively complete the tracking and recovery of the product production and inspection process.
