This invention is to form engraved and embossed patterns on glass frame. Its machining processes are following: Fix glass frame under intermediate process on CNC lathe with press mold for machining inner and outer surface, then form lens fixing grooves by programmed CNC machine, and place those machined glass frame press mold for machining outer sirface, and input program into CNC machine so that engraved and embossed patterns can be created, consequently as tool advances by the program thus creating engraved and embossed patterns in machining outer surface.
