Precision micro-engraving of glass by automatic boundary tracking of complex images

초록

"Design is important in the IT, digital appliance, and auto industries. Aesthetic and artistic images have been applied for better quality of products. 2.5D engraving of glass products is important to fabricate aesthetic patterns in the jewelry industry. Grinding, laser and chemical methods have been used to fabricate jewelry. However, to improve productivity and quality of 2.5D machining on the glass, micro engraving through micro end-milling is required. In this paper, to improve productivity and quality of 2.5D machining on the glass, 2.5D engraving method has been developed through the ABT (Automatic Boundary Tracking) algorithm and glass machining technique. In addition, to obtain optimum cutting conditions in glass machining for jewelry, micro ball end-milling processes with crack free conditions are studied through Taguchi method. Performance of the developed system is verified through case studies.
