No need to know the vocabulary first
A few words, explained
- CAM
- Computer-aided manufacturing: software used to prepare the machine's cutting movements.
- CNC
- Computer numerical control: a computer directs a cutting machine.
- Workholding
- The way you keep a piece securely in place while working on it.
- Overhead
- Everyday business costs, such as rent, that need to be covered by the work you sell.
- Margin
- The amount left after the included costs, expressed as a percentage of the selling price.
Price the pre-machine work
Include design review, CAD or CAM changes, nesting, programming, tool selection, fixturing, proofing, and setup. These steps often matter more than cycle time on one-off work.
Use a visible machine and labor cost
Machine ownership, maintenance, dust collection, tooling, power, labor, and shop space need a recovery method. Define the rate before the quote instead of guessing after the job.
Separate repeat work from first-time work
A reusable file may reduce future setup, but it does not erase loading, material handling, workholding, inspection, cleanup, or the risk of a changed part.

Apply this reference to your project
Use your own project measurements and record how the result affects the material, setup or estimate.
- Name the material, dimension, or cost input that affects the decision.
- Use the reference and related calculator to check the measurement or estimate.
- Test or compare the result before committing final material, time, or client scope.

Common questions
How do I estimate CNC machining cost?
List programming, setup, material handling, machine time, labor, tooling, operating cost, cleanup, and profit separately so each cost is included and can be checked.
Does CNC cycle time include setup?
No. Setup, fixturing, tool changes, proofing, loading, unloading, and cleanup are separate tasks that should be estimated deliberately.
How should repeat CNC work be priced?
Use actual data from the first job to reduce only the work that becomes more efficient. Keep recurring handling, machining, inspection, and operating costs visible.
