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.

Ethics and rights aside, this isn’t even possible to comply with. The law applies to additive and subtractive manufacturing hardware, and expects it to automatically detect and refuse any attempts to manufacture a firearm. But that depends on an underlying assumption that a machine can answer the question “will this command (set) result in the construction of a gun?” And that assumption is false.
Even if you somehow designed an algorithm that could read a G-code program and determine whether it produces something shaped like a gun, it still wouldn’t be enough - because the CNC machine is just one step of a manufacturing process. The human operator controls what materials and commands go into the machine, so they also have full control over all inputs that the “oversight” program is allowed to see.
Some simple ways to bypass this (hypothetical and perfect implementation):
So even if this was something we wanted to enforce, it’s just not possible. For the same reason why Minecraft abandoned their plans for an SMP “penis detector”, this law could never be complied with because it’s impossible to build a machine that actually meets the requirements.
