Procedure

    1. SUBTASK 72-41-11-110-066 Clean the Surfaces

      1. Clean the disk assembly.

      1. Refer to the SPM TASK 70-11-34-300-503.

    2. SUBTASK 72-41-11-320-052 Machine the Damping Wire Location Slots

      1. Set up the disk assembly for machining.

      1. Use IAE 3R18735 Turning arbor 1 off with centre lathe.

      2. Use dial test indicator to ensure disk assembly runs true.

      2. Face off angled surface at the rear of the stage 8 dovetail slot leaving the 0.028 in. (0.72 mm) to 0.032 in. (0.82 mm) dimension intact.

      1. Use standard turning tool.

      2. Flat surface required to avoid deflection/breakage of fine groove tool during machining.

      3. Refer to Figure.

      3. Machine the damping wire location slots at the front of stages 7 and 8 blade root location slots.

      2. Refer to Figure and Figure.

      4. NOTE

        Do not machine to full depth of above, allowance for final machining is required.

        Machine the damping wire location slots at the front and rear of stages 7 and 8 blade root location slots.

      2. Refer to Figure and Figure.

      5. Remove sharp edges.

      1. Use standard turning tool.

    6. Remove disk assembly from machine.

      7. Set up the disk assembly machine cusp at stage 7 location slot.

      1. Use 0.160 in. (4mm) dia. ball-nosed milling cutter with standard milling machine.

      8. Machine to remove the cusp.

      1. See Figure and Figure.
