How To Choose The Best Metal For Your CNC Machining Parts?

The material is the "skeleton and muscle mass" of a part. In metal CNC machining, material selection is a functional consideration, to be sure, but it also directly relates to the complexity involved in processing and ultimately costs. The material choice can be the key to success or failure for a project, so a selection must be made that meets both functional and practical needs.

Common Metal Materials	Key Benefits	Uses
Aluminum Alloy	Light weight, easy to machine, moderate cost	Electronic device housings, automobile parts
Titanium Alloy	High specific strength, good biocompatibility	Aerospace components, medical implants
316 Stainless Steel	Corrosion-resistant and Strong	Marine equipment, medical equipment

Define Material Requirements based on Application Scenarios

• Strength and weight considerations: The strength and low weight of aerospace parts require the material to be made from titanium alloys, on the contrary, an electronics case could be made from aluminum alloys because it has to be strong yet lighter.
• Environmentally tolerant requirement: For implants of medical devices, biocompatible materials like stainless steel alloys of titanium are needed, for marine equipment, corrosions-resistant materials like 316 stainless steel are required as marine environments are severe.

Machining Performance and Cost Practical Considerations

Differences in processability: Aluminum alloys are easy to machine at high speeds, but Inconel alloys need to be machined at low speeds and with high power, which leads to increased tool wear and machining time.

Total Cost of Costing: Rather than just looking at unit costs per piece of the material, look at overall costs. For example, a slightly higher-cost material with higher machinability may bring down the final CNC machining price.

Golden Rules of Geometric Design

• Internal Corners And Tool Rounding: Do not create too small of corners with internal fillets, they need to be cut with small tools, which lack rigidity to perform well. It is desirable that the corners correspond to the tool radius as closely as possible.
• Aspect Ratio and Rigidity: Deep holes and tall sides create difficulties for rigidity, resulting in poor surfaces and large errors in size. It has to be ensured that the aspect ratios of the features are in a reasonable range for good processing performance.

Design for Precision and Assembly

• Clear Datum System: The design phase should establish a clear machining and inspection datum system to simplify the machining process and ensure proper positioning of CNC machining parts.
• Standardization/Simplification: Standardization of drill bit sizes can ensure that similar features can be clamped together. Reduced numbers of clamping result in less chance of errors and thus less expensive CNC machining services.
