Gear Metrology. Requesting help in processing raw XYZ, PLY or STL data from a point cloud files in order to obtain gear geometry in the form of a gear report.

I have measured gears via the optical focus variation method with a confocal microscope, and I have collected point clouds. I can provide the data in either STL, PLY or simple XYZ coordinates (as well as a drawing and possible CAD model). Normally, on a coordinate measuring machine (CMM) the gear report would be created automatically from the collected XYX coordinates via standard gear software. Gear software is not available for the microscope, so I am hoping that this can be done in Matlab. I am now looking for someone who has knowledge or experience in creating a gear report from raw data. I am a basic MATLAB user, but I believe that this should be possible (can anyone advise please?).

Hi Denis,

MATLAB offers several functions for reading and preprocessing 3D data. To assist community members in providing better support, it would be beneficial if you could share a sample data file along with the expected format of the gear report.

Thanks

Thank you so much. The files are quite large so I attach a link. Data for MATLAB
