[Ro...] Posted June 15, 2018 Share Posted June 15, 2018 Does anyone use this? Looking for Lobbing effect from Grinding on a tight tolerance journal +/-.008mm I am using a 3mm Ball on a 40.2mm journal. running 7.5mm for a speed and a point at 0.100 There are a few different evaluation frequency and I will be totally honest I am not 100% sure what I am looking at and what the charts that are printing out. I appreciate any information. Link to comment Share on other sites More sharing options...

[Ro...] Posted June 22, 2018 Author Share Posted June 22, 2018 No, this is more internal for grinding Machines, to analyze what is going on with the Grinding wheels. Link to comment Share on other sites More sharing options...
[Me...] Posted June 22, 2018 Share Posted June 22, 2018 Can you use Roundness Plot? Link to comment Share on other sites More sharing options...
[Jo...] Posted June 22, 2018 Share Posted June 22, 2018 If you only look at wave forms between 1 and say, 10 UPR, then that will generally identify work holding distortion. Filtering somewhere from 50-500 UPR will show things like tool or grinding chatter. The plot will be nice and round but the small undulations will be visible. I think Calypso defaults to 1-50 UPR if you don't change anything. Link to comment Share on other sites More sharing options...
