View Full Version : What does TCI mean? Test Capability Index = USL-LSL/6*sigma of the test only pfumvue 22nd March 2005, 09:47 PM Dear all~ Our cuscomer ask us about "Is a criteria established for gage R&R/TCI (gage R&R<10%,TCI<25%)", but we don't understand what does TCI mean. Hope for help. Thanks a lot. Annie howste 23rd March 2005, 01:23 PM Well, you've stumped me on that one. I've never heard of it. Anybody else? wmarhel 23rd March 2005, 01:36 PM Haven't heard of it. A quick search on Google didn't turn up anything useful, but a few references in conjunction with Gage R&R were found. I'm curious to know what this is as well. Wayne Al Rosen 23rd March 2005, 01:53 PM TCI = Test Capability Index. = USL-LSL/6*sigma of the test only howste 23rd March 2005, 02:43 PM So a TCI <25% would be equivalent to a Cp >4 for the test? Wouldn't that be dependent on the samples used, not the measuring system? Or is it using the variations in the reading for the same parts? |
