We have a horizontal machining center with a Fanuc Series 16-M control. We need to back-chamfer (plunge) a hole, so we keylock the spindle, position in X & Y so we can feed through the hole, we feed in the Z-axis through the hole to get to the back, then we want to feed to the centerline in the Y-axis, start the spindle, feed in the Z-axis to desired depth, then reverse the process to get out of the hole.
The machine feeds no problem in the Z-axis with the spindle keylocked, but won't move in the X or Y-axis. Is there a parameter I need to change? Or is there another way to get through this? I'm stuck and the machine is down any help is very much appreciated...
Thanks
