The manufacturing process of today involves many challenges from mass production down to lot size one. The CNC controls in factories must master this market trend specifically without an adequate amount of skilled labor in the US manufacturing world. In essence, manufacturing is facing a Renaissance in the CNC control technology shift.
On one hand, many of the current CNCs used in factories are controlling machines with 3-axis motion or maybe 3+1 and relying on a CAM program to provide the right machine code (e.g., G-codes) to drive these machines. An operator just pushes the green button to start a program. When one operation is done, he stops the machine, repositions the part (or a cobot) and pushes the green button again to start the next machining program. This type of operation bears a few risks.
