The practical function of laser cutting machine design is reflected in the continuous development and gradual improvement. Combined with the consumer psychology and physiological needs of contemporary people, a more practical laser cutting machine that is more in line with factory production is designed, and the design direction is more practical and functional.
  
  the content of practical function analysis refers to the main functions and auxiliary functions of the laser cutting machine, as well as the identification, use and operation difficulty of the functions. The designer is required to understand the user's feelings in the whole process from contact with the laser cutting machine to use to final evaluation, and compare the advantages and disadvantages of similar laser cutting machines, so that he can avoid those mistakes while designing. For laser cutting machines with complex internal mechanisms, sometimes the appearance of the laser cutting machine can be removed and its essential attributes and functions can be analyzed.
  
  at this stage, we should try to avoid paying too much attention to the aesthetic characteristics of the laser cutting machine and ignoring the basic functions of the laser cutting machine. A laser cutting machine (except for decorations) cannot be called a laser cutting machine if it does not have practical functions; Similarly, laser cutting machines that only have the basic functions of laser cutting machines, but do not have aesthetic characteristics, will not be liked by consumers, and will lose competitiveness in many similar laser cutting machines until they are finally eliminated by the market.
