CNC - Computerized Numerical Control
People can have a bad day. Mistakes can occur and endanger the quality of the product. Another major source of error is the monotony of series production. If an operation has to be performed over and over again, the employee's concentration can drop after a few hours.
Computers don't know daily routines and can always do the same work, even when used continuously.
Errors are still possible, of course. CNC means Computerized Numerical Control. This means "machines controlled by computer programs" and these programs are still created by a person. Programming can be done directly in a programming language or by automatic conversion of CAD drawings.
Modern CNC machines are very versatile programmable. By automatically adjusting the limit stops, the material can be placed in the machine quickly and precisely. The laser cutting machines even automatically recognize the position of the workpiece. Furthermore, the tools are controlled by the machine in their movement, speed and force, which results in a very high precision of the products.
