CASTING INNOVATIONS Powerful Features Simplify Computed Tomography X-ray


To keep pace with the chang- ing demands of X-ray inspection users, a new X-ray system from YXLON (Hudson, Ohio) includes features that meet current needs and anticipate challenges. The YX- LON FF35 CT X-ray System was designed with both the novice and the seasoned X-ray system operator in mind. The FF Series introduces a new intuitive user interface along with many other features that were on YXLON’s customer wish list. The system has both a single- and dual-tube configuration, which allows for a variety of sample sizes. Other features include software developed for metrology needs, such as dimensional and internal struc- ture measurement, ease of transi- tion from 2-D to 3-D inspection, reduced probe set-up time, easier part manipulation through touch screens, remote monitoring, and push messaging.


Te FF35 CT with a single-tube or dual-tube configuration offers ver- satility with high-resolution and pre- cision, and a broader range of inspec- tion, including the measurement of numerous components and different materials. Te single tube configura- tion works well for small castings, 3-D printed parts and assemblies. Te high-resolution image quality al- lows users to accurately detect defects and discriminate between blowholes and material. Sharp contrast makes exact measurements possible. Customers also indicated a desire


for greater heat reduction within the system. To achieve this, all tubes used in the FF CT Series systems are water-cooled. Temperature optimization is realized not only at the target (the small piece of metal where X-ray is generated by accelerated electrons), but also with the heat-generating internal compo- nents like magnet coils, which are needed to focus the electron beam. This allows a quick temperature


balance, essential for a stable posi- tion of the focal spot and a stable operation that limits additional thermal expansion of the tube. Ad-


The YXLON FF35 CT can be used to detect the porosity and metrology of internal structures, such as for this aluminum cast part.

ditionally, a granite manipulator base maximizes precision. Another customer-requested


feature was remote monitoring: this eliminates the need for the operator to be in front of the system during the entire inspection time. YXLON designed remote moni-


toring software, which can be run on 64-bit Windows PCs or tablets. Te software window can be minimized to allow operators to multitask. Tey can check to see if the CT scan is still running or if the results are already available, all without having to return to the system. Other features of the FF CT


Series include the IntelliGuard feature, which can determine the outer shape of an inspection part


during a typical 360-degree CT scan rotation in 30 seconds. This permits the systems to recognize how close the object can travel to the detector or tube to avoid collision. Another feature is FlexCenter, which allows users to define a rotational axis. He- liExtend, a helical CT feature, can eliminate artifacts in long parts that have a small diameter. With IntelliGuard, part manipu-


lation in a CT system is simple. A system health monitor displays a red, yellow or green light to indicate the overall status of system components at a glance. This feature is also avail- able remotely.
