Femoral Hip Inspection

Below are two graphical based reports of Femoral Hip Implants. One is in a region where there is no coating and the other is in a region where there is a rough coating applied to the implant. We have no trouble going between coated and uncoated regions. Also, we can handle shiny parts as well as dull parts.

Parts are scanned around a whole 360 degree viewpoint. Normally, about 250,000 to 750,000 points are gathered in a matter of about 20 seconds to a few minutes, depending on the properties of the surface. These are then coupled with the part CAD file and/or CAD cross sections to automatically extract cross sections from the scan and compare to the CAD model. Tolerances permit bands to be drawn. Each extracted point is then compared to the nominal (CAD) line and deviations reported.

These cross sections are shown graphically divided into octants labelled 1 to 8, and in each octant a bold line shows the deviation for the furthest point in that octant from the nominal. Each cross section is then analyzed for the width and height on the diagram. This is especially useful for coating thickness measurements. At the bottom of the page are shown the maximum deviations for each octant in inches and in mm. Note that the scales on the left and bottom are in mm and for the top and right are in 1/10″ increments. Finally, a complete report is prepared in text file format for easy import into user programs or into applications such as Microsoft Excel.
