CNC Machining Design Guidelines
Follow these BaoSheng expert guidelines to improve how efficiently you produce things. To improve the accuracy of parts, reduce delivery times, and lower the costs of production and rework, follow these recommended practices.
Part Size & Envelope
Milling: up to 4000mm x 1500mm x 600mm.
Turning: up to 200mm x 500mm.
3-axis milling machines are suitable for large structural components, while multi-axis (4/5-axis) machines handle more complex geometries.
Feature Alignment
In 3-axis machining, it is recommended to align holes and features on a single plane whenever possible.
Multi-surface machining requires multiple setups; aligning features reduces machining time and eliminates cumulative errors.
Fillets
Internal fillet radii should exceed 1/3 of the cavity depth to prevent tool damage and reduce chatter.
Wall Thickness
Metal Parts: Baoseng can achieve minimum wall thicknesses as low as 0.5mm.
Plastic Parts: A minimum wall thickness of 1.0mm is recommended to prevent vibration and deformation during processing.
Holes & Threads
The hole diameter and thread diameter should match standard drill bits and threading tools. The hole depth should generally not exceed 10X the diameter.
For holes with diameters between 1.5mm and 5mm, the recommended tapping depth is 3X the diameter.
Cavity Depth
To minimize chatter, tool deflection, and other issues, the depth of machined cavities should not exceed 4X their width.
Undercuts
The chamfer width of T-slots is approximately 3–40 millimeters. Dovetail slots achieve optimal results with chamfers at standard angles of 45 degrees or 60 degrees.

FAQs About CNC Machining
What is CNC Machining?
CNC (Computer Numerical Control) machining is a precision automated manufacturing process that uses programmed cutting tools to directly fabricate metal and plastic parts based on 3D CAD models.
Upon receiving your 3D CAD model, BaoSheng’s experienced operators will program and optimize toolpaths to ensure tight tolerances while minimizing costs.
What are the advantages of CNC machining?
CNC machining offers high precision and versatility compared to 3D printing, injection molding, and laser cutting. It consistently achieves stringent tolerances as tight as 0.01mm and surface roughness as low as Ra0.8, making it the most cost-effective solution for processing everything from simple substrates to complex functional parts.
By utilizing 0.05mm micro-tools and precision five-axis machining centers, Baosheng Industry tackles extreme dimensional challenges—from micro-components to large structures—while ensuring exceptional part quality.
What are the challenges of CNC machining?
CNC machining offers exceptional cost-effectiveness for simple geometric parts, while complex features typically require multi-axis setups, increasing production time and costs. Physical tool contact and angular limitations constrain design flexibility.
As a subtractive manufacturing process, it generates material waste. However, the cost of raw metal or plastic blocks is generally far lower than the powder required for additive manufacturing, effectively offsetting the expense of waste.
What materials are suitable for CNC machining?
CNC machining is suitable for a wide range of materials, including metals (such as aluminum, steel, and copper), plastics (such as ABS and polypropylene), and composite materials. The most appropriate material for processing can be selected based on customer requirements.
How long does CNC machining parts take?
The standard delivery time is between 3-10 days, depending on the complexity of the part, the availability of the material, and the quantity ordered.
Can you offer CNC machining DFM?
Yes. Upon receiving your enquiry, our engineers will review it promptly and provide any necessary recommendations for optimising the processing. This approach improves the quality of production parts while keeping manufacturing costs under control.
