Thank you for the report on correlation coefficients. The manufacturer of the sampling machine sent a header file for the API. They said that should tell you all you need to know.
We are wiring the machine up to our production equipment now. The channel assignments we will use are
1. Ambient Temperature (deg F)
2. Drill Speed (RPM)
3. Coolant Temperature (deg F)
4. Hole Position (mm)
The remaining channels are unused at this time.
We are looking for correlations of the first three with hole position. Our operator will specify the parameters we want to monitor at the beginning of a batch and we need you to print out the correlation coefficient at the end.
It would be very nice if we could get some kind of graphical output too. Is there any way you can do that?
