[La...] Posted August 28, 2018 Share Posted August 28, 2018 I am having problems checking small chamfers, like in the .5MM and smaller range. Open to any suggestions. Thank you to all in advance!!!!

[00...] Posted August 28, 2018 Share Posted August 28, 2018 What machine are you using? What size stylus are you using? How are you currently trying to measure them?

[Je...] Posted August 28, 2018 Share Posted August 28, 2018 Try a helical scan starting a the bottom and working up. 3 - 4 rotations should be sufficient.

[Ca...] Posted August 28, 2018 Share Posted August 28, 2018 Checking chamfers with circular or helical paths? Do you mean 0.5mm fillets? Link to comment https://qualityforum.zeiss.com/topic/18352-checking-small-chamfers/#findComment-103204 Share on other sites More sharing options...
[Er...] Posted August 28, 2018 Share Posted August 28, 2018 Single points works best for me on really small cone shaped stuff. For example two cricle paths with 8 points each, rotated 22,5 deg apart. If its cone shaped? 😮 Link to comment https://qualityforum.zeiss.com/topic/18352-checking-small-chamfers/#findComment-103206 Share on other sites More sharing options...

[Ma...] Posted June 25, 2019 Share Posted June 25, 2019 Please sign in to view this quote. Ian, as far as course filtering and fine filtering, exactly what filters are being used? are you using 3 for a factor for outlier for inside the workpiece and outside the part? are you using only outliers for the Range of Data Reduction? Or are you Including Adjacent points? if so, how many? or are you using the "to computed feature" option? Are you using any specific number of iterations? Also what are you using for a wavelength Lc, for both rough, and fine? I have been programming for a while now and as far as filters being used, I rarely use them unless ABSOLUTLEY necessary, and reason for that is because I feel like I have a problem understanding them. However, I have a chamfer I have to measure right now that is a typical 45° chamfer, however it is only .005, +.005/-.000, and I am having problems measuring it using the method you posted and I think it is because I am using the wrong filters. Also, did I understand what Kai wrote correctly, we measure the chamfer two separate times?
