Recall Alignment Corner

May 15

Hello Everybody!

I am new to Calypso and self taught. What would be the best method to using a recall alignment to a corner?

I know that I should be using the Start alignment but is there something that I should be doing to my CAD Model like have the CAD Model alignment where the recall point is at?

I know that in PC-DMIS and Zone3, all I need is to have my CAD model Alignment right in the corner of my fixtures where the recall point is at, and then from there I would no longer need a manual alignment and can just program the machine to locate my parts.

I really want to use a recall point to reduce the amount of times I would need to do a manual alignment and just have to manually relocate the Corner Alignment whenever the Corner is removed.

Thanks,

I'm a little lost on what you're trying to do, screenshots would help.

But in Calypso it's a different thought process than PC-DMIS. Your Base Alignment should be large, stable features that control all 6 Degrees of Freedom, and you should measure them in a complete enough way that you don't have to measure them again later.

If you want it to be in the corner of a rectangular part would like just use 3 planes ( Top, then two sides), or Plane (Control 3 DoF), Line on a side ( 2 DoF), then a point (1 DoF) for a 3,2,1 Alignment... it just depends on what's being measured...

In Calypso, many of the characteristics create their own coordinate systems (Alignments) so you don't need to measure things in various coordinate systems most of the time. A solid base alignment is all you need for most things, preferably one that makes the majority of your Basics on the drawing match.

Then when you make a Position or Profile to ABC, you don't have to create a secondary alignment using ABC, then measure your feature in that alignment. You measure that feature in Base Alignment, then you fill out the datums in the characteristics and Calypso gets your correct nominals - Most of the time.

A Start Alignment is most useful if your fixturing leaves room to wiggle, then you can use more forgiving, hopefully fast, features to roughly locate the part that can be set to manual run or automatic, then the Base Alignment will run after.. You can't define a Start Alignment until after you've made the Base Alignment, when you do it you'll see Calypso calculates the offset if any. I'll also warn you that if you modify the Base Alignment with a Start Alignment active, it does not always behave nice and you may have to recreate the Start Alignment.

If you have fixture-like position for a part, then easiest thing would be:

Make a program named with added "_fixture" with a model ( model is not needed ) where you setup base alignment and click a button for manually locate a part
Save this program as normal name ( without that additional text )
Edit base alignment by "Load saved alignment" -> select name with "_fixture" - this will prevent to measure BA

Now you have 2 programs - one for locating part whenever you move fixture and normal measuring program
