Abstract : The art of chemical metal removal is by no means new. It has been used by photoengravers for decades in the preparation of printing and engraving plates. This technique has also been used in the fabrication of decorative metalwork and nameplates. The latest innovation is the processing of the etched printed circuit; however, only within recent years has the potential of chemical metal removal been recognized. In spite of the tremendous advantages the process has to offer, its use has been limited to only a few applications; but as the equipment and know-how are becoming more readily available, the use of chemical milling as a production metal removal process is now taking its place as a specialized metalworking process. With the demands for special hardware in satellite and other space applications steadily increasing, designers find they can satisfy many of these demands with the aid of chemical milling. (Author)
