[SH...] Posted June 16, 2022 Share Posted June 16, 2022 It is compulsory?, that while programme with rotary table I should use rotary table to measure the base alignment features. Link to comment Share on other sites More sharing options...
[Ri...] Posted June 16, 2022 Share Posted June 16, 2022 If you are going to use the RT, you have to have an RT Alignment. There are three methods for doing this. 1) With features on the part itself - probably the best way, but most time consuming as you are performing an RT alignment every run 2) The cylinder method - really solid choice, I would just ensure that the length of the cylinder represents your tallest part 3) The double sphere method - another solid choice, and I believe this is the method that Zeiss uses to calibrate the RT. I would just ensure that the distance between the two spheres represents your tallest part. Link to comment Share on other sites More sharing options...
[SH...] Posted June 17, 2022 Author Share Posted June 17, 2022 Please sign in to view this quote. Thanks for the detail explanation and I would go with the first method. But while measuring the base element features should I rotating the part or I just move the probe around the feature without using RT that is my confusion.. I read somewhere that don't use RT for base assignment and my seniors telling should use RT for base Alignment and so it's confusing me. Link to comment Share on other sites More sharing options...
[Ow...] Posted June 17, 2022 Share Posted June 17, 2022 If you are using the part to set up the rotary table axis where you measure with the table set at zero degrees and then rotate and measure 180 degrees, you MUST have the “Base Alignment rotating with RT” option turned OFF on the features used set the rotary axis, everything else will be set to “on” rotate with base alignment. If you are using either one of the sphere methods to set up the rotary axis (short parts are OK using the one sphere method, tall parts you would want to use the two sphere method), it doesn’t matter how you measure the base alignment as long as you have the “Base Alignment rotating with RT” option turned ON, which by default, always is.

[Cl...] Posted June 17, 2022 Share Posted June 17, 2022 We have one O-inspect w/rotary dedicated to a cylindrical part. I use the part to create the RT alignment. I measure two cylinders on the part (measure one, rotate 180°, measure the second) and create a symmetry from them. I use the symmetry for the RT alignment. This helps compensate for any potential run-out of the part. Link to comment Share on other sites More sharing options...
