[SH...] Posted January 19, 2021 Share Posted January 19, 2021 I got a new cylindrical probe today for checking sheet metal job, can I add cylindrical probe to my automatic probe qualification program?. How can I qualify the ball at the end?, I mean z axis reference. Link to comment https://qualityforum.zeiss.com/topic/6616-cylindrical-probe/ Share on other sites More sharing options...
[Ri...] Posted January 19, 2021 Share Posted January 19, 2021 If it is spherical bottom cylinder stylus, it gets qualified the same way as other spherical balls.

[SH...] Posted January 19, 2021 Author Share Posted January 19, 2021 Yes, it has hemisphere at bottom. But calypso manuals says measure two circle at RS equator and a manual point at top of RS. In work's in manual mode, no cnc?? Link to comment https://qualityforum.zeiss.com/topic/6616-cylindrical-probe/#findComment-26450 Share on other sites More sharing options...

[Ro...] Posted January 19, 2021 Share Posted January 19, 2021 One of the things that PCD does very well, and Calypso struggles at. In PCD you can use the ball end cylinder probe just as any other probe, but in Calypso its only a cylinder. Additionally the "Length" of the styli will change every time you do a manual alignment, so if someone on the off shift breaks a cylinder probe and manually takes hits, your whole program can get screwed up.

There is no difference in the qualification, and usage. Link to comment https://qualityforum.zeiss.com/topic/6616-cylindrical-probe/#findComment-26456 Share on other sites More sharing options...
[Ri...] Posted January 19, 2021 Share Posted January 19, 2021 Here is a video of it being qualified to show proof. https://vimeo.com/502320068/3a4984d055 Sorry for the shake...

I think you would quality the bottom hemisphere as one stylus (position #1), and the shaft as a second stylus as the cylinder in position #6. I did this with one of my probes, also for a rather thin 'sheet metal' type part. Just make sure you keep the 'bottom' of the cylinder above the radius.

You just have to move the location as to where you want it measured. I have done this numerous time for capturing edges. It works well, and the spherical bottom allows you to properly qualify it.

[To...] Posted January 20, 2021 Share Posted January 20, 2021 I think what Roberto is referring to is the issue with how parallel the sides of the cylinder to the Z axis? I would think that after you qualified the radiused end of the cylinder probe, I might create a program that measures the reference sphere further up the cylinder to see what the variation is. In other words, pick a spot on the cylinder that you want to use when measuring your parts and validate the X, Y and Radius values to suit.

[Ri...] Posted January 20, 2021 Share Posted January 20, 2021 I understand that point of view. That's why I say to not use cylinder probes because you have no guarantee that where you are measuring on the probe is properly qualified. This is because no matter what the cylinder probe isn't truly perpendicular to the workpiece - the issue is even worse on the XXT.

I realize this is an old post but hopefully you guys could answer another couple questions: if Calypso calls the geometry a sphere and you qualify another position (#6), how do you do that exactly? When qualifying you have to probe in the direction of the shaft, so if you qualify it as position #6 then how do you probe the qualification sphere with the "side", so-to-speak, of the cylinder?
