[ad...] Posted September 24, 2020 Share Posted September 24, 2020 A general question here Running a Poly line along a 0.40ra face, what speed would you use for accuracy and speed? I am getting the same results pretty much running at 10% & 100%. but our programs are all are set at 7%. Any advice? Link to comment Share on other sites More sharing options...

I think it depends upon the machine my machine is contura G2 and I was advised to have a 15mm per second speed for scanning. You can have 100% speed. You have to control your scanning speed inside strategy window. Your 7% speed really drives me nuts.... Link to comment Share on other sites More sharing options...
[Ma...] Posted September 24, 2020 Share Posted September 24, 2020 Where are you get those precentages? We have full speed on remote control, but scanning speeds varies from 3mm to 15mm. If i speed up, then i increase measuring force. But on our Vast XT we use 200mN Link to comment Share on other sites More sharing options...
[ad...] Posted September 24, 2020 Author Share Posted September 24, 2020 The operator explained it to me as a percentage! 😮 We are using your same set up on a Navigator Prismo, will keep this in mind.

Or just staying there with changing it all the time? Measuring plans should be running always the same for all time without user intervention.

[Ro...] Posted September 25, 2020 Share Posted September 25, 2020 A lot of it will depend on your head. I'm not familiar with the prizmo, i've only programmed Conturas, but i know that programs that i use on my XT head run great for me here, but when sent to an XXT machine have lots of problems with "Air Scanning" and lifting from the surface at seemingly low speeds. I run most of my scan speeds at .3 to .4 inch (7.5-10mm) depending on the surface, which is pretty fast on these fairly small parts, but the speeds are cut in half with the XXT. Either way, i would think that 7% of whatever speed programmed is really really really slow. Link to comment Share on other sites More sharing options...
[Ow...] Posted September 25, 2020 Share Posted September 25, 2020 If you're getting the same result and using the same probe and the surface finish never changes, 100% should be fine on an XT vast type of active scanning head but, like Roberto mentioned, the XXT passive scanning head is a completely different animal. You might do a repeatability Gage R&R test on several parts to make sure because just because it does it once doesn't mean it will do it every time in some scenarios, especially if the geometry of the surface being scanned has a lot of changes in shape. Probe shaft/ruby size, rigidity and especially length of probe play an important role in canceling out noise and getting good repeatable speed .
