Chemical Milling is a finishing process that removes oxide scale and alpha-case from forged titanium parts. To increase efficiency of chemical milling at Wyman-Gordon Company, we analyzed previous projects, assessed the etch quality of their chemical milling bath, and evaluated means of process control and potential areas of cost and raw material savings. Via our experimentation we determined that the ideal concentration of HF is 8% for all temperatures 90 degrees Fahrenheit to 120 degrees Fahrenheit to effectively etch a titanium part.
