A study was conducted to isolate the influence of pre--rough machine processing on final dimensional
distortion. Methods are discussed to aid process development and minimize dimensional change during
carburizing. The study examined the distortion during carburizing between five possible raw material starting
conditions. Coupons were used and manufactured from each population ofmaterial processing. All coupons
were carburized and hardened at the same time. Dimensions were made before and after carburizing using a
scanning coordinatemeasurement machine. The results show that dimensional distortion during carburizing
increases with mechanical and thermal processing.
