The factors affecting selection of manufacturing process are mentioned below.
- Volume of production
- Type of component
- Expected quality standards
- Properties of component
- Technical viability of the process
- Rate of production
- Limitations of shape and size
- Surface finish and tolerance requirement
- Functional requirement of the component
Let me explain each of these points in simple plain english.
#1 Volume of production
For more volume of production, we need more machines and that machines should be capable of producing more volume of components or products.
Hence, for the production of more volume of components, the machines or the manufacturing process should be selected in such a way that it can produce more components in a given time period.
#2 Type of component
Various types of components are produced in the industries.
Some finished products require more strength or some require less strength.
Also some components have less density and some have more density.
For example aluminum has less density while iron, steel, etc have more density.
So based on the different properties as well as type of the component, the manufacturing process is selected.
#3 Expected quality standards
In the manufacturing process, there are few quality standards set for the particular product.
For example, few products require very high strength (like forged steel) while some require less strength (like cast iron).
So for these types of required qualities, the manufacturing process is selected accordingly.
#4 Properties of component
Various manufactured products require different properties for their specific applications.
For example, stainless steel used for utensils has different properties as compared to iron used in blacksmithy.
Hence, according to the required properties of the products, the manufacturing process is selected.
#5 Technical viability of the process
As discussed above, for the manufacturing of different components, the different processes are used.
For all such processes, the technical capability should be fulfilled.
The cost of the products is the most important factor while selecting the manufacturing process.
The manufacturing process that gives the good desired quality of product with least cost is selected.
#7 Rate of production
Machines and automation techniques in industries produce more products as compared to humans.
There are various production processes which can give more quantity of production as compared to other processes.
Such manufacturing process should be selected for that product.
#8 Limitations of shape and size
The size and shape of the workpiece are also a factor for the selection of manufacturing process.
For example, sometimes there can be a need of machining a large workpiece or sometimes it’s a machining of a small workpiece.
For such a large workpiece, the selection of production process should be such that it can handle the large workpiece. And vice versa for the small workpiece.
#9 Surface finish and tolerance requirement
Many products need a good finishing according to their specific applications.
For achieving a good surface finish on the components, there should be proper machining operations required to be done on that component.
Based on such finishing and tolerance the machining process is selected.
#10 Functional requirement of the component
Various components are used in different working environments.
For example, the engine cylinder, crank shaft, etc of the vehicle engine works in the high temperature environment.
While the alloy wheels of the vehicle do not face such high temperatures.
So based on such functional requirements, the manufacturing process is selected which can give proper strength and durability to the final product.
