General Mach Discussion / Self Changing Velocity
« on: April 24, 2017, 02:35:44 PM »
I was having a problem with three minitech machines loosing their Z height in the middle of running jobs, resulting in inappropriate depths machined into the items I'm running, as well as a Z axis plunge. The change in the Z height was random, there wereno set depth changes. I believe the issue was that the velocity on the machines were set way to high, which brings me to my actual question/problem. I have not changed the velocity myself.
We have five machines, three of which were serviced. The ones serviced all had a change in their velocities. The machines not serviced are fine. No one has access to the machines other than three operators, myself included, and the person who serviced the machines. I tried contacting the company that serviced the machines but they believe we changed the velocities on our own, they didn't seem to believe me when I said we had not adjusted anything. They also believe the issue is resolved as we changed the velocities back to their original setting per their instructions.
While our machines were being serviced the person said they did find a velocity that was too high on one of the machines and changed it back to normal. With that said, I don't know what to do. The velocity on one machine was found raised too high, adjusted, and then was raised again. Non of which we did. I cannot think of what might be changing the velocity. I asked the company if it was possible that something was triggered or there was a chain reaction of sorts to change the velocity during the servicing. I was told to not adjust the velocity as a response. Our machines cannot be run overnight (which is their intended use) if we cannot trust that the issue won't occur again.
Any thoughts, opinions, insights, etc. would be greatly appreciated.
