The largest opportunity varies by part, so the supplier should identify the operation or requirement driving the quote.<\/p>\n<h3>Does using a three-axis machine always cost less?<\/h3>\n<p>No. A three-axis machine may have a lower hourly rate, but multiple setups and fixtures can increase total cost and datum-transfer risk. A multi-axis route can be more economical when it completes more features in one controlled setup.<\/p>\n<h3>Should I loosen every tolerance to reduce price?<\/h3>\n<p>No. Loosen only requirements that do not protect function, assembly, safety, or compliance. Keep critical features clearly controlled and measurable. A functional tolerance strategy is safer than applying either extremely tight or extremely loose limits across the entire drawing.<\/p>\n<h3>Can ordering more parts lower the unit cost?<\/h3>\n<p>Often, because programming, setup, fixturing, and first-part work can be distributed across more units. However, material, cycle time, finishing, inspection, inventory, and revision risk remain. Compare realistic quantity breaks rather than ordering excess parts solely for a lower unit price.<\/p>\n<h3>What information should I send for a cost-reduction review?<\/h3>\n<p>Send the current CAD model and drawing, quantities, material and finish, critical interfaces, inspection requirements, delivery needs, and a note identifying what can or cannot change. That context helps engineering teams reduce process burden without weakening the part\u2019s intended function.<\/p>\n<\/section>\n<\/article>","protected":false},"excerpt":{"rendered":"<p>If a CNC quote is too high, the first question is not how much the supplier can discount\u2014it is which drawing requirement forces extra setups, smaller tools, longer inspection, or higher scrap risk.
