Cloud Point Operator "CLEAN". Is this a Global feature and who's value carries over to the next program automatically.

Clean is an Operator that runs with each execution, and is calculated based on your current data. Once a COP is ran through the CLEAN Operator, that data then continues downward. The amount "cleaned" does not carry over per run, but is calculated each run when it gets to that line of code.

You need to be very careful when using the clean operator.  It is designed to remove points over the specified distance from the CAD surface, the intention being that, once properly aligned, you can easily exclude points that may have been gathered on the fixture or on clamps holding the part.  The danger is that you can also exclude valid data if you set the clean tolerance less than the amount of deviation present.  I would say a value of 0.03 is extremely likely to be removing legitimate data because 0.03 is lower than the accuracy spec of the laser - you're looking at about ±0.05 for a laser on a Romer Arm.  Generally, I use a large tolerance for the clean operator at least 1mm more than the amount of variation I expect there to be based on the drawing tolerances.  I then use the select operator to "trim" out any other areas - where clamps are contacting the part for example.

So that also applies to a different part and program....should have no effect from the previous program......correct???

Thanks

Correct. The clean COP only affects the COP it has a Reference to in the program.

COPCLEAN1 has a reference to COP1, which is in the current program.

COP1       =COP/DATA,TOTAL SIZE=3,REDUCED SIZE=3,
            FINDNOMS=NO,REF=SCN4,,
COPCLEAN1  =COP/OPER,CLEAN,MAX DISTANCE=0.04,APPLY MAX ANGLE=NO,
            SIZE=0,REF=COP1,,

Make sure you properly place Cloudpoint Empty and Purges where needed. I was told to put purges at the end of the program, but I personally did it at the beginning instead in case I want to look back at my data after a program has ran. I haven't used my HP-L-10.10 in months though, and am a bit rusty on Cloudpoint operators.

That's good to  know. By the way...the .030 is in inches not mm's.

I've tried tight tolerance parts with the Laser......Picks up a lot of the stress relief distortions. So i don't use the laser unless I have no other choice with those type parts.

Thanks
