Poor tool change

Fault:

Poor automatic tool change, with loud noise.

Remedy:

With method “grabbing empty tool” can observe relative position of tool changer and taper of spindle. Found the position of spindle was slightly lower. By adjusting the MD34090 parameter of Y axis (REFP_MOVE_DIST_CORR, in the menu Start-up/Machine data/Axis specific) can raise its position. In this case adjusted it from -96.403 to -93. After resetting NCK the tool change was basically normal.
