Whats wrong with CNC machining?
Many machinists think that CNC machining wastes metal, and it’s difficult to argue with that in some respects. What’s left is metal shavings, which are fairly value-less in resale (even for scrap). In today’s steel-starved markets, that is significant. Forging uses most of the metal, by contrast. A bit of metal can seep into cracks between the tool and die.
