Chemical Bath Life Forecast
Chemical baths are used to clean titanium parts coming from the etching process. Chemical process tanks have a finite cleaning capacity which necessitates periodic draining & recharging with new chemical to achieve processing requirements. Current forecasting tools are based on historical usage rates and are not dynamically responsive to production increases, considering defined chemical parameters. Current QA chemistry monitoring is not predictive of bath life resulting in unplanned tank refill, increased cost, as well as schedule impact (both operations & maintenance). The student team was tasked with developing a system to track the number of parts processed through each specific tank on a weekly basis to provide a more robust forecasting of chemical solution bath life correlated to, or directly determined by, production rates.
