After data entry, the system indexes the elevator, positions the
first tray and moves the tray to the X/Y loading station.
A "pick and place" arm removes the
part from the tray and loads it into the spindle nose. The loading arm has
dual or quad end effecters for insertion and removal of either blocked
parts or blanks from the spindle nose and the loading trays.
During the roughing cycle, the arm
returns the cut part to the holder, picks up the next part and waits for
the finish cut to be completed. This keeps load/unload time
to a minimum.
All
loader movement is completed prior to the start of a finish cut to minimize
vibration.
