correct way to setup and check profile tolerance of the part using Laser scan

I am quite new to Laser scan.. Please advise quick and correct way to setup and check profile tolerance of the part using Laser scan on different type of material as Aluminum, Casting part...

Hardware:

7 axis Absolute Romer Arm with Laser Scanner V3P/8525

SW:

PC-DMIS 24.12 CAD++ Scanning/MESH ARM /RDS latest version

Part:

1> Casting  (profile tol. spec from +/-0.030"

2>Mixed Aluminum   (profile tol. spec from +/-0.010")

3>Steel   (profile tol. spec from +/-0.010"

Thanks so much

  • Align the part according to your datums.

    Scan the part.

    Apply colormap (CAD needed, tolerance ± half the profile tolerance). Apply deviation flags to your liking.

    I have found that this is the easiest way to show non-metrologists the state of the surface profile.

  • What is your scan setting for different type of surfaces as Casting, we have hard time for laser scan to pick up ?

    And also if the part was under cut let's say 0.01"- 0.040" on very small narrow pass, how to adjust the scan pitch setting?

    Thanks 

  •  Have you had any PC-DMIS Portable training?  A lot of what you are asking would normally be covered during one of our training courses.  There is also a lot of information in the online help files.  For example, this is the section that covers customising your data collection settings: Profiles Section.  There are also other setting within the RDS software which handles the connection between PC-DMIS and the arm.

  • V3P scanner, never heard of it. We have RS6 and the default standard setting (in PC-DMIS) seems to work fine. In RDS, Shine is enabled.

  • Haha, did you buy your RS6 within 2 months of it being discontinued? Cause we sure did! (They were SUPER happy to learn that one!!)

    "I'm sorry those upgrades are not compatible with your laser."
    "But its less than a year old!"
    "Have your seen our new AS1 scanner?"
    "What makes the AS1 better than the RS6?"
    "Nothing really, its the same hardware inside, it just says AS1 when you plug it in!" 
    "Oh....neat!" 
    "Would you like to replace your brand new scanner with an AS1?"
    "No thanks...."
