All new products will be designed in a digital product environment, where individual parts can be included in assembly models to review form, fit, and function. New designs often include more complex shapes that only the investment casting process can create. The new challenge that faces our industry is how in inspect parts that are created strictly from a 3D model. The days of scribe lines and height gages are long gone. New inspection equipment and software are available, however the lack of broad use across our industry has failed to define industry standards for inspection technique, equipment, and software. This paper outlines the equipment, software, technique, and data analysis tools used for noncontact inspection at O’Fallon Casting. Additionally I will address some situations that occur during data acquisition, data processing, and reporting. These items include: what is acceptable when correcting a surface for comparison to the 3D model, how to obtain data without best fitting scan passes of the laser, and proper methods of aligning data to the 3D model. The conclusion will focus on the time advantages of laser scanning versus touch probe inspection of every feature defined in the part drawing, advantages and disadvantages of defining feature size and location with model based inspection.
