Process
This is a fundamental difference between fabrication and machining. Fabrication starts with raw materials, such as sheet metal, plastic, or composite materials. These materials are then shaped and assembled to create a finished product. Machining, on the other hand, starts with a workpiece that is already close to the desired shape. The machining process removes material from the workpiece to create the desired shape.
The choice of whether to use fabrication or machining depends on a number of factors, including the type of material being used, the desired accuracy and precision, and the cost. Fabrication is typically less expensive than machining, but it can be more difficult to achieve high levels of accuracy and precision. Machining is more expensive than fabrication, but it can achieve very high levels of accuracy and precision.
Here are some examples of how fabrication and machining are used in different industries:
- Automotive industry: Fabrication is used to create body panels, while machining is used to create engine components.
- Aerospace industry: Fabrication is used to create aircraft fuselages, while machining is used to create aircraft engines.
- Construction industry: Fabrication is used to create steel beams, while machining is used to create precision tools.
Understanding the difference between fabrication and machining is essential for making informed decisions about which process to use for a particular project.

Ultimately, the choice of whether to use fabrication or machining depends on a number of factors, including the type of material being used, the desired accuracy and precision, and the cost.
Accuracy
Accuracy and precision are two important factors to consider when choosing between fabrication and machining. Accuracy refers to the degree to which a measurement or process conforms to a standard. Precision refers to the degree to which a measurement or process can be repeated.In general, machining is more precise than fabrication. This is because machining uses computer-controlled tools to remove material from a workpiece, which allows for very precise control over the dimensions of the finished product. Fabrication, on the other hand, often involves manually shaping and assembling materials, which can lead to slightly less precise results.However, it is important to note that fabrication can still achieve high levels of accuracy. For example, a fabricator can use jigs and fixtures to ensure that parts are assembled precisely. Additionally, some fabrication processes, such as laser cutting, can be very precise.The choice between fabrication and machining depends on the specific requirements of the project. If high levels of precision are required, then machining is the better choice. However, if high levels of accuracy are acceptable, then fabrication may be a more cost-effective option.Here are some examples of how accuracy and precision are important in different industries:
- Automotive industry: In the automotive industry, accuracy and precision are important for ensuring that parts fit together properly and function correctly. For example, the pistons in an engine must be machined to very precise tolerances in order to ensure that they fit properly and do not cause the engine to seize up.
- Aerospace industry: In the aerospace industry, accuracy and precision are important for ensuring that aircraft are safe and reliable. For example, the wings of an aircraft must be fabricated to very precise tolerances in order to ensure that they can withstand the forces of flight.
- Medical industry: In the medical industry, accuracy and precision are important for ensuring that medical devices function properly and do not harm patients. For example, the needles used to deliver injections must be fabricated to very precise tolerances in order to ensure that they do not break or cause pain to the patient.
Understanding the difference between accuracy and precision is essential for making informed decisions about which process to use for a particular project.
| Characteristic | Fabrication | Machining |
|---|---|---|
| Accuracy | Can achieve high levels of accuracy, but is typically not as precise as machining | Can achieve very high levels of precision |
| Precision | Typically not as precise as machining | Can achieve very high levels of precision |
| Cost | Typically less expensive than machining | Typically more expensive than fabrication |
| Applications | Used in a wide range of industries, including automotive, aerospace, and construction | Typically used in the metalworking industry |
Cost
Cost is an important factor to consider when choosing between fabrication and machining. Fabrication is typically less expensive than machining, but there are a number of factors that can affect the cost of each process.
- Materials: The cost of materials is a major factor in the cost of fabrication and machining. Fabrication can be used with a wide variety of materials, including metals, plastics, and composites. Machining is typically used with metals, but can also be used with other materials, such as plastics and ceramics. The cost of the material will vary depending on the type of material, the quantity required, and the availability of the material.
- Complexity: The complexity of the part is another factor that can affect the cost of fabrication and machining. Fabrication is well-suited for creating simple parts, while machining is well-suited for creating complex parts. The more complex the part, the more time and effort it will take to fabricate or machine the part, which will increase the cost.
- Quantity: The quantity of parts being produced can also affect the cost of fabrication and machining. Fabrication is more cost-effective for producing small quantities of parts, while machining is more cost-effective for producing large quantities of parts. This is because the setup costs for fabrication are typically higher than the setup costs for machining.
- Labor: The cost of labor is another factor that can affect the cost of fabrication and machining. Fabrication is typically more labor-intensive than machining, which can increase the cost of fabrication. However, the cost of labor can vary depending on the location of the manufacturing facility and the availability of skilled labor.
In general, fabrication is less expensive than machining for simple parts, small quantities of parts, and when the cost of labor is low. Machining is more cost-effective for complex parts, large quantities of parts, and when the cost of labor is high.
