2.1 General Tolerances For Shape And Position
Types Of Multi-Axis CNC Milling
A CNC milling center or CNC mill can perform different operations based on the number of axes.
3-Axis Milling
the most basic type of milling operation, using three axes of motion including X, Y, and Z to machine a workpiece. 3-axis CNC milling is one of the most widely used manufacturing techniques for mechanical parts, it is ideal for milling parts with simple designs.
4-Axis Milling
a rotary table is added to the CNC machine, allowing the workpiece to be rotated around a fourth axis. This enables the milling of complex shapes and contours on the workpiece.
5-Axis Milling
a type of 5-axis machining, the machine has two additional axes of motion, typically a rotary axis (A) and a tilting axis (B). This allows the tool to approach the workpiece from multiple angles, enabling highly complex shapes for industries like aerospace, medical, etc.
Typical Stages Of CNC Milling Process
3Design
the first stage is to create a CAD model or blueprint of the part or product to be milled or machined, using computer-aided design (CAD) software, whether you want to design a 2D or 3D model.
Programming
after the design is completed, the next thing to do is convert your CAD model to a CNC program. Using the computer-aided manufacturing (CAM) software to generate G-code instructions to create a tool path that the machine follows for milling.
Setup
Before the mill machining actually starts, the milling machine needs to be set up with the required cutting tools, work holding fixtures, and other accessories needed to begin the machining process.
Execution
once the milling machine is properly set up, the equipment follows the tool path created by the CAM software to cut and remove material from the workpiece until the final shape is achieved.
After the CNC milling, we are also going to complete the required finishing operations and quality inspections to ensure product quality before shipment.

The CNC Milling applications involves the following industries (not limited to):
CNC Milling FAQs
Plane: CNC milling machines can be used to process various planes, including straight lines, arcs and various complex shapes.
Cam: The cam is a common part in machinery, and the CNC milling machine can be used to process various shapes of the cam.
Thread: CNC milling machines can be used to process a variety of threads, including precision threads and special-shaped threads.
Holes: CNC milling machines can be used to process holes of various shapes and sizes, including straight through holes, blind holes, inclined holes, etc.
Curved surfaces: CNC milling machines can be used to process various complex curved surfaces, including spherical surfaces, rotating surfaces and free-form surfaces.
Gears: CNC milling machines can be used to process various gears, including spur gears, helical gears, arc gears, etc.
In short, CNC milling machines can be used to process parts of various shapes and sizes, and have the advantages of high precision, high production efficiency, and stable machining accuracy.
Starting from designing a CNC milling part drawing or geometry with CAD software, then CAM software converts the file to CNC machine program, which can dictate the machine what to do and how to do. CNC milling services apply computerized technique to complete the manufacturing as the following basic production stages:
• Designing a CNC Milling CAD model
• Converting the CAD model into a CNC milling program
• Setting up the CNC milling machine
• Cutting small pieces off the block material to obtain approximate shape
• Executing the CNC milling operation with higher precision and accuracy
Turning operations are performed by rotating the workpiece and using a stationary cutting tool, and milling operations are performed by rotating the cutting tool and leaving the workpiece locked in place.
The most common materials used in CNC milling are metals such as brass, Titanium, aluminium or steel, and plastics such as PVC, ABS, polycarbonate and polypropylene.
In short, tolerances are measurements that signify the level of precision needed for a part that you want to manufacture. Specifically, machining tolerances indicate the degree of variation permitted in a part’s final dimensions or measured value.
Due to the rotational motion produced by CNC milling machine tools, visible tool marks will appear on the surface finish of CNC machined parts. If you require a smooth, blemish-free finish on your part, we recommend you choose polishing or a secondary surface treatment: granular surface treatment or powder coating.
