The part is about 7″ by 10″ and approximately 3″ thick. It was a challenge to machine because the wall is only 0.200″ thick and required special measures to keep vibration and distortion under control. Over 30 programs were needed to run the part and the total runtime and programming time was almost 40 hours. The material is Alumec 89 aluminum. The raw block weighed almost 25 lb (11.5 kg) and the finished part is 14 oz (390g).
