The flexible manufacturing cell consists of one or several CNC machines or machining centers.
The unit can automatically change tools and fixtures as needed to machine different workpieces.
Definition
The flexible manufacturing unit is suitable for processing parts with complex shapes, requiring simple processing steps, long processing time, and small batch size.
It has greater equipment flexibility but lower flexibility for personnel and processing.
The term flexibility refers to the ability of a manufacturing system to adapt to changes in various production conditions. It is related to system solutions, personnel, and equipment.
System solution flexibility refers to the degree of freedom in processing different parts.
Personnel flexibility refers to the operator’s ability to adapt to processing tasks, required time, and quantity.
Equipment flexibility means that the machine can adapt to the processing capabilities of new parts in a short period of time.
Working principle
In the face of individualized demand for products and rising manufacturing costs, improving the flexibility of production has always been the demand of manufacturers. Flexible Manufacturing Cells (FMCs) and Flexible Manufacturing Systems (FMSs) have emerged.
FMCs are actually an extension of the CNC machining center. They are generally composed of a machining center and an industrial robot and are controlled by a background computer for programmable control.
The FMSs evolved from CNCs and are generally composed of several machining centers, industrial robots, and automatic guided vehicles (AGVs), which are controlled by the back-end computer.
Related question
FMC/FMS offer certain levels of flexibility, but due to limited hardware capabilities and high equipment costs, they may not always deliver the expected benefits in response to changing market demands. Hence, it is recommended to conduct a detailed input-output assessment before implementing this technology.
