Roundness / Circularity Measurement

This is a measuring device that can non-contact measure surface shapes such as concavities, undulations, and surface roughness. We will introduce "heating deformation observation" using a 3D shape measuring machine. First, we acquire a 3D texture image at room temperature, and then we acquire a 3D texture image in the heated state. By overlaying the texture images before and after heating and checking the differential texture image and cross-sectional profile, it can be seen that the substrate in the heated state has higher ends and a lower center compared to the room temperature state.

Are you having trouble evaluating whether the axes and the shaped holes are according to the design specifications? We attach samples to the KEYENCE "VR-6200" electric rotating unit and obtain 3D data by rotating it 360 degrees, measuring roundness from the profile. Additionally, we measure circularity using the image processing software "WinROOF2021." For more details, please refer to related products and catalogs. 【Features】 <Roundness Measurement Using VR-6200> ■ Attach the sample to the electric rotating unit and rotate it 360 degrees ■ Obtain 3D data and measure from the profile <Circularity Measurement Using Image Processing Software> ■ Using WinROOF2021, we measured the circularity of commercially available probe pins, and it was observed in the SEM image that they were not perfectly circular.
