The same physics that makes internal corners impossible to cut square also makes corner radius a direct lever on cost — smaller radius, smaller tool, slower cut, higher price. Quick summary: Internal corner radius on a CNC part is limited by the diameter of the...

The sales pitch for 5-axis is that it does everything in one setup. That’s true. What the sales pitch doesn’t mention is that 5-axis programming takes longer, the machine costs more per hour, and a lot of parts that get quoted on 5-axis would be cheaper on a 3-axis...

Most CNC quotes arrive as a single number per part — unit price times quantity, done. That works fine for simple commercial jobs. Aerospace quotes are different. They may break the cost into line items because different parts of the cost behave differently: some are...

The single biggest sticker shock in aerospace machining isn’t the material or the machine time. It’s everything around them — the compliance documentation, the first-article inspection, the material certification, the ITAR overhead, the NRE for fixturing a part...
