The flexible manufacturing cell consists of one or several CNC machine tools or machining centers.
The unit can automatically change tools and fixtures as needed to machine different workpieces.
The flexible manufacturing unit is suitable for processing parts with complex shapes, simple processing steps, long processing time and small batch size.
It has greater equipment flexibility but low flexibility for personnel and processing.
The so-called flexibility refers to the ability of a manufacturing system to adapt to changes in various production conditions.
It is related to system solutions, people and equipment.
The flexibility of the system solution refers to the degree of freedom in processing different parts.
Personnel flexibility refers to the ability of the operator to ensure the processing tasks, the amount of time and time required to adapt.
Equipment flexibility means that the machine can adapt to the processing capabilities of new parts in a short period of time.
In the face of the individualized demand for products, and rising manufacturing costs, improving the flexibility of production has always been the demand of manufacturers.
Flexible Manufacturing Units (FMC) and Flexible Manufacturing Systems (FMS) have emerged.
FMC is actually an extension of the CNC machining center.
It is generally composed of a machining center and an industrial robot, and is controlled by a background computer for programmable control.
The FMS evolved from DNC is generally composed of several machining centers, industrial robots and automatic guided vehicles (AGVs), which are controlled by the back-end computer.
FMC/FMS has certain flexibility, but due to limited equipment hardware functions and huge equipment investment, it often fails to produce the expected benefits in the face of changing market demands.
Therefore, a detailed input-output assessment is required when selecting this technology.
