What is cnc milling
CNC milling can be understood in two parts: CNC and milling. CNC stands for computerised digital control, where only the programming needs to be written and the computer automatically controls the tool and workpiece movement, which does not require manual control. Now we come to milling, which is a process that uses machine driven tool rotation combined with workpiece movement to remove excess parts of the workpiece. In this we can take out the initial workpiece and use the cutting tool to constantly remove material from the workpiece at different positions. In order to reach these different positions, the workpiece is continuously rotated.
Milling has the advantage of high efficiency, precision and quality. The time and personnel costs can be reduced and parts of all shapes and sizes can be machined.
The process of milling
Firstly, a CAD model needs to be created for the part you want, either 2D or 3D depending on your ideas.
Then the program has to be set up in the CNC milling machine, according to the milling machine there are different set up steps.
Once the setup steps have been completed, the operator can execute the cnc machine program. The entire milling process will then be completed automatically and after the execution is complete the machine will create the required part.
Inspection of milled parts
All CNC milled parts are first visually inspected, using other hand-held gauges such as calipers or micrometers to check the key dimensions are standard. We also use a number of QC instruments to carry out the measurement.
