Craft is an important means of making furniture. Process design is the basis for structural design. The production method and process depend on the process design and it plays an important role in the production of the organization. The process design mainly includes the analysis of the structure of the furniture type and the determination of the technical conditions, the preparation of the process card and the process flow chart.
Type structure analysis and determination of technical conditions First analyze the material composition of furniture products; secondly, analyze which type of production means should be used for the product. Single-piece production uses a process consisting of general-purpose equipment; a large number of production uses a one-way assembly line consisting of special machine tools, automatic machine tools, and combined machine tools with large production capacity; mass production (replacement at specified period and production in batch form) Between the above two categories, as far as possible, the assembly line of special machine tools and automatic machine tools is used. Finally, according to the structural assembly drawing, the parts and parts list is compiled, including the model, use, peripheral size and part size of the furniture product, allowable tolerances, materials used, hardware accessories, finishing and rubber types, assembly quality, technical conditions, Product packaging requirements, etc.
Preparation of process cards and process flow diagrams
The craft card is the guiding document in production and the basis for production preparation, production organization and economic accounting of various departments. It mainly includes the part name, quantity, material, size, process, tool, process specification, number of operations in each process, working time quota, etc. The process flow is a document of the order of parts processing, which clearly indicates the entire manufacturing process of the part. However, it is necessary to pay attention to the preparation process, so that each processing equipment should achieve the highest possible load rate, and the number of equipment should be minimized and the process route should not be repeated.
