CNC cutting: refers to the CNC flame, plasma, laser and water jet cutting machine, CNC cutting nesting software provides the optimization set of material cutting procedures are full, automatic, efficient, high quality, high utilization rate of NC cutting according to the. CNC cutting represents the modern high-tech production methods, is the advanced optimization of the set of material calculation technology and computer numerical control technology and cutting the product of the combination of mechanical.

　　CNC cutting advantages: the numerical control software through the computer graphics, part of the optimization of the set of materials and numerical control programming, effectively improve the steel utilization, improve the efficiency of the production of cutting production. CNC cutting machine CNC system that is provided by the cutting technology, cutting technology and automatic control technology, effective control and improve the quality of cutting and cutting efficiency.

　　Disadvantages of CNC cutting: CNC cutting due to the higher cutting efficiency, nesting programming is more complex, if not used or did not use good nesting optimization programming software, steel waste will be more serious, resulting in more finely fast, sliced more, waste more. Numerical control system is the controller is the heart of CNC cutting machine, if there is no good use of CNC system, or is CNC system does not have the proper cutting technology and cutting experience, resulting in cutting quality problems, thereby reducing the cutting efficiency, resulting in steel waste, they also lose the numerical control cutting automation, high efficiency, high quality and high utilization rate of advanced sex.
