Abstract

The process consists of (a) covering the metal to be etched with a protective layer; (b) numbering the area(s) to be etched to define valves of the x, y co-ordinates of their perimeter(s); (c) automatically scoring the metal and coating with a scoring tool which cuts through the coating along the perimeters defined by the x, y co-ordinates; (d) removing the coating from the area(s) to be etched; and (e) immersing the partly-coated metal in an etching soln. for a predetermined period to remove a predetermined amt. of metal from the uncoated area(s). The metal is aluminium or its alloys, or titanium or its alloys, the etching bath is an alkali metal hydroxide or halogen acid, and the protective layer is a butadiene-styrene copolymer. EPAB- EP-179940 B An automated chemical milling process for metals, said process comprising the steps of: (a) coating the metal to be chemically milled with a resist coating; (b) digitising the area(s) to be chemically milled to define at least x and y coordinate values for the perimeter of the area(s) to be chemical milled; (c) automatically scribing the metal and coating with a scribing tool, said scribing tool cutting through said coating along the perimeter defined by the x and y coordinate values; (d) removing the resist coating from the area(s) to be chemically milled; and (e) immersing said partially coated metal into an etching solution for a predetermined period of time to remove a predetermined amount of metal from the uncoated area(s).
