Calculating centre of gravity will be acid test. I think the attachment can help you.

[Ri...] Posted January 11, 2021 Author Share Posted January 11, 2021 I've seen the formula, but I'm most intrigued in what devices people are using to get the information for the equation.

Oh, all your probes weigh 20lbs 🤣 I stay fairly elementary with it, I weigh the left and right probe and no matter the length of each, make each side weigh about the same.

[Ri...] Posted January 11, 2021 Author Share Posted January 11, 2021 Sometimes that can work, but in the case of really long stylus systems that might not be feasible. You can manipulate the balance depending on the length/weight of the fulcrum.

[Cl...] Posted January 12, 2021 Share Posted January 12, 2021 Just one stylus configuration I built for one specific part years ago. Looks like it would be a problem, balance and weight wise, but wasn't.

The mass of each component can be found either in the shop or in Stylus System Creator. For some components I have to guesstimate where the center of mass is located but its is not rocket science. You will not miss Saturn by 2000 miles because of a small calculation error here on Earth. 0.1 Nm is quite much and I'm pretty sure that the sensor can cope with a lot more than that without loosing to much accuracy. The biggest problem is the stylus system falling out of the sensor when picking it up from the holder. A bad balance might wear the sensor faster than normal though.Tilt torque.pdf Link to comment https://qualityforum.zeiss.com/topic/13262-torque-balance-specification/#findComment-67364 Share on other sites More sharing options...

Got lucky that it didn't ruin the head, but Zeiss had to come in and tune the head because I was getting tarration errors. It was due to the unbalance. Have a stylus system unbalanced is OK for very minimal usage, but long-term it is detrimental to the probe head.

[Ro...] Posted January 13, 2021 Share Posted January 13, 2021 Long time ago, in a job far far removed...... I was told buy the guy who taught me lots of cmm things that if the stulus system should stand upright on a table. If i had a long or heavy styli on 1 side i need to add something to the other side to bring it back in balance. I don't know if its true, but it made sense to me so i stuck with that rule going forward. but to be honest it's pretty easy to sway my thoughts, when I was a kid I was told (by another kid) that if you stared at a dog while he's going #2 that it'll make you go blind. It made sense to me, so for my whole life i always look away. And i actually think my life is better for that.

Even though it isn't technically true, you live a much better life if you don't spend it staring at dog's buttholes.
