CNC machining costs are primarily driven by material selection (40-60%), machine time (amplified by 5-axis complexity), and geometric tolerances (±0.025mm can increase costs 150%). Hidden expenses include tool wear (e.g., $0.38/min for titanium) and post-processing. To optimize:

1. Partner with factory demonstrating ISO-certified 5-axis precision (±5μm)

2. Demand operation-level cost breakdowns

3. Prioritize vendors offering scientific DFM feedback within 24h
   True cost efficiency comes from technical collaboration, not price negotiation – strategic partnerships reduce TCO by 18-32% through process innovation.
