[Jo...] Posted May 27 Share Posted May 27 Hi All, Can anyone tell me how to program a total runout on a gear surface? What kind of feature should I use to get the best result and how should I evaluate it? Please see image from actual drawing. Thanks in advance! -Joe Barajas Link to comment Share on other sites More sharing options...
[Ch...] Posted May 27 Share Posted May 27 (edited) would be easier with Gear Pro, can also be done in Calypso. Do you have Gear Pro ? method for Calypso to align gear : https://qualityforum.zeiss.com/migration/images/2500_fcdfcff2533342bd8f5c17a3d8f6a9b5.pptx Edited May 27 3 Link to comment Share on other sites More sharing options...
[Jo...] Posted May 28 Author Share Posted May 28 Please sign in to view this quote. Hi Chris, I don't believe I have Gear Pro. Is that part of the standard package, or is it a separate license? If it's a separate license, then I definitely don't have it. Link to comment Share on other sites More sharing options...
[No...] Posted May 28 Share Posted May 28 It's not just a seperate license, it's a seperate program. 1 Link to comment Share on other sites More sharing options...
[Ch...] Posted May 28 Share Posted May 28 can be done without it just follow .ppt in link, make sure where you do your gear gap 'find' alignment, you also check tip dia at that height, otherwise on a helical gear, obviously you would end up falling off. give it a try, I've done it dozens of times in Calypso only works fine. 1 Link to comment Share on other sites More sharing options...

[Ch...] Posted May 28 Share Posted May 28 if you have the cad model it helps, from your gear 'GAP' alignment, rotate 1/2 gear pitch, since yours appears to have 13 teeth, rotate 13.846° from the gap alignment at the same Z height as gap alignment. Program a point with proper vector (easier from CAD - also your CAD should have a gap or tooth aligned with X or Y). Rotational Pattern the point 13x , angle = 27.692° (360/13) . Recall points in to circle - report runout. If you don't have rotary table suggest coming straight down with down probe. With the pattern, it should take care of clearance planes. Good luck ! 1 Link to comment Share on other sites More sharing options...

[Ch...] Posted May 29 Share Posted May 29 Richard is correct, for total runout the entire OD surface should be included, and I have done this, but thought it might be a bit much for you. I think there are a few ways to get the helical paths on the teeth, since he is showing a cylinder probably a helix path strategy. A more common simpler approach might be to check top middle bottom of the OD. Keep in mind for this, due to it being a helical gear, you will either need to calculate the twist offset alignment, which is possible, but for a beginner I just suggest finding the gap in 3 places, top, middle, bottom. Good luck ! 1 Link to comment Share on other sites More sharing options...
[Ch...] Posted May 29 Share Posted May 29 For a helical strategy I think it would be best to have the CAD aligned (e.g. gap aligned to X or Y), so you can make sure all traces will be on tooth tips, etc. Let us know how you make out ! 1 Link to comment Share on other sites More sharing options...
