WebOct 1, 2024 · Ksyuha. We have faced problems during measuring of wire crimp height for small types of terminals. We use crimp micrometers but it is diffiult to position contact in the appropriate position. Destructive cross section control is not suitable for us due to necessity to have SPC and also not to spend a lot of time for this control. WebOct 2, 2013 · An operator must teach the CFM what to identify as a good or bad crimp through the “teach-in” process. This consists of running several crimps and manually verifying that the data associated with that crimp (crimp force, crimp height, etc.) is correct. The CFM then compares all future crimps to this data. Therefore, in CFM terms, …
