Roomer Arm Infinite VS non controlled Temp.

Can anyone in here direct me to where is shows that the Infinite 2.0 can be used in a un contolled temperature enviorment ? Is there any limits on the temperature ?

Thanks,

  • Got the latest book right here. For the infinite 2.0, volumetric accuracy STARTS at .0006" for the 4 ft arm, and goes up to .0027" on the 12 ft arm. Point repeatability ranges from .0004" to .0020". And those stats are for the 6-axis model.

    For the 7-axis, vol acc is .0014" to .0040", and point repeatability is .0009" to .0028". That is for a range of 6ft to 12ft (no 4ft arm in 7 axis).

    Wish I had it in pdf for you, but if you want a specific size, let me know.

    AND, keep in mind, those are SALESMEN's numbers as opposed to REAL WORLD numbers. In other words, those are the BEST CASE SCENARIOS they were able to get, not the real world actualities.
  • And that's at 68 deg's btw. They are constructed of carbon fiber, so I guess they be a little more resistant to temp flux, but it is still a factor.

    +1 for that.
  • Did I hear my name? Hello Phillip and Josh. Phillip, you have a 5024SC arm which is to say that you have an 8' 7-zxis arm. The stated accuracy of that arm is .0016" on the volumetric length accuracy which means that as Josh stated there is no way to meet the requirement of 0.0002" accuracy. Well I should not say no way, but iven if you do attain 0.0002" you cannot be certain of that with a portable CMM. It just doesn't exist except in bridge (stationary CMMs). I'm inb the office call me if needed!




    Well I'll be....Hi Scott! Thanks for the help!
  • What you really need is a combination of a lift truck and a gantry CMM. Instead of the forks on the lift truck, the forks would be the ways. You could just drive it up to a work station and park that SOB right on top of the job you want to check. Stationary CMM accuracy in a portable unit... I luv it. And HEXAGON, if you use that idea, can you buy my family and myself a steak dinner or something. My kids are young so they'll take hotdogs still. A nice ribeye for my wife and I though. Thanks...

    Actually they are B89.4.22 numbers. These values are detemined using B89.4.22 measurement methods which dictate arm ariculations over while measuring a known length standard. Articulating the arm increases the VOLUME on an articulated arm. Less articulations means more accurate. If articulated less THEN the numbers would be BEST CASE SCENARIO but not real world. This is a manual machine so being smart about the articulations can insure highest level of accuracy. With a DCC CMM you wouldn't unneccesarily drive around the part for no reason as that too would add to the machine uncertainty.
