In fact, flexible manufacturing models are prevalent, exemplified by the common customization we encounter in our daily lives. This consumer-oriented, demand-driven production approach contrasts sharply with traditional mass production methods. In flexible manufacturing, the critical factor is the responsiveness of the production line and supply chain. The flexibility of FPC manufacturing can be articulated in two key dimensions.
As mass production approaches its limits, consumer demand for individualized products continues to grow. Flexible manufacturing arises in response to this trend, characterized by small batch sizes and a diverse range of offerings. With effective planning, it achieves efficient control over the production process. In fact, flexible manufacturing models are widely adopted, such as the everyday customization we experience. This approach prioritizes consumer needs and demand, standing in stark contrast to conventional mass production. In flexible manufacturing, the primary challenge is the agility of the production line and supply chain. The flexibility inherent in FPC manufacturing can be understood in two distinct aspects.
The first aspect pertains to the production capacity’s ability to respond flexibly, specifically the machinery and equipment’s capability to handle small batch production.
Its equipment utilization rate and productivity are exceptionally high, and the unit cost is relatively low. However, it can only process one or a few similar parts, making it challenging to handle the production of multiple varieties in small to medium batches. As the era of mass production transitions to one that adapts to market fluctuations, the ability to quickly develop multi-variety, high-quality, and low-cost products becomes a key competitive advantage for manufacturing systems. Flexible manufacturing is well-suited to meet this need and is increasingly vital in the evolution of manufacturing.
The second aspect pertains to the agile and precise response capabilities of the supply chain.
In flexible manufacturing, the supply chain system is designed to respond to individual production and distribution demands. This marks a shift from the traditional “production-supply-sales-people-financial-materials” model of “production-based sales” to a “sales-based production” approach. Here, production instructions are entirely driven by consumer demand, resulting in a value chain that operates as a directed activity with a clear focus on “people-financial-products-materials-sales.” This transformation presents significant challenges for production machinery and fundamentally changes the traditional supply chain.
The “flexibility” of the manufacturing system can be demonstrated through the following dimensions:
1. **Equipment flexibility**—the machine’s capability to process various parts as product types change.
2. **Process flexibility**—the ability to use different materials to manufacture a specific part or product type.
3. **Product flexibility**—the unique conditions that allow for changes in the economics and speed of producing a new set of parts or products.
4. **Work and rest flexibility**—the ability to manage failures and continue producing a specific set of parts or product types using alternative methods.
5. **Production capacity flexibility**—the ability to maintain profitability across various production volumes.
6. **Expansion flexibility**—the potential for modular, gradual expansion.
7. **Production flexibility**—the range of part or product types that the system can produce.
**Current Flexible Manufacturing Technologies:**
1. **Flexible Manufacturing System (FMS):** Multiple fully automated CNC machine tools linked by a centralized control and material handling system, enabling the processing and management of diverse varieties and small to medium batches without machine downtime.
2. **Flexible Manufacturing Cell (FMC):** Introduced about 6 to 8 years after FMS, FMC consists of 1 to 2 machining centers, industrial robots, CNC machine tools, and material transport and storage equipment, offering flexibility for processing a variety of products.
3. **Flexible Manufacturing Line (FML):** This production line serves as a bridge between single or small-variety high-volume non-flexible automatic lines and small to medium-volume multi-variety FMS. The processing equipment may include general machining centers and CNC machine tools, as well as specialized machines. The material handling system is less flexible than that of FMS but offers higher productivity, represented by discrete production’s flexible manufacturing system and the distributed control system (DCS) in continuous production. Its hallmark is the flexibility and automation of the production line.
4. **Flexible Manufacturing Plant (FMF):** FMF integrates multiple FMSs with an automated three-dimensional warehouse and a computer system, providing a comprehensive FMS that covers ordering, design, processing, assembly, inspection, and delivery. It includes CAD/CAM and implements a computer-integrated manufacturing system (CIMS), realizing flexibility and automation across the entire production process, including management, product processing, and material storage and transport. FMF represents the pinnacle of automated production, reflecting the most advanced automated application technologies globally. It connects manufacturing automation, product development, and operational management into a cohesive whole, exemplified by the Intelligent Manufacturing System (IMS) that controls material and information flow, characterized by achieving factory flexibility and automation.
