P11581: Thread Roll Die Inspection

This will be fine from an operator standpoint. More functionality can be good for the engineer on the projects.
In about one inch from the edge is where they typically see issues show up. The edge of the die is important, the middle of the die not some much. That’s not to say that we don’t need the dimensions in the middle of the die. We will take as much data as possible now and then remove unnecessary portions.
PCC is interested in tool life, they are interested in the critical dimensions that will yield good parts. It is unknown how much back log data is needed since there is no data currently. For now it would be nice to save all of the data, measure everything, and then filter out the noise and the data that can be determined unimportant at a later time. PCC would like to track variation along the life of the tool.
Jenkintown facility does a lot of SQL but Excel will be fine.
Yes focus on the flat dies they are the majority of the products. The cylindrical ones can be measured with some contact measuring, but there is nothing in place for flat dies.
Currently there is no measurement system. The way a problem is determined is they measure the part after it comes off the machine. So no measurement currently for flat dies.
Thread forms are measured from one thread to the next, (the answer for the rest of the measurements was unclear)
If you look at a bolt, it’s where the thread runs out into the shank of the bolt. It’s at the transition from thread to shank. There is dimension to it that is critical. It might not be in the drawing that we (RIT) have but a drawing that includes it will be sent.
Certainly want these to all be parallel. (it wasn’t stated where the measurement can be taken from)
A plexiglass container around the unit is typical in our facility. Nothing will be slamming into it, there will be oil droplets and lots of oil mist in the air. The laser lens will need to be kept clean and the die needs to be clean to make sure that the measurements are accurate. There may be calibration part to validate the laser before measurements.
This sound like a great idea and PCC uses this now in other areas.
If the floors are not level it could affect the measurement. Shock resistance could be important. A stationary setup location can be good.
This (the die that we have) is pretty much the largest; the smallest is around #10.

PCC will supply a computer, just need to have our measurement system interface with computer.
