types of manufacturing systems

The three main types of manufacturing system are small batch, large batch and continuous manufacturing.
With the rise of automation and computer-aided manufacturing, agile manufacturing and mass customization manufacturing systems are also being used in an attempt to combine the low cost of mass manufacturing with the ability of small batch manufacturing to respond to customer needs.
The small batch manufacturing system includes work workshop, machine workshop and prototype workshop.
Manufacturers have many different tools to complete any combination of the steps required to create a single or several product.
Small batch manufacturing processes tend to bounce parts between workstations.
Low-volume manufacturing systems with higher productivity
The unit cost is higher compared to the high volume system, but it provides flexibility and is able to produce small and medium batches that large volume manufacturers may reject.
The latest innovation in small batch manufacturing is 3-
D printer, able to create 3D models and parts from computer models.
Each model may be a unique prototype or an item that requires hundreds of hours of hand-made work.
A classic example of a mass manufacturing system is the assembly line.
Each tool or machine is placed in a position where it can quickly process the part and forward it to the next machine or worker.
The focus of the mass manufacturing system is on speed in order to produce as much as possible.
Mass manufacturing systems often follow a line or flow directly between machines.
This minimizes the travel time between stations and reduces the risk of damage during processing.
For a particular product, the mass manufacturing system is often optimized.
Switching between products has higher tooling costs and downtime compared to small-batch manufacturing systems.
When producing large quantities (usually thousands or more), high volume processing provides a lower unit cost.
Continuous Manufacturing systems or continuous flow systems do not produce discrete batches like small and high-volume manufacturing systems.
The continuous manufacturing system creates the continuous flow of products.
The refinery is a typical example of a continuous manufacturing system.
You can produce a small portion of a gallon of oil or kerosene, but a widget is either complete or partially completed.
Continuous Manufacturing includes chemical production, metal refining and plastic extrusion.
The continuous flow manufacturing system will continue to operate as long as raw materials, pumps or motors are supplied.
Continuous flow manufacturing costs low per unit, such as per pound or per gallon.
Agile manufacturing is an attempt to combine the flexibility of small batch manufacturing with the lower unit cost of mass manufacturing.
Lines of the same machine are aligned instead of a long line.
The blank or raw material starts at one end and is wound between workstations until the finished product falls off from the other end.
In another model, a computerized CNC or CNC machine performs multiple manufacturing operations on one blank.
Multiple cutting, drilling and welding operations are completed by a machine workstation.
The part will then be removed and sent for further processing or inspection.
Agile manufacturing allows a new proportion of turnaround speed between products
Processing the entire production line, but usually requires a larger capital investment in CNC machines or multiple sets of tools.
Mass customization is a combination of small batches and mass manufacturing to create personalized customized products.
In some cases, a large number of produced parts are assembled into unique components required by the user.
The modern fast food restaurant is a model of mass customization service.
Rolls and bread are produced in bulk and shipped to the restaurant.
The vegetables are delivered to the restaurant for use.
Meat is cooked according to enterprise standards.
Each hamburger or meal is then assembled into an order.
Custom phones and PCs assembled into custom order units are examples of this.
In other cases, the qualityproduced semi-
Customize the finished components to create a personalized unit. Mass-
Another example is a hand drawn baby doll with the required skin, hair and eye color.
A small investment in human customization or adding accessories from warehouses creates a custom product that costs slightly more than mass customization
The goods produced still depend on a large number
Manufacturing of most components.
