You can make section with a cylinder, so you can have correct line. But my knowledge about gears is nonexistent. You can create a helix curve ( in Curves menu ), but i don't know how to report that. I know how helix looks like and how to calculate it, but not for gears - thread is some sort helix too. I once tried on cnc mill to calculate helix path according to datasheet of mill tool. I ended in distance of circumference over angle.

Alright guys, I feel like I should be able to get this easy but I'm struggling. Still learning the software. How can I get this helix angle on this gear? I've made a line on the gear tooth, and I want the angle back to either the ID or the top plane which is shown.

Hi Jorge, The qualification modes available depend on the probe sensor type you have selected at Extras > Settings > CMM > Probe. From the CALYPSO online help: "Qualify passive stylus - This is the only possibility to qualify the stylus geometry for passive measuring probes." If Tensor mode is being displayed instead of Passive, it sounds like an active sensor type may be selected rather than a passive probe. I would recommend checking the probe sensor configuration in the location above and verifying that the correct type is selected.

@Marcel Hartmann I have a question for similar thing. In older Calypso i used to plot a curve in 3D and i could make pins with deviations. Now on newer Calypso i can not make pins directly from top view - once i can see deviations on sides- those can be pinned, but i could not trigger ones in view vector. Once i changed plot into coloured i can pin any point.

I'm using Calypso 8.0 and when qualifying master probe show tensor mode insteoff passive, any idea how to change

Hello Mads, Thank you for providing confirmation that the issue has been resolved in the latest service pack/patch.

Hi Carlos, it should fix your problem, the error should only appear within inspections that have the following activated: On the Zeiss Portal ( ZEISS Portal ) you can only get the latest ServicePack 8.0.16! But its also fixed in that version. Best Regards Marcel

Theoretically this profile has to be within tolerance with it's max deviations from both sides. Like form Deviations can be from -0.025 to +0.125 to fulfill both conditions - their distance is within 0.15 ( +- 0.075 from center curve ) and within 0.25 ( +- 0.125 from nominal curve )

I got almost no clue about gears 🙂 The best part about the generator approach is, that the parameters it askes for, tell you what you need to measure aswell.

The gear generator is a good idea. I'll be GOM scanning the gear as well. Should be able to figure out Helix angle from that. Just want to hear from people who have experience doing this, it might save me some time.

Hello Chad, i would probably look for a gear generator and put in parameters i measured at the sample. Then at some point start checking by surface comparision how close i am getting.

Hi All, How do you pull the sub-values from a true position characteristic with PCM? I have a true position of a Ø (-H-) to a datum scheme (-A-B-C-), and it reports the calculated value. I need to report the correction values for pulling the true position in spec. I know that you can enable an additional printout to get these values, but I would prefer to pull this into a standalone characteristic (Result element) using PCM. When I attempt to cheat the software with "getActual("-H- Position1").y" I receive the following error. Any help is appreciated!

Hey Marcel I'm on 8.0.12. Would updating to 8.0.1202 fix this? I just find it odd how it's only happening on these specific programs.

Can anyone give me tips for reverse engineering a 52 tooth helical gear? I'm not finding much on this topic when I search old threads.

Appreciate the response! I did end up figuring it out. I had "additional printout" enabled. This adds additional data on the excel report, but doesn't add it to the custom printout template we are using. Instead, it just leaves a blank for some reason. Turning additional printout off removes these blanks.

No, we've never used that feature and I did double check that it was still off early in my checks.

Hello Carlos, which CALYPSO Version exactly are you running? I found a BUG with this exact Error description, but it should have been solved with CALYPSO >=8.0.1202. It was caused by an Point List export from a Cone. Atleast your Error mentions the "piWebPointListResult" so it could be the exact same issue. Best Regards Marcel

I am still wrapping my head around dynamic profile and how to report it, I have not had time to test the theory. Hearing if this works or not will be interesting to say the least.

The following creates a file name that will never overwrite. It appends a Date and Time to each file name. "<Some Drive letter>:\CMM Data Files\Table Files"+"\"+getRecordHead("drawingno")+"\"+getRecordHead("order")+"\"+getRecordHead("dmesn")+"\"+getRecordHead("planid")+"_"+getRecordHead("partnbinc")+"_"+getRecordHead("date")+"_"+getRecordHead("time")+"_"+"hdr.txt" The above also nests data in a set of Folders for traceability. drawingno = Part Number order = Our Job Number dmesn = CMM the part was run on partnbinc = Part Counter (We use this as a counter and or Serial Number) date = Current Date at time of file creation time = Current time at file creation Example file name: <Some Part Number>_B_Targetting_RDS_05-11-20261_SC-028_2026-8-31_2_05_36 PM_.pdf Program Name Serial Number or Part Counter Creation Date Actual Time (2:05:36 PM)

I plan on testing this, just need to find time to do it.

Full form thread milling can aid in this issue. You will have to use the Pitch Diamter tolerances for the feature tolerance to be correct when applying modifiers. I have been using this method for nearly two decades. On a side note, I have worked with many companies from smallest to the largest who have allowed using minor diameters to control the true position tolerance and location.

In the context of dynamic profile, could we calculate the difference of the size of the feature and add or subtract from the tolerance with PCM?

Hi all, I'm getting this System Error message and am not really sure what it means. This is the first time it's popped up, although I double checked the opposite hand program which uses the same model and got the same error when I tried to generate the report from the previous run. The only thing that's changed since the last time we ran these programs is that we were using Calypso2023 and are now on 2025. Doesn't seem to happen with any other program. Thanks in advance

Ich hoffe ich hab das Problem richtig verstanden: Der Trick ist, dass man durchaus mehrere Elemente in einer Datumzeile einfügen kann. Anschließend noch sicherstellen, dass sowohl [Pl] und [SL] ausgewählt sind, dann hat man einen Bezug ohne verbleibende Freiheitsgrade.

For that CZ of 4x holes. Make group of elements then place TP on that group. I hope your version is having this - i got 2025 and it's there
