Hi,
We have 3 small sinker EDM machines we use to machine stamping dies for our engraving business. This past couple of weeks we have been very busy (yay!) but have noticed a strange phenomenon with the way our CNC is cutting our carbon/graphite electrodes. We have been experiencing uneven cuts -the variance on the letter heights on 1 stamp die we did is over 0.010"! Some of the part numbers come out looking like they had a wild party (not lined up...crooked, just plain "goofy" looking).
Since we have not had this type of problem before (probably because we never had all 3 EDM's running at the same time), we were wondering if the radio frequency waves from the EDM's could be affecting the encoders on our CNC.
If this is the case, would grounding each EDM to Earth be a solution for this problem?
Any insights would be greatly appreciated.
Thanks!
Yvonne
