This dataset is part of a series showing the surface of an agate stone at each stage of polishing. This is the stone’s surface after tumbling with 125-grit silicon carbide. The low area is an inclusion of a softer material in the stone. Measured with a Zygo ZeGage Plus, 10x objective, desampled. Data source: Bob … Read more
This dataset is part of a series showing the surface of an agate stone at each stage of polishing. This is the stone’s surface after tumbling with 500 grit aluminum oxide plus plastic pellets. The low area is an inclusion of a softer material in the stone. Measured with a Zygo ZeGage Plus, 10x objective, … Read more
This dataset is part of a series showing the surface of an agate stone at each stage of polishing. This is the stone’s surface after final polishing at 1500 grit. The low area is an inclusion of a softer material in the stone. Measured with a Zygo ZeGage Plus, 10x objective, desampled. Data source: Bob … Read more
This dataset, showing the scales of an orange throated darter, was featured in our blog post, “Surface roughness sheds light on how fish evolve.” It’s a great dataset to try out the Path/Curve Cross-Section tool in OmniSurf3D. Use the tool’s handles to draw a curve along one of the scales. The profile along that curve … Read more
A chipped tool with photo overlay. The photo overlay is useful to visually assess the damaged region. This data demonstrates the power of OmniSurf3D’s profile wear analysis tool and its “corner” reference geometry. Measured via Alicona SL.
This dataset is part of the Microfinish Comparator series. A comparator can be used to qualitatively gage surface finish, by comparing it to a sample visually or by touch. This is the 500ST shape turned sample. The GAR S-22 microfinish comparator gage used for this series. Measured via Zygo ZeGage Plus (10x) Data source: Digital … Read more
