CASTING INNOVATIONS


• Automotive & aerospace: Al- lows engineers to do virtual testing of machinery, helps understand failures, and works as a research & development tool to analyze structure and simulate reactions.


A wide range of industrial scanning


equipment styles and sizes are avail- able to suit different types of applica- tions. Micro units in table top styles for lab use up to full industrial grade floor models for in-plant or in-pro- cess use to portable measuring arms that can be used on the shop floor or out in the field are all available today, usually from a manufacturer or a service organization, for one-time contract use, with rent or lease-to-buy arrangements optional. Typical CT scanners offer a wide


range of measurement capabilities and features. Sizes start with small desktop models which meet the most


Metalcasters can use this technology to check for air bubbles and overall porosity.


stringent demands and measure the smallest 3-D detail from 0.25µm. Tey can be equipped with differ- ent X-ray powers, from 160kV for nanometer resolution through 225 kV, 320 Watts to the highest power of 300 kV, 320 Watts. Larger scanners are avail-


able for extremely fast CT data acquisition on workpieces up to 19.7 in. (500 mm) diameter and 23.6 in. (600 mm) in height, weighing up to 110 lbs. (50 kg).


Typical functions performed on this type of system might include 3-D analysis of a scanned turbine blade, automatic pour porosity volume analysis on an aluminum casting and 3-D measurements with nominal-actual CAD com- parisons on a machined aluminum cylinder head. The future of industrial scan- ning holds unlimited possibilities, especially when combined with 3-D printing or other additive manufacturing methods. As im- provements are made in technol- ogy and performance and costs continue to decrease, the industri- al scanning industry is preparing for growth.
