CNC machining, or computer numerical control machining, is a highly automated manufacturing process that utilizes high-speed cutting tools to create precise designs from metal or plastic stock. Standard CNC machinery encompasses 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. The machining process can involve various configurations, such as stationary workpieces with moving tools, rotating and moving workpieces with stationary tools, or simultaneous movement of both cutting tools and workpieces.
Skilled machinists operate CNC machines by programming tool paths based on the geometry of the desired machined parts, often derived from computer-aided design (CAD) models. CNC machines excel in precision and repeatability, making them capable of machining nearly any metal alloy or rigid plastic with exceptional accuracy. This versatility makes custom machined parts suitable for diverse industries, including aerospace, medical, robotics, electronics, and industrial sectors.
Fuyu offers comprehensive CNC services and custom CNC quoting for a vast selection of materials, encompassing both common materials like aluminum and acetal, as well as advanced materials such as titanium and engineered plastics like PEEK and Teflon.

CNC Machining Design Guidelines
| Feature | Description | Details & Considerations |
|---|---|---|
| Internal Corner Fillets | Rounded transitions between internal corners to enhance strength and prevent stress concentration. | Design fillets with radii 0.020″ – 0.050″ larger than the standard drill size used for their creation. Maintain a drill diameter to depth ratio of 1:6 (recommended: 1:4) as a guideline for internal corner radii. This ensures proper tool access and avoids potential undercuts or tool breakage. |
| Floor Fillets | Rounded transitions at the base of features to improve flow and prevent sharp edges. | Design floor fillets with radii smaller than internal corner fillets to allow the same tool to clear material from the interior. This minimizes tool changes and optimizes machining efficiency. |
| Undercuts | Recesses or depressions designed into a part for functional or aesthetic purposes. | Always design undercuts using standard dimensions and away from corners to ensure accessibility for the cutting tool. This prevents tool interference and maintains dimensional accuracy. |
| Tapped/Threaded Hole Depth | Depth of a threaded hole for fastening components. | Provide tool clearance slightly beyond the tapped hole depth to ensure complete threads. This allows for proper tool engagement and avoids incomplete threads. |
| Complexity | Overall complexity of the design, impacting manufacturing costs. | Minimize the number of small cuts to reduce CNC machining costs. Design only essential features, balancing functional requirements with aesthetic considerations. This optimizes machining time and reduces material waste. |
| Material Selection | Choice of material based on application requirements. | Consider factors such as strength, machinability, and cost when selecting materials. Choosing materials with good machinability will reduce machining time and costs. |
Advantages and Challenges of CNC Machining
Precision and Repeatability: CNC milling and turning excel in delivering high accuracy and repeatability. Tight tolerances between +/-0.001″ – 0.005″ can be achieved, ensuring consistent part quality. This precision is crucial for applications demanding tight tolerances, such as aerospace, medical, and electronics industries.
High-Volume Production & Flexibility: CNC machines can be programmed to operate continuously, enabling high-volume production runs. This makes CNC machining ideal for producing parts on demand, meeting both one-off and high-volume requirements. From custom prototypes to production runs exceeding 10,000 units, CNC machining provides the flexibility to scale production as needed.
Rapid Turnaround: CNC machining offers a rapid turnaround, enabling parts to be produced within a day, with delivery within a week. This speed is crucial for projects with tight deadlines or urgent needs.
Preserving Material Properties: Unlike processes like injection molding or additive manufacturing, CNC machining removes material through cutting, preserving the inherent mechanical properties of the chosen metal or plastic. This ensures that the machined parts retain their desired strength, durability, and other critical characteristics.
Material Versatility: CNC machining is compatible with a wide array of materials, including over 50 industrial-grade metals, alloys, and plastics. From aluminum and stainless steel to PEEK and ABS, CNC machining offers flexibility in material selection, allowing for diverse applications and design possibilities.
Geometric Complexity and Tool Access: While CNC machining offers great precision, geometric complexity can impact cost and feasibility. Simple, robust designs are generally more cost-effective to machine. Tool access limitations can restrict the complexity of features achievable, though multi-axis machines (5-axis and above) offer greater flexibility in machining intricate geometries.
Initial Setup Costs: Setting up CNC machining can involve significant initial costs, including training, programming, and tooling. However, these costs are fixed, meaning they can be spread across multiple parts, becoming more economical with increased production volume. Minimizing part repositioning during machining also helps optimize cost-effectiveness.
Material Limitations and Processing Time: Some CNC machining methods, such as wire EDM, can be slower and more expensive than other methods. Additionally, wire EDM requires electrically conductive materials, limiting its application range.
