The prototyping process for large quantities of precision prototype parts is a systematic project that covers from initial design to final delivery. It follows a “plan – execute – monitor – optimize” cycle to ensure the smooth progress of mass production. The following is the core workflow:

Uma pergunta comum aqui é: Why is pre – production preparation more important for large – quantity precision prototyping than small – batch? The answer is that in small – Produção em lote, problems can be corrected in time with less loss. No entanto, in large – quantity production, a small mistake in the pre – preparation stage, such as improper material selection or unreasonable process planning, may lead to the scrapping of thousands of parts, resulting in huge economic losses.

2. Key Links in Pre – production Preparation: Lay the Foundation for Mass Production

Pre – production preparation is the key to ensuring the success of large – quantity precision prototyping. It involves multiple aspects, and every detail needs to be carefully considered.

2.1 Design Optimization for Manufacturability

The design of precision prototype parts directly affects the efficiency and cost of mass production. Therefore, design optimization should focus on Design para fabricação (Dfm). The specific optimization points are as follows:

• Simplify the structure: Avoid overly complex shapes that are difficult to machine in batches, such as deep holes with small diameters or irregular curved surfaces that require special tools. Por exemplo, if a part has multiple similar grooves, it can be designed as a uniform structure to facilitate the use of combined tools for batch machining.
• Standardize parts: Use standard components as much as possible, such as standard screws and nuts. This not only reduces the cost of custom – made parts but also shortens the supply cycle.
• Consider tolerance matching: In the design, clearly specify the tolerância range of each part, and ensure that the tolerances between matching parts are compatible. Por exemplo, the tolerance of the shaft and the hole in a rotating pair should be designed according to the requirements of assembly accuracy to avoid excessive fit gaps or difficult assembly.

Por exemplo, parts used in high – temperature environments should choose heat – resistant materials such as Inconel; parts that require high wear resistance should choose materials such as hardened steel.
• MACHINABILIDADE: Materials with good machinability can improve the efficiency of batch machining and reduce tool wear. Por exemplo, aluminum alloy is easier to machine than titanium alloy, which is more suitable for large – quantity production of parts with general precision requirements.
• Custo – effectiveness: Under the premise of meeting performance requirements, choose materials with moderate prices. Por exemplo, for non – carregar – bearing structural parts, engineering plastics can be used instead of metals to reduce costs.

2.3 Scientific Process Planning and Scheduling

Process planning e scheduling are important guarantees for improving production efficiency and ensuring on – entrega de tempo.

• Process planning: Determine the most suitable usinagem e fabricação processes for each part. Por exemplo, for parts with high precision requirements on the outer circle, the process of turning – moagem – polishing can be adopted; for parts that need assembly, the assembly sequence should be determined in advance to avoid rework.
• Scheduling: Make a detailed production schedule based on the production capacity of the equipment, the supply cycle of materials, and the delivery date. Use production management software to arrange the production tasks of each machine and each operator reasonably, ensuring that the throughput of the production line is maximized. Por exemplo, arrange the machining tasks of similar parts on the same machine to reduce the time for tool change and adjustment.
