Hello,
I just had a project dumped in my lap that I need some help with.
We have a grinding machine that has two grinding wheels. One wheel is in a fixed position and the other wheel (called the regulator wheel) indexes inward as it's surface wears down.
This machine has an infeed table that is feeding round bars of steel into the grinding wheels. As the bars are being ground down, the regulator wheel gets smaller from wear so it must index inward (about 3 thousands) every so often. This is controlled by a measuring device on the outfeed table (zumbach laser mic) that in turn pulses a hydraulic solenoid to inch (ever so slightly) the regulator wheel inward. The amount of travel is controlled by the human operator(hydraulic valve adjustment).
How can I track the regulator wheel movement and accordingly adjust the infeed table to match this position? I only need about +/- 5 thousands accuracy . The infeed table has a 110 volt ac motor (63rpm) with an attached gear box (40:1). No brake.
Not sure how to tackle this problem.
I would really appreciate any suggestions. We don't have an EE on the payroll so I'm on my own with this one.
Thanks for any suggestions
