I am cutting 6 DP gears with older manual style Barber Colman type A machines. The material is 1117. The quantities are 100 or so each run. 30 teeth and 18 teeth. How many passes should I be taking? I am taking two cuts now. What speeds and feeds would get me the best results? I am at 60 rpm and .030 feed
