I go with ( this is the overly simplified version mind you with MY LSPX-1s ) FEATURE Ø / 5 ( IN Millimeters ) But this is a huge surface / Ø. Looking at my LEVEL 2 DMIS book. It also says never go over 25MM /sec on UNDEFINED scans or over 150 for defined scans ( basicly taken from a cad model or learned from the part ). That being said your part would be 7.42 = 188.5 MM / 5 = 37.7. THats sounds crazy fast to me. BUT, most parts I deal with are ( aluminum extrsusions ) and are never larger than 6 in sq cross sectionaly so most features that I scan are smaller bores/holes. If I am scanning a surface , i have never really scanned over 10mm/sec. This is another good example of why you should also be running your CMM in MM/SEC vs. % speed. All the scanning formulas are based on MM/SEC. ( F5 / PART/MACHINE TAB / CHECK DISPLAY ABSOLUTE SPEEDS )
