The process flow of Sheet Metal Processing refers to the entire process of gradually changing the shape, size, material properties, or assembly and welding of parts in a predetermined order during the production process, until a sheet metal part that meets the shape and size requirements is manufactured. For more complex structural parts, their production and processing generally require many processes such as material preparation, unfolding and layout, cutting blanks, forming, and assembly to be completed. Additionally, cold sheet metal processing is often combined with welding, metal cutting, heat treatment, and inspection processes to form a complete product manufacturing process.

Process specifications for sheet metal processing

The process flow specifies the machining process of the parts, while the specific machining content is guided and controlled by the process specification.

Process specification is a technically feasible and economically reasonable process plan selected by process technicians based on the requirements of product drawings, the characteristics of the workpiece, production batch, and the existing equipment and production capacity of the enterprise. After careful comprehensive analysis and comparison of several possible process plans, it is a technical document that guides the production process of parts. In the technical document, the blank used for the part, its processing method, and specific processing dimensions are specified; The nature, quantity, sequence, and quality requirements of each process; Equipment models and specifications used in each process; The form of processing tools (such as auxiliary tools, cutting tools, molds, etc.) used in each process; Quality requirements, inspection methods, and requirements for each process.

Generally speaking, when it comes to the processing technology of all sheet metal parts, it is often not completed by a single cutting and stamping workshop. Many parts may also be interspersed with mechanical processing, heat treatment, surface treatment, etc. Cross workshop and cross department operation guidance is controlled by their corresponding process specifications. However, in different industries, especially when processing sheet metal components with low professional technical requirements and low complexity, a comprehensive process specification is often compiled to guide production.
