Net York trying to get subtractive manufacturing CNC mills to obey this is going to be a trick.

The controller just runs Gcode for positioning and speeds. They’d need to preprocess the gcode through an AI database to check if the path builds a gun part shape then allow machining or block it.

Inevitably somebody will just replace the controller with a home grown system.

And a CNC mill can still run manual cuts a single passes that may not appear to look like a part, when done separately

This is old clueless men trying to make laws about technology they don’t understand.
