Returning to Part Sampling and Correlation…
One of our customers could not get the Part Sampling tool to start on a validated eDART (October 23, 2003 software release). We’re not yet sure why. It is supposed to be there. I wrote some help to him to get him going since he had a big DOE starting with a bunch of people looking over his shoulder.
This brings up the subject of what to do about part sampling if you forget to use the Part Sampling tool to mark the parts. We recommend that you always use it because it tells you exactly which part to take from the machine and lists the time stamps as each is sampled. Sometimes people forget and run through several runs and then have to go back and sort of retro-sample the parts. This can be done either on the eDART’s Summary Graph or on the Analyzer.
Or course you MUST record (on paper or a bag of parts) the shot time stamp at which each part group started. So here are the steps in brief:
Part Sampling Entry without Part Sampling Tool
If you forget to run the the Part Sampling tool or it is not in the system or will not run then enter the sample groups manually on the Summary Graph as notes. Here’s how.
You can also enter these notes later in the Analyzer on a windows computer if you do not have time to do it at the press. Just be sure you carefully mark the parts (bag them) and record the exact time stamp for each sample.
