Suppliers are working hard to make
sure their heat treating equipment is controllable, repeatable and efficient,
and manufacturers continue to incorporate technology that gives heat treaters and their customers more information about what's going on inside the magic box.
This paper presents a new approach to repair industrial gears by showing a case study where pressure angle modification is also considered, differently from the past repairing procedures that dealt only with the modification of the profile shift
coefficient. A computer program has been developed to automatically determine the repair alternatives under two goals: minimize the stock removal or maximize gear tooth strength.
