CNC machining of precision parts demands high precision and tight tolerances to achieve complex geometries and excellent surface finishes. Materials like aluminum, stainless steel, and titanium are commonly used for their dimensional stability and performance. Advanced tooling and thermal management are critical to maintaining accuracy, especially for miniaturized components. These parts are essential in industries such as aerospace, medical devices, electronics, and automotive, where quality assurance is paramount.

1. Material Selection
Aluminum (e.g., 6061, 7075): Lightweight, excellent machinability, and good thermal conductivity.
Stainless Steel (e.g., 304, 316): High strength, corrosion resistance, and durability.
Titanium (e.g., Grade 2, Grade 5): High strength-to-weight ratio and corrosion resistance.
Plastics (e.g., PEEK, Delrin): Lightweight and electrically insulating, suitable for non-conductive applications.
Copper Alloys (e.g., C11000): Excellent electrical and thermal conductivity.
2. Machining Challenges
Tight Tolerances: Typically within ±0.01 mm or tighter.
Complex Geometries: Intricate designs with thin walls, small features, and tight clearances.
Surface Finish: Smooth finishes (Ra < 0.8 µm) are often required for functional and aesthetic purposes.
Thermal Management: Minimizing heat generation to prevent material distortion.
Material-Specific Issues:
Aluminum: Soft and prone to burrs.
Stainless Steel: Hard and abrasive, leading to tool wear.
Titanium: Low thermal conductivity, causing heat buildup.
Plastics: Low melting point and prone to deformation.
3. Tool Selection
Tool Material: Carbide or diamond-coated tools for durability and precision.
Tool Geometry: Sharp cutting edges and polished surfaces to reduce cutting forces and improve finish.
Coolant: Use water-soluble coolants or air blast for effective heat dissipation.
4. Cutting Parameters
Cutting Speed (Vc):
Aluminum: 200-500 m/min
Stainless Steel: 50-150 m/min
Titanium: 30-80 m/min
Plastics: 300-600 m/min
Feed Rate (f): 0.02-0.1 mm/tooth (lower for finer finishes).
Depth of Cut (ap): 0.5-2 mm (adjust based on material and tool rigidity).
Coolant: Essential to prevent overheating and improve tool life.
5. Surface Finish
Typical Ra Value: < 0.8 µm (often < 0.4 µm for functional surfaces).
Post-Processing: Polishing, anodizing (for aluminum), or coating for improved performance and aesthetics.
