How to reduce CNC machining costs

Design for machinability

Loosen non-critical tolerances (each decimal place multiplies cost), radius internal corners to standard tool sizes, avoid deep narrow pockets, and keep features reachable in one or two setups. DFM feedback before quoting saves both sides money.

Batch and stock strategy

Setup amortization means quantity 10 can cost 40% less per part than quantity 1 - batch your own repeat parts too. Near-net stock (sawed blanks, extrusions, castings) cuts removal volume and cycle time together.

Machine utilization

Unattended hours are the cheapest hours: reliable workholding, chip management and conservative-but-stable parameters let one operator run multiple machines or lights-out shifts.

Quote-side savings

Fast, accurate quoting wins better-fitting jobs - work priced right beats work won by underpricing. Automate the first-pass quote and spend saved hours machining.
