The versatility of the milling process allows it to be used in a wide range of industries and for a variety of part designs, including grooves, chamfers, threads, and recesses. The most common CNC milling operations include:
face milling
Face milling is a milling operation in which the axis of rotation of the tool is perpendicular to the surface of the workpiece. Typically, face milling is used to create flat surfaces and contours on the finished part, producing a higher quality finish.
Form Milling
Form milling is a milling operation involving irregular surfaces and contours of parts with curved surfaces. The process uses form milling tools, such as convex, concave, and fillet tools.
Angular Milling
Angular milling is a milling operation in which the axis of rotation of the tool is at an angle to the surface of the workpiece. The process uses a single-angle milling cutter to produce angular features such as chamfers, serrations, and grooves.
Holes and threads
The use of fixed-size tools for drilling, reaming, reaming, boring and tapping, etc., generally, CNC milling has boring, drilling, and reaming functions.
Rapid prototypes or end-use parts
What is CNC Milling
CNC milling is one of the most commonly used machining methods in the machining industry. The workpiece is fixed on the worktable with a fixed fixture. The tool enters the workpiece at a certain angle, removes material from the solid workpiece, and forms various complex geometric shapes and parts by drilling or cutting, including plane milling and contour milling. It can also be used for drilling, reaming, threading, and tapping, reaming, boring, and thread processing. The tool is controlled by a special computer, which greatly improves reliability and repeatability while reducing the possibility of human error.
The CNC milling process works by the machine reading the coded instructions and then putting them into operation. It all starts with the development of a 3D CAD file representing the final part. The completed design is exported to a CNC-compatible file format and converted by the CAM software into a CNC machine program, usually in G-code format, which is then used as an instruction to guide every movement of the machine.
Before operators run the CNC program, they prepare the CNC milling machine, secure the workpiece to the table, and connect the milling machine to the machine spindle.
Once the CNC milling process begins, the machine begins to rotate the cutting tool at speeds up to several thousand RPM. Depending on the type of milling machine used and the requirements of the milling application, as the tool cuts into the workpiece, the machine performs one of the following operations to produce the necessary cut in the workpiece.
- The workpiece is slowly fed into the stationary rotating tool.
- Move the tool on a stationary workpiece.
- Move the tool and workpiece relative to each other.
In CNC milling, the machine usually rotates with the cutting tool to machine a movable workpiece. A complete part needs to be machined several times to achieve the required accuracy and tolerances.
CNC milling machines are usually defined by the number of axes they have. More axes mean that complex workpieces can be machined with high precision and a high-quality finish, such as medical parts or aerospace components.
3-Axis: Simple geometries can be cut vertically (Z-axis) and in the X and Y directions using a 3-axis milling machine. However, it is often not possible to use a 3-axis milling machine for undercuts. Therefore, more complex designs may require more sophisticated milling machines.
4-Axis: On the basis of the 3-Axis, a rotary axis is added, generally 360° rotation in the horizontal plane. Through the rotation can make the product realize the processing of multiple sides, greatly improve the processing efficiency, reduce the number of clamping, and improve the production efficiency. Suitable for processing some box-type parts, mold processing, etc.
5-Axis: For the highly complex design of the five-axis milling machine, in the four-axis above and then a rotary axis, generally upright surface 360 ° rotation, five-axis has been able to comprehensive processing can achieve a clamping, can reduce the cost of clamping, reduce product scratches and bruises, suitable for processing some multi-station hole and plane, processing precision requirements of high parts, especially the shape of the processing precision requirements more stringent parts, such as medical equipment and aerospace parts.
