[Ia...] Posted February 3, 2020 Share Posted February 3, 2020 Hi, My engineers want a very high resolution for a curve trace of a gear. Step width of 0.0015" or smaller. When I ask for a step width of 0.0015" it will only produce 1854 points which is approximately 0.015" Also when I export the points, it will only export 1854 points. Is there a way I can get a higher resolution than this? Link to comment https://qualityforum.zeiss.com/topic/16602-high-resolution-in-curve/ Share on other sites More sharing options...
[Ch...] Posted February 3, 2020 Share Posted February 3, 2020 Try creating your curve with the desired number of 'nominal' points. As opposed to creating your curve then increasing the amount of points in the features.

[Cl...] Posted February 3, 2020 Share Posted February 3, 2020 Maybe someone else can clarify this, but isn't the 1854 number the nominal amount of points? Multiply 1854 x3 and use that amount.

[Ia...] Posted February 3, 2020 Author Share Posted February 3, 2020 This is what I'm getting. Does that look right? I have never seen the blue and red arrows before.

[Ch...] Posted February 3, 2020 Share Posted February 3, 2020 I get the red and blue arrows from time to time. I don't know what they mean but I probably should.

[Ia...] Posted February 3, 2020 Author Share Posted February 3, 2020 Thanks Guys. I'll give this a try. If the results are based on the actual points, why is it reporting on the same number of points as the nominal amount?

[Ri...] Posted February 4, 2020 Share Posted February 4, 2020 As an FYI I recall with Curve and or Free Form having a calculation issue on surfaces with more than 20,000 points. I cant remember the entire post I read, it may even be on the old forum.

[Ri...] Posted February 5, 2020 Share Posted February 5, 2020 Please sign in to view this quote. It will work, but it could take it a while - especially if you are doing any kind of best fit. I had a Free-Form that had close to 100k points that took 8 hours to perform a best-fit (it's all in the accuracy setting).

Change to points cloud it takes less than 1 minute with 2 million points Link to comment https://qualityforum.zeiss.com/topic/16602-high-resolution-in-curve/#findComment-92608 Share on other sites More sharing options...
[Ri...] Posted February 6, 2020 Share Posted February 6, 2020 I didn't think you could give a Profile measurement though with the Point Cloud? I know that 2019 has made some improvements. In addition, the Profile required a Best-Fit in a few axis, and then I had to use that new Best-Fit alignment to calculate some Positions. I don't believe there is any way around that.

[Ke...] Posted February 6, 2020 Share Posted February 6, 2020 Side Note: I would be grateful for anyone who can provide documentation of best uses for Point Cloud, that does not involve optical of laser scanning Link to comment https://qualityforum.zeiss.com/topic/16602-high-resolution-in-curve/#findComment-92612 Share on other sites More sharing options...
[Ri...] Posted February 6, 2020 Share Posted February 6, 2020 Please sign in to view this quote. I don't know about documentation, but I use them mainly for when a customer wants a raw points in a text file. Like Israel stated, it can handle a massive amount of points with little to no lag.
