fast probing mode

[[Ba...]]

Does anyone use the fast probing mode.
my probe is vast XT gold.
I tried it, after I ticked the checkbox,
when it check the pitch, the stylus probe the teeth surface very light and quickly without waiting which very like the TP200 probe, and without "beep" sound. not as usual that the stylus contact with the surface and wait about 1 second, then get the point with "beep" sound.
How much probe force does the fast probing mode use ? can anyone introduce how it works?

I don't know the exact math/science on how it works, but typically it will pre-measure the tooth/gap thickness on the first tooth, set that to 0 for the rest of the teeth, and then based on the immersion depth that you have set it will go around and measure the surfaces without pre-loading the stylus.

I typically don't suggest it to people unless they have a lot of teeth, and they are trying to shave cycle time. If you are looking for accuracy, I wouldn't use it.

I've had issues with it in where if there is a lot of runout, and variation in the tooth thickness where it won't work.

Having said that, I tend to not suggest single-point pitch measurements. I have always had more success using the double-flank measurement. It is technically faster as you only take one point instead of two. 🙂

I've experimented with it, hoping to get indexing speed like a gear analyzer (Gleason M&M, etc.). However, I got poor pitch results. Would not recommend it.

A lot of it has to do with the part that you are measuring. If it's a poorly made part, you are going to get poor results.

Gleason uses a different type of probing system, so the behavior is completely different.

I would not recommend using a gear checker either way because you are not measuring the datum structure and using that as your alignment. I know that some of them have options to measure a circle on the ID, and a plane on the face, but the results are never what they should be.

Where to go to turn this ON? Is this inside Calypso? thanks

Idk about this application, but in the hexagon world It is influenced by touch speed, approach distance, acceleration parameters etc. It is a time/speed relationship and triggers one direction. Normal behavior is to take several triggers approach/retract and better account for deflection.
