Tantalum Marker Insertion Work Instructions

Doc: Tantalum Marker Insertion Work Instructions Rev. Date: 10/27/2016

1. Upon receipt of the Job Traveler and parts to be pinned, put on powder free nitrile gloves. Visually inspect the parts to verify that the previous deburr and cleaning operations have removed all blast residue and that the Tantalum pin holes are clean and clear of debris.

2. Log in to Vista ERP and clock in to production for the pinning operation. Prior to beginning work check the Shear Punch Maintenance Log to verify maintenance was performed. If the log is out of date perform the maintenance operations.

3. Verify the Pin diameter and length on the first page of the job traveler match the engineering drawing included from the customer. Sizes are typically .035” or .039” in diameter. The pins of .035” diameter are customer supplied material and can be obtained from the production/purchasing manager. The .035” Pins are pre-cut to length and the operator may proceed directly to step 10. The material for the .039” stock can be obtained from the material locker in the tool room.

4. Verify that the material lot number on the traveler matches the material lot number on the material tag attached to the Tantalum rods.

5. Determine what length the marker needs to be cut to using the front page of the traveler and verifying the length matches the callout on the engineering drawing.

6. Locate the appropriate size of pin catch tray in the labeled drawer. Size ranges are marked on the trays. Place pin catch tray in the slot under the Tantalum pin cutting tool.

7. Combine the reference gage blocks to set the length requirement of the Tantalum pin, as defined by the traveler and engineering drawing. Insert the gages into the vise jaws and tighten.

8. Insert the Tantalum stock into the feeder hole die using one of the two holes. Feed stock into the device until it reaches the solid jaw. Activate the shear punch by pulling down on the drill press handle on the right side of the device. The cut pin will drop into the pin catch tray.

9. Repeat step 8 until the quantity called out for on the traveler is reached. Remove the pin catch tray.

10. Visually inspect the cut ends of the Tantalum marker for proper form. There should be no distortion due to dulling of the shear punch. If the cuts ends are deformed send the shear punch blade for reconditioning. The Shear Punch Maintenance Log located in the Manuals and SOP’s drawer will then be completed by the machinist who performed the reconditioning.

11. Retrieve the pin cups from the labeled drawer and fill them with alcohol. Count the pins again as you move them from the pin catch tray to the pin cups containing alcohol. Keeping the pins clean is vital to the process. If a pin is dropped replace it in the alcohol before using. Place smaller length pins on the left of the workspace and larger pins on the right to keep them separated.

12. The PEEK parts can now be staged in the part tray labeled “Pinning Incomplete”. Count the parts to verify the appropriate quantity is on hand.

13. Retrieve the appropriate fixture from the fixture drawer and place on the workspace. Turn on the magnifying lamp and light up the fixture. Prep the fixture by rubbing with alcohol. Protect the PEEK parts by padding the bottom of the fixture with scotch brite, taking care to provide appropriate fixturing by maintaining a solid impact surface.

14. Place the part in the fixture. Thicker parts in the deeper slot and thinner parts in the shallower slot.

15. Using the tweezers located in the pinning kit drawer pick up a Tantalum pin and place the tip in the appropriate size hole (short pin in shallow hole, long pin in deeper hole) on the part per print callout. Using the tapper located in the pinning kit gently tap the tantalum pin into the hole until it is ¾ of the way down the hole. Maintain contact with the tantalum pin using the tweezers while tapping to ensure the pin does not bend. Once a depth of ¾ is achieved the tweezers are no longer necessary as the part will now prevent deformation of the pin.

16. Use the Pin Insertion Tool located in the pinning kit to complete the press of the marker. Carefully place the tip of the Pin Insertion Tool onto the top of the pin and gently tap into the hole until the pin is inserted just below the surface of the part.

17. Visually inspect the part to ensure the pin is equidistant from either end of the hole. Make any adjustments necessary at this time as the inspection will fail a part if the marker is not placed properly.

18. Finish all holes on the part making sure the correct size marker is placed in the correct hole per callout on the engineering drawing. Place the now pinned part in the tray marked “pinning complete”.

19. Once all parts have had the Tantalum markers installed conduct a final count. While counting, conduct a thorough visual inspection to ensure all Tantalum markers were properly installed and undamaged.

20. Clean the parts with alcohol following Turnco Tool and Instrument alcohol cleaning work instruction.

21. Log in to vista and clock out of production making sure to log the quantity completed. Sign off the OP on the job traveler and deliver the parts to Quality for inspection.
