how do I do a simple scan?

I am an experienced programmer but never used a scanning head, I currently got employed by a company with a nice scanning head and want to scan this big gear insert for profile but I am having a hard time figuring this out. I kind of thought it would be as simple as selecting the cad area to be scanned and clicking create but its proving to be not that easy... unless I am missing something, which I am sure I am...

Any scanning wizards out there?
  • Its a 5 day training class with not alot of simple answers. I would ask that they send to the Hexagon Facility outside of Chicago for the class. A linear Closed scan should work. So many variables on scans. Cad or NO Cad ? I will always verify all the cad model surface vectors are correct on the surfaces I am dealing with before I create the scan. Smallest RAD will determine your scan speed unless you want to speed it up and slow it down ( this adds a whole new level to what you are trying to do ). Do a little resarch on scanning here in the forum and the good old F1.
  • It's simple....do a scan......LOL

    P.S. I'm not a scan wizard.....but I hope that helped.
  • What kind of scan are you looking to do?

    Linear open? Linear closed? Patch? Perimeter? etc...

    There is a little more to it than just simply scanning. What size probe? what type of hw (sp600/sp25)? machine settings? CAD vs no CAD?


    Other questions would be: did you do a full scan calibration for the probe you are using?

    Are your probing parameters set correctly?

    Offset force for an SP25 would be 0.1 with a point density of 10 or more

    Direction 1 tech is to set at Nullfilter, In Exec Controls RELEARN, probe comp is on,CAD comp on(if using CAD). In Nominals Method MASTER. Hit Controls VECTOR

    +1 to training.
    I fancy myself as a rather idiotic TTP scanning maverick, but if my company decided to go analog, I would definitely BEG 'em for some training. F1 works in many cases, am guessing this is not one of them.
    (plus, at training... you can crash THEIR stuff, not your own...) Rolling eyes

  • The concept of a liner open scan is first hit is your start point, second hit direction, 3rd hit end point. Click generate scan and voila. Closed scan you only jave start and direction point. Patch scan you select a bunch of points and it follows the points. Make sure you select generate scan before executing
  • First, you have to set good parameters for the scanning head.
    Long time ago, I started with basic scans, which are easy to use. Just be carefull to unselect "measure" (the cmm starts to scan when you click "OK", the crash is not far !!!!!).
    You can try analog scan strategy on auto features, it will give you some training.... And then, go to linear, patch...

    5 day training!

    I got 2 four hours sessions in-house! Disappointed
    That was with a new scanning machine with newer version software. Disappointed

    But you know how to do it !!!!! Sunglasses
  • Maybe its just me but scanning is very easy. And never understood need for a 5 day training course. First what type of scanning head? Do you use cad? If you would like to discuss over the phone we can arrange that. Scans are very bacis
