This dataset is high on our “coolness scale.” It’s nearly 250 mm in width—quite a bit larger than our typical surface roughness measurements. It does an excellent job of showing how longer-wavelength waviness and form can be analyzed. There are some small areas of bad data which can be repaired with the OmniSurf3D Surface Editor … Read more
You may recognize this image from our blog post (Image Overlays in OmniSurf3D) showing how image overlays can provide a more realistic sense of a surface. The .os3d file format can include an image overlay file within it. In OmniSurf3D click the camera toolbar icon to toggle the image overlay on or off (the button … Read more
This data is representative of a range of parts with a conical overall shape (valve seats, as an example). When dealing with data such as this it’s important to turn off data filling (Analysis Setting > Missing Data Filling > None) to avoid bridging the empty inner and outer areas. If you remove the cone … Read more
In our blog post, Comparing Apples and Oranges, we talk about how a properly scaled profile graph can give great insight into surface features—while an improperly scaled image can have you chasing non-existent process problems. This data of an orange, combined with the data of apple skin, can help show the effects of vertical scale when … Read more
In our blog post, Comparing Apples and Oranges, we talk about how a properly scaled profile graph can give great insight into surface features—while an improperly scaled image can have you chasing non-existent process problems. This data of an apple, combined with the data from an orange peel, can help show the effects of vertical scale … Read more
This segment of the edge of a 2 Euro coin includes an interesting star shape embedded in the edge of the coin. Try removing cylindrical form (Analysis Settings > Geometry/Form) and displaying the Wavelength Content graph to reveal the periodic pattern. Measured with a Zygo ZeGage Plus, 10x objective (desampled). Data source: Digital Metrology … Read more
