How much does it cost to make a CNC machined part? The answer depends on a number of variables like the material type, part quantity, dimensional tolerances, lead time, and surface finish. We demonstrate this using the two shock bottom brackets we CNC machined for the landing gear on the DarkAero 1 prototype. They were made in house on our Tormach from 7075-T6 aluminum. Quoting tools from Xometry offer a quick and easy way to see the cost of machining these parts if we were to outsource them. We uploaded a 3D CAD file of the shock bottom bracket to Xometry and then looked at the instant quote numbers to see where the cost might land in production.
