Figured I would ask on here before I call up Hexagon and ask for assistance. So This new company I'm working with has bought a brand new off the shelf 7-10-7 global EPS (aka, Brown&Sharpe) top speed parameters shows 300. This thing is slower at top speed then this old Mistral, I used to run. I would think this thing should go a lot faster. At one facility here, I have a 5-7-5 global EPS top speed 500. I would like to believe that this thing should move, so before I go changing any numbers. I would like to know if this is the best this thing can do or is there a setting that can make this thing move. Calling out
JEFMAN,
AndersI,
Rondog, or anybody else that may know the answer.
i have a global image 7-10-7 and ours is set at 500mm/s under steup options (F5) part/machine tab toward the top is a top speed (mm/sec): option.
although ive never played with it so i dont know if it actually sets the machine speed limit or if its another one of those settings that hexagon put there to make us feel in control but actually doesnt do anything
So I think I have found dynamics figures for a lot of the recent machines. Unfortunately, not all the source documents can be found in one place, but luckily I have most of this data in one place gathered fron numerous quotes (with exception of Mistral and Scirocco). A few caveats, before we get to the actual numbers:
•USE AT YOUR OWN RISK!!! •These figures may not apply to all machine sizes for a certain model.
•USE AT YOUR OWN RISK!!! •These figures do not take into account probing systems, which may impose further limitations.
•USE AT YOUR OWN RISK!!! •These figures may not be correct at all. All are sourced from Hexagon documents (no third parties), but whose to say if they apply only to certain years of mfg., country, etc.
•USE AT YOUR OWN RISK!!! •Further limitations may be set in your computer or machine controller. Your mileage may vary.
•USE AT YOUR OWN RISK!!! •Other machine parameters may have an effect on realized acceleration or traverse speeds. Your mileage may vary.
•USE AT YOUR OWN RISK!!! •Keep in mind, the 3D speed is all three axis moving at full speed. I have calculated a single-axis speed, which is what needs to be entered in PC-DMIS.
•USE AT YOUR OWN RISK!!!
With all that said, here's what I found:

It's just weird all other machines everywhere I have been never this slow, especially a new machine. So you think I should try MM instead of %? not a big deal I can try that. Won't be able to get back with this until a later date
Not EXACTLY sure, since all the options and stuff will be different for different controllers, but under F5, Part/Machine, there is a setting for DISPLAY ABSOLUTE SPEEDS, a box to mark, then a place to put the speed (Sharpe32). I get the same on the Global (whatever it's controller is). How did you get to that page? Is that F5 or something else?
