It is a broad term referring to various manufacturing processes you can use to manipulate or transform sheet metal into a useful product or structure.
Normally, it is these manufacturing processes that we call fabrication techniques.
The fabrication techniques include cutting sheet metal, bending sheet metal, shrinking sheet metal, assembling sheet metal, etc.
Sheet metal fabrication
Resources:
First, machining is a subset of metal fabrication operations.
However, machining is a more specific process, which refers to subtractive operations in the metal fabrication industry.
Meaning, it is the cutting away or removing material from the workpiece (main material), using different techniques such as grinding, cutting, drilling, etc.
For example, laser cutting sheet metal is a machining technique:
Resources:
The main benefits include:
Step 1: Define the type of product you want to fabricate &#; clearly state every aspect of the product you need. It should include the type of material, design, structure, type of finish, etc.
Step 2: Identify and hire a custom sheet metal fabrication company. It should be based on their sheet metal fabrication capability, experience, expertise, customer support, and reputation.
Step 3: Developing technical drawing and listing requirements for custom sheet metal fabrication
Step 4: Prototyping &#; making the first sample for you to check and verify whether they conform to your requirements.
Step 5: Mass sheet metal fabrication and finishing operations
Step 6: Quality inspection and verification
Step 7: Shipping finished parts or structures.
It is the use of modern and computerized manufacturing capabilities to transform a metal sheet into a useful end product accurately.
Here, the precision sheet metal fabricating companies use CAM/CAD software for design, then incorporate computer numerically controlled machines (CNC) in the fabrication process.
Furthermore, it also involves the use of modern finishing and quality testing operations.
With precision sheet metal fabrication, a manufacturer can achieve tight tolerances.
Resources:
You can make thousands of products through sheet metal fabrication such as:
Sheet metal fabrication products
i. Metal tank
ii. Machine parts
iii. Ventilation systems
iv. Metal mailbox
v. Electrical enclosure
vi. Metal cabinet
vii. Portable shops
viii. Electronic parts, etc.
i. Stainless steel sheet metal &#; comes in different grades such as 304, 316, 410, 430, etc.
ii. Aluminum sheet metal &#; available grades include -H14, -H14, -H32, and -T6.
iii. Copper sheet metal
iv. Brass sheet metal
As you can see, the above classification is based on the type of material.
Again, the type of sheet can be classified depending on specific requirements.
Furthermore, you can classify these metals depending on the manufacturing process.
For instance, you can have corrugated sheet metal, galvanized sheet metal, cold rolled sheet metal, hot rolled sheet metal, etc.
Resources:
Choosing a specific metal fabrication design software will depend on your preference.
For instance, if you want automatic bend calculations, SolidWorks can be a perfect choice.

Still, you can consider the following:
i. Type of product you want to fabricate, such as electrical enclosure, letterbox, tanks, etc
ii. Metal sheet fabrication technique, it can be bending, welding, cutting, etc.
iii. Type of material
iv. Chemical and physical properties of the material
v. Sheet metal fabrication machinery and equipment
vi. Technical drawing for product to fabricate
vii. Dimensions such as bending radius, minimum flange width, wall thickness, etc.
viii. Tolerance
ix. Finishing operations such as painting, galvanizing, etc.
x. Compliance with set quality standards
It is where the metal sheet fabrication team, together with the client, examine the part design, manufacturing capability, and resources, to ensure the manufacturing will be cost effective and efficient.
Of course, it also takes account of the production needs (quantity), conforming set quality standards and clients requirements. Therefore, it examines:
It ensures that parts you fabricate parts fit and function properly.
Mostly, people use it to illustrate the quality of custom sheet metal fabrication process.
Please note: Tighter tolerances makes custom metal sheet fabrication more challenging hence, may require more advanced machine and equipment.
Besides, it may increase the cost of the sheet metal fabrication process.
Also, a single part that requires more fabrication cycles may compromise tolerance.
Therefore, it requires a strict and meticulous custom sheet metal fabrication procedure.
Moreover, in custom sheet metal fabrication, the tolerances mainly focus on:
