Hi all! I love this forum, and have finally official joined to get help for my specific problem. I appreciate any and all wisdom that can be offered!
My boss (who I call dad) bought a cnc mill that was a repo a local dealer was trying to unload. The price was good, but we're not familiar with the controller (seimens sinumerik 808d) and service hasn't been great.
So far for every job we've run we've used programs we have on our old fanuc mills, and everything has worked fine except the g84 tapping cycles.
The "cycle84" generated on the 808d makes sense, but isn't working. When the tap reaches the bottom of the hole (dry run), the spindle stops and the screen says "wait: exact stop not reached". After a second or two we get alarm 025080 axis sp positioning monitoring.
So far we haven't been able to get the spindle to reverse out of the hole. If I do straight tapping it goes to the bottom of the hole and stops. If I add chip breaking, it stops at the first reverse point and gives the same alarm every time.
Could we be making a mistake in our program? (I can post a sample program). Is there a possible parameter issue going on? Are there resources available that someone can direct me to?
I'm open to and grateful for any thoughts you all may have!
