Abstract:  
ABSTRACT In common manufacturing process of automotive gears, shot peening is set up between hardening process and final grinding process. As the purpose of shot peening is surface modification, the machine is commonly found in the same area with heat treatment equipments.In recent years, particularly in some production line for small size gears for automotive transmission, the peening machine is often installed at the first process of machining line right after the heat treatment. In other words, the location of machine is changed from heat treatment plant to machine shop. Due to this trend, the installation space allocated to the peening machine is getting tighter. In response to this demand, the construction of shot peening machine of compact shape to fit to the machining line and the method of controlling various elements related to the peening intensity in actual machine are introduced in this paper.
