CHEMICAL MACHINING FROM ANOTHER VIEWPOINT.

This paper uses the statistical tool of analysis of variance to look at the recommended operating values for chemical machining. The results obtained agree in general with those published by The Chem-Mill Division of Turco Products Inc., except that there was an indication of some deterioration of surface finish when using sodium aluminate in the solution. The results obtained should not be used in general, but only applied where the material arid method are comparable to the one used in the study. [ABSTRACT FROM AUTHOR]
