CNC Milling Process for Custom Part Manufacturing

CNC milling uses computer-controlled rotating cutting tools to remove material from a stationary workpiece. By moving the cutting tool or workpiece along multiple axes, CNC milling produces flat surfaces, pockets, slots, holes, contours, and complex 3D geometries with high precision. It is widely used for prototypes, functional components, molds, fixtures, and production parts across various industries.

Typical CNC Milling Process:

よくある質問

At YP-MFG, we have a variety of CNC milling machines to meet diverse manufacturing needs. Our inventory includes 3-axis, 4-axis, and 5-axis CNC milling machines.

The 3-axis machines are perfect for simple operations, handling basic cutting tasks along the X, Y, and Z axes.

Our 4-axis machines add an extra rotational axis, allowing for more complex geometries and more efficient production of parts with features that require continuous machining around a fourth axis.

Finally, our advanced 5-axis CNC milling machines offer the highest level of precision and versatility, enabling the creation of intricate parts with complex shapes and angles.

These machines are capable of machining in five different axes simultaneously, reducing the need for multiple setups and ensuring exceptional accuracy and quality in every component we produce.

Our CNC milling tolerances depend on machine type, material, and part geometry.

  • Standard tolerances follow ISO 2768-m (metals) and ISO 2768-c (plastics)

  • Typical general tolerances: ±0.1 mm

  • High-precision 5-axis milling can achieve tolerances as tight as ±0.01 mm for critical features

For tighter tolerances, we recommend specifying requirements directly on the drawing so our engineers can optimize tooling, inspection, and cost.

  • 3-axis milling is ideal for simple geometries and flat features

  • 4-axis milling enables machining around multiple sides with fewer setups

  • 5-axis milling is best for complex geometries, tight tolerances, and parts requiring multi-angle machining

Choosing the right axis configuration can significantly reduce lead time and improve accuracy.

Lead times depend on part complexity and machining axis:

  • Simple 3-axis parts can be delivered in as fast as 1 day

  • Most CNC milling projects are completed within 5 business days

CNCフライス加工は、複雑な形状、溝、ポケット、 および輪郭の加工に最適である一方、CNC旋盤加工は、シャフトやブッシュなどの円筒形部品の加工に最も適しています。

部品に回転形状と直方体形状の両方が含まれている場合、 フライス加工と旋盤加工を組み合わせることが、最も効率的な解決策となる可能性があります。

Vertical CNC milling machines, with their vertically oriented spindles, are ideal for precision work on smaller components, offering excellent visibility and versatility for tasks like drilling and boring. Horizontal CNC milling machines, featuring horizontally oriented spindles, excel in handling larger, heavier workpieces and provide enhanced stability and efficient chip removal. For projects requiring extensive material removal and high durability, horizontal milling is preferred. In contrast, vertical milling is best for intricate, detailed work. Choosing between these types depends on your specific CNC milling services needs, whether for precision or bulk machining.

CNCフライス加工 is a subtractive manufacturing process where material is removed from a solid block using rotating cutting tools controlled by computer programs.

CNC milling is widely used to produce precision parts with complex geometries, tight tolerances, and consistent quality. It supports multi-axis machining (3-axis, 4-axis, and 5-axis), allowing features such as pockets, slots, holes, and complex contours to be machined efficiently.

At YP-MFG, CNC milling is commonly used for functional prototypes, low-volume production, and end-use parts across industries such as automotive, aerospace, and industrial equipment.

CNC mills can work with a diverse range of materials. Metals frequently used include aluminum, brass, and steel, each offering different properties for various applications. Additionally, CNC milling is effective on various plastics such as ABS, acrylic, polycarbonate, and polypropylene, which are valued for their versatility and ease of machining. This variety of materials allows CNC mills to be employed in numerous industries, from aerospace to consumer products, making them a highly adaptable tool for manufacturing.
The main difference lies in the spindle orientation. A vertical CNC milling machine positions the spindle above the workpiece, making it well suited for face milling, pocket machining, drilling, and general-purpose machining. It is the most common choice for prototypes and low- to medium-volume production. A horizontal CNC milling machine uses a horizontally mounted spindle, allowing chips to evacuate more efficiently during heavy cutting. This configuration is often preferred for machining large parts, multiple-sided components, and high-volume production where faster material removal and improved productivity are important.

A CNC milling machine consists of several key components that work together to achieve precise machining results. The machine base provides structural stability, while the spindle rotates cutting tools at high speed to remove material. The worktable securely holds the workpiece and moves along the X, Y, and Z axes. Other essential components include the CNC controller, which interprets machining programs, the tool holder, automatic tool changer (ATC), coolant system, and workholding fixtures. Each component plays an important role in maintaining machining accuracy, surface quality, and production efficiency.

CNC milling uses a variety of cutting tools depending on the material and feature being machined. End mills are commonly used for profiling, pocketing, and slotting, while face mills quickly machine large flat surfaces. Ball nose end mills create smooth 3D contours and curved surfaces, and drills are used for hole making. Chamfer mills, thread mills, and specialty cutters are selected for specific machining operations. Choosing the proper cutting tool helps improve surface finish, dimensional accuracy, and machining efficiency.

Design for Manufacturability (DFM) focuses on creating parts that are easier and more economical to machine. Simple design changes—such as increasing internal corner radii, avoiding deep pockets, maintaining adequate wall thickness, and specifying standard hole sizes—can significantly reduce machining time and tooling requirements. Applying realistic tolerances only where necessary also lowers inspection costs. Optimizing a design before production not only reduces manufacturing costs but also improves part quality and shortens lead times.
