Manufacturing Processes for Machined Parts
The manufacturing processes used in creating machined parts are diverse and can include the following:
CNC Machining
Computer Numerically Controlled (CNC) machining is one of the most common methods for producing precision parts. It uses a computer to control the movement of tools, allowing for high accuracy and repeatability.
Turning
Turning is a machining process where a rotating workpiece is cut by a stationary tool. This method is often used to create cylindrical parts and is particularly effective for producing shafts and fittings.
Milling
Milling involves the use of rotating cutting tools to remove material from a workpiece. It is versatile and can be used to create a variety of shapes and features in machined parts.
Forging and Casting
Forging and casting are traditional methods of manufacturing parts. Forging uses compressive forces to shape metal, while casting involves pouring molten metal into molds. Both processes can produce strong, durable components.
