CNC Machined Part
CNC machining is a subtractive manufacturing process since it starts with a block of material (metal or plastic mainly) and removes materials using different tools to reach the final shape.
The full name is Computer Numerical Controlled as the machines are following specific instructions programmed by an operator. Once the instructions are set, the production process doesn’t involve manual operators. There are two main processes for CNC machining: milling and turning. Most CNC machines work on 3 axis: X, Y and the Z. Sometimes, 3 axis is not enough to make complex geometries. More advanced machines are used, such as 4 axis or 5 axis, allowing the bed and or the cutting tool to move on additional on the A and the B axis.
Extremely accurate to guarantee quality
Since they manufacture machined parts using CNC technology. They are usually dependable. Notably, because of the three aspects of machining accuracy attributed to all CNC parts. These include the aspects of dimensional accuracy, positional accuracy, and shape accuracy. However, the size, shape, and surface of items processed under the same conditions may not be identical because of factors like machining tolerance.
Even though tolerance is unavoidable, it should be within the allowable range. Therefore, the factors that contribute to the tolerance of CNC machined parts need improvement. Through improving the design, the machining accuracy, and training of machinist controlling the CNC machine
