By developing a high-quality plexiglass sign using LED, it is possible to respond to international competitiveness and effectively cope with market expansion measures. The degree of inhalation of the fine dust blown by the air nozzle was tested so that it was not blown into the air. As a result of this test, the acrylic absorption rate was 82%, an increase of 20% from 60% before improvement, and the working environment was improved. With the development of the dust extraction device for the acrylic processing machine in this study, the suction and removal of acrylic fragments or dust is smoothly performed, resulting in a cleaner, more hygienic and improved safety through the improvement of the working environment. As a result of comparing the amount of burr generated in the plexiglass material and comparing the degree of test performance for reaching 24,000 rpm, it reached 24,000rpm.
