Design and process analysis: use CAD software to design the 3D model of the part, carry out processability analysis, and clarify the size, shape, surface roughness and tolerance requirements.
CAM programming: import the CAD model into the CAM system, plan the tool path, set cutting parameters (such as spindle speed, feed rate, depth of cut, etc.), to generate G-code programme.
Machine setup and test cutting: choose the appropriate CNC machine (such as CNC lathe, CNC milling machine, etc.), clamp the workpiece, install the tool, zero calibration, and test cutting and simulation to verify the correctness of the program.
Formal machining and post-processing: After formal machining, surface treatment, inspection and measurement are also required to ensure that the machining quality meets the design requirements.
This process ensures standardisation and precision from design to finished product.

3. Key technical parameters
Successful CNC services are dependent on the precise control of the following key parameters:
Spindle speed and cutting speed: depending on the diameter of the workpiece and material characteristics, the appropriate cutting speed is determined to ensure machining efficiency and tool life.
Feed rate: the speed at which the tool or workpiece moves, which directly affects surface quality and cycle time.
Cutting depth and back eating amount: the amount of material removed by each cutting needs to balance the machining efficiency and precision of the parts, to avoid vibration or heat accumulation caused by too deep cutting.
Cutting fluid use: Choosing the right cutting or cooling fluid can reduce temperatures, minimise tool wear and improve the machined surface.
Detailed parameter selection usually relies on cutting volume manuals and test cut data.
