Many CNC controllers has been designed and employed in CNC machinery during recent years but all of them has some limitations and disadvantages due to their design and used methods. The purpose of this research is designing and modifying a novel multi axis automatic controller (MAAC) for using in CNC machinery which has more advantages compared with used controllers and has an optimized performance. By using MAAC in CNC machinery we can achieve more machining speed and repeatability in a shorter time in implementation of industrial process.
