ABSTRACT:
To maintain the actual milling rate of a chemical milling solution within a predetermined range, an automated chemical milling controller periodically measures the actual milling rate within the milling tank, senses the actual temperature of the milling solution, and calculates the normalized milling rate and desired amounts of feedstocks necessary to maintain the milling rate within a predetermined range. The controller automatically adds the desired amounts of feedstocks to a milling solution.
