Cost & Manufacturability

What factors determine the price of a CNC machined part?

Price is shaped by programming/setup, number of setups, machining time, tooling, tolerance, finishing, inspection and quantity as well as raw material. Two parts of the same weight can therefore have very different costs.

Why does this matter?

Manufacturing cost is often the sum of small design decisions. Evaluating setups, critical tolerances, tool access, quantity and inspection early can preserve function while reducing cost.

What factors determine the price of a CNC machined part?

What should you check?

  • Material, surface condition and relevant material behavior
  • Machining method, tool/process stability and inspection steps
  • Number of setups, operation sequence and programming/preparation effort
  • Critical dimensions, tolerances and required accuracy level
  • Initial quantity and likely repeat or series-production volume

A practical evaluation sequence

Manufacturing cost is more than cutting time. Programming, setup, workholding, tooling, material, inspection, secondary processes and quantity all matter, and small design choices can change total cost significantly.

Common mistakes

  • Assuming part weight is the main driver of price
  • Comparing prototype pricing directly with repeat-production unit pricing
  • Missing the cost impact of unnecessary tolerances, deep pockets or special finishes
Decision rule

The safest cost reduction removes manufacturing difficulty that adds no functional value rather than randomly relaxing quality.

What should you send for evaluation?

  • 3D CAD/mesh data, revision status and required output format
  • Technical drawing, datums, dimensions and available measurement results
  • Material, surface condition and relevant material behavior
  • Initial quantity and likely repeat or series-production volume
