PROCESS 8 Hinge Pin Grinding PROCESS 9 MIG Welding Hinge Pin PROCESS 10 Rectangular hook welding ALUMINUM BRACKET PROCESS 1 Cutting the Aluminum Stock Horizontal Band Saw Setup time = 3 minutes Cycle time = 1 1/2 minutes 1. Use Fixture BR201 and the aluminum bar stock from reserve next to scrap bin 1.Use Fixture BR201 and make a line 4.6" from the end of the 1" x 1" square bar stock 2. Ensure machine is unplugged and check the speed: set it to the proper speed for aluminum as indicated on the black chart on the yellow box to the right. Open the yellow box by unscrewing the black knob. The belt should be set to the position on the 3rd from the top alignment also as indicated by the black chart. If it's not at the correct position, on the green motor next to the yellow box, loosen the half inch bolt using a half inch socket, wrench, or pressing wrench. From there, change the location of the belt as needed. To close the green motor, have a second person pull the motor upwards until the belt has tension, while tightening the bolt back. Close the yellow box and reattach the knob. 3. On the left side of the bandsaw you will find an aluminum handle. Grab the handle and lift until the saw portion of the machine stops in up position (there should plenty of room to fit material under the blade). Ensure that the machine drop rate is left on 0 until you are ready to cut. 4. You can now insert the 1" x 1" bar stock from the rear of the machine. Make sure the stock is flush, 90 degrees, against vice. If the tube extends more than a foot off the back of the machine, place the green support bar under it. Ask for another person to help if necessary and make sure to hold the bar when adjusting its height so it doesn’t drop and pinch your fingers. Ensure that the stand is at the same height as the machine so the stock sits flat. 5. Make sure that the machine is plugged in and set to cut aluminum (follow the horizontal band saw instructions posted in lab, if you need help to change the setting ask an ISA: ), then on the control panel, located on the top middle of the machine, turn the drop to “ON” and turn the drop speed knob to between 23. Then slowly lower the saw until it is 34 inches from the workpiece. Looking down at the blade and workpiece, adjust the workpiece (using a rubber mallet to avoid cutting your fingers) until the line on your piece is in line with the saw blade.
- 14. 6. Once the blade is lined up with the line you made on the piece, grab the handle on the left of the machine (attached to the wheel) and turn it clockwise to lock the vise. 7. Now to make the cut, lift the top half of the machine until it is in the up position again. Make sure the coolant knob (has a sink icon above it) is in the "I" position. Push and twist the emergency stop button clockwise until it pops out (third button from the left). Turn the drop knob to “ON” and begin to slowly lower the saw by turning the drop speed knob counter clockwise. As the blade comes into contact with the metal (your piece), your speed should be between 1.5 and 2, and once the blade is fully engaged with the part, you can increase the speed to between 2.5 and 3. 8.As the blade gets close to finishing the cut, put one hand on the work piece to make sure it does not fall or shoot off once the cut is made. 9. Once the blade is finished cutting the workpiece, hit the emergency stop, turn the speed to 0, and turn the drop knob to OFF. Lift the top half of the machine and remove your part. Check with calipers to ensure it is no less than 4.505” 10. Mark 4.5” again on the stock and slide it forward in the vise. Repeat all steps of the operation until all the stock has been cut. 11. To clean the machine, make sure it is turned off and unplugged. Put all of your materials away and store the support close to horizontal band saw. Then sweep up around the machine and throw the swept chips of materials into trash can. 12. Take the finished part to either the cage, the Sandblaster (for steel tube stock), or CNC (for aluminum stock).
- 15. PROCESS 2 Milling the Bracket Setup time = 8 minutes Cycle time = 23 minutes 1. Acquire aluminum bar stock that was cut with the horizontal band saw at 4.6” in length and two parallel bars that measure 1.5” tall. Also grab cutting fluid. Place each parallel bar on the inside of each of the vise jaws of the Bridgeport manual mill. The vise is located on the middle area of the table on the mill. 2.Place the bar stock in the vise that is located on the table of the mill so that one edge of the stock is hanging over the edge of the side of the clamp by about ½” to 1” and the length of the stock is resting on the parallel bars. Simultaneously tighten the vise by rotating the handle at the front of it while using a rubber mallet to tap on the top of the stock to make sure that the stock lays perfectly on the bottom of the clamp during tightening. The bar stock should be gripped by the vise jaws, lying on the parallel bars, with the majority of the stock protruding upward and up to an inch of the long side hanging off. 1. Turn on the manual mill by plugging the power plug into the wall on the base of the mill and turn on the coordinate display by flipping the on switch near the display. 2. Insert a 3 flute ½” flat nose end mill into a ½” R8 collet and insert the collet into the receiving part of the mill. Hold the collet and tool up into the receiving part of the mill so
- 16. that the cutting edges of the end mill are held outside of the collet and, at the same time, press the “IN” button on the top left portion of the mill. Hold the “IN” button down until the collet and mill are pulled up and held securely in the mill. 3. Measure the exact length of the stock using calipers and note the length to determine how much material to remove on both long sides of the bar stock. Two sides of the bar stock will be faced, so the total extra length of the stock divided in half will be removed from each end. For example, if the stock measures 4.600” long, then .050” must be removed from each side by facing the sides to make the length of the piece measure exactly 4.500” +.05”. Use cutting fluid accordingly. 4. Locate the Digital Read Out (DRO) machine hanging to the right of the mill. Adjust the face of the DRO so that it can be easily read while rotating the X and Y axis handles. Locate the power cord on the back of the DRO and plug the cord into a nearby AC 120 outlet. Locate the metallic ON/OFF switch on the front face of the DRO and flip the switch to the ON position, the face of the DRO should light up. Next, locate the Inches/Millimeter metallic switch directly opposite of the ON/OFF switch. Flip the Inches/Millimeter switch to the Inches setting. 5.To begin facing one of the ends, zero the Xaxis with touch paper by moving the end mill very close to the side of the bar stock that is hanging over the edge of the vise and hold touch paper in between the stock and tool. Move the touch paper around while moving the Xaxis to move the tool into contact with the touch paper. Once contact has been made and the touch paper stops moving, press the “X select” button near the display and then press “CLR” to set the X coordinate to 0.000”. Move the tool off of the bar stock using the Xaxis and use the Yaxis to move the tool away in the perpendicular direction. Move the Zaxis so the end of the tool is about halfway down the height of the bar stock. 1. To make the first facing cut, move the tool in the Xaxis direction to the specified length that was determined through measuring the bar stock. For example, if the bar stock was
- 17. measured to be 4.5900” in length, then move the Xaxis so that the display reads “0.0450”. Apply cutting fluid to the end of the bar stock by rubbing or spraying it out of the cutting fluid bottle onto the workpiece. Now start the mill by flipping the black switch located near the “IN” and “OUT” buttons to the “LOW RANGE” setting. The end mill will begin to spin. Once it has sped up, turn the knob on the right side of the speed indication display (which is located directly above the cutting tool) to set the speed of the tool to 2200 rpm. The speed of the tool can only be adjusted while the mill is running. Now move the Yaxis so that the tool moves toward and through the bar stock which will shave off the appropriate amount from the side of the stock. 2. Once the tool has moved all the way past the width of the bar stock, the first cut is complete. Now move the Zaxis so the tool moves down to reach the bottom of the bar stock. Next, move the Yaxis so the tool makes another pass and shaves off the the rest of the protruding material. 3.Turn the mill off and remove the piece from the vise. Rotate it so that the opposite end is now hanging out of the vise and repeat the above process to face the other side. Remember to keep applying cutting fluid whenever a new cut will be made. 4. Once the ends are faced, rezero the xaxis in the same fashion described in the previous steps, and zero the Zaxis. To zero the Zaxis, rotate the knobs to move the Zaxis above the bar stock and slowly lower the Zaxis towards it. Use touch paper between the aluminum bar and the tool. Once the touch paper is slightly trapped between the bar and tool, the axis can be zeroed by loosening the dial and manually rotating the dial to read “0”. Then tighten the dial. After, back the tool off on the Yaxis so it is clear of the bar,
- 18. and rotate the Zaxis clockwise 7 times in order to move the tool up into the cutting area to create a .7” deep cut. 5. When ready to cut the channel: Use cutting fluid accordingly and rotate the Yaxis to move the tool to begin cutting at X= 1.000” and Z=0.700”. For the first and last cuts, use the locking mechanism for Xaxis (located under the platform) to get precise cuts as the axis may move due to vibration. Repeat the same horizontal cuts moving down the workpiece by setting the Xaxis on the display to: 1.3”, 1.6”, 1.9”, 2.2”, 2.5”, 2.8”, 3.1” 3.4”, 3.7”, a little more or little less is fine for middle cuts, but make sure to make a cut at 4” exactly for final cut. 6. Remove the completed piece from the vise and move it to stock shelf above the label “Milled Bracket”. PROCESS 3 Drill Press Setup time = 5 minutesCycle time = 19 minutes 1. Grab the jig labeled BR 205, the other jig labeled BR 208, a newly bracket that has been tumbled and milled, a 11/64” drill bit, a 25/64” drill bit, a center punch, and a hammer. 2. Align the BR 205 bracket with the inside of the milled part of the bracket so that the holes are vertical with the length of the bracket, the holes press up against the bottom of the milled edge, and the perpendicular part of the jig is pressed against either the right or left sides of the bracket. 3. Now, push the BR 208 bracket all the way on to one of the top or bottom ends of the bracket so that the side of the bracket labeled “back side” is on the same side as the back
- 19. side of the bracket and the top or bottom of the bracket is pressed all the way into the jig. 4. Mark the bracket holes using the center punch and hammer. For the top and bottom marks, remove the jig after marking one and use it to repeat the steps to make another mark for the opposite side. 5. Place a 11/64” drill bit into the chuck jaws so that it hangs down to be pushed into a part. To open the chuck jaws, use the red chuck key that hangs off of the drill press and insert it into the hole near the teeth of the chuck. Turn the key counterclockwise to open the chuck, put the drill bit in so that the jaws will tighten onto the side without flutes, and rotate the chuck key clockwise to tighten the jaws down snugly onto the drill bit. 6.Place the bracket into a vise so that the vertical line side is facing upward and tighten the vise by pulling the lever on the side of it. Place the vise with clamp on top of the drill press table so that the drill bit lines up with one of the etched holes on the bracket. Clamp the vise to the table using a clamp. 7. Turn the drill press on by plugging it in and pressing the green START button located above the chuck area but below the speed adjust. 8. While drill press is on, adjust the speed to be between 9001000 rpm by turning the handle above the on and off buttons. Make sure that the drill stop to the right is moved all the way to the top. Turn machine off by pressing the STOP button below the start button. 9. Align one of the previously etched areas on the inside of the bracket with the bottom of the drill bit by moving the vise around on the table. 10. Apply cutting fluid to the location that the drill will plunge into the bracket. 11. Using your free hand, rotate the handle on the right side of the drill press by pulling down on one of the large handles on the pilot feed lever. The drill bit will lower and eventually plunge into the bracket.
- 20. 12. Keep lowering the handle until the drill bit plunges all the way through the bracket. Release the pilot feed lever and turn the machine off by pressing the red button that is near the start button. 13. Repeat the above steps for the final two etched areas on the bracket. 14.Replace the drill bit with the 25/64” drill bit by following the above steps. Slow the speed down to around 300 rpm using the above steps. 15. Reposition the bracket in the vise so that it points up vertically and align the center punched or marked parts with the drill bit. Repeat the above steps to plunge the drill bit into the bracket. 16. After drilling, turn the bracket 90 degrees in the vise to repeat the process for the opposite side. 17. Remove the bracket from drill press and vice for countersinking. Before leaving the drill press area make sure the machine is off, vice is removed from drill press table and placed on the foot of machine and drill press table is brushed off. 18. Retrieve the 18v cordless drill from inventory locker and ¼’’ countersink tool and place at a workstation with drilled aluminum bracket. 19. Instal the battery by sliding the 18v battery pack onto the base of the cordless drill with the white button facing forward.
- 21. 20. Locate the oval directional drive button above the trigger of the driver but below the branding. Find the side on the serial number side with the arrow on the button pointed forward. Press the button down for clockwise rotation of the ¼’’ countersink. 21.Push the black knurled tool holder away from the driver and hold to install the countersink bit. Insert the ¼’’ countersink bit into the driver with the hexagonal end going in first. Once the bit is seated to the back of the cordless driver chuck, the black knurled sleeve can be released. Slightly pull on the countersink to ensure it is properly secured.
- 22. 22. Place the aluminum bracket in a vice with aluminum soft jaws in place and tighten. If aluminum soft jaws are not in the vice already, they can be retrieved from a nearby vice or tooling room. 23. Countersink the three middle 11/64” holes by slowly loweringf the countersink tool into the drilled holes in the most perpendicular angle possible. 24. Slowly squeeze the trigger between ¼ to ½ of a pull. Do not fully squeeze the trigger. 25. Countersink until approximately 35mm of radial countersink shows. Use the following picture for referance. Measuring with a ruler is not necessary. Instead put a number 8 fastening screw in the hole, the screw head should be flush to slightly recessed with the aluminum bracket 26. Repeat until all three middle 11/64” holes have been countersunk. 27. Remove the finished bracket from the vise and place into the “finished brackets” box. PROCESS 4 Tumbler Setup time = 1 minute Cycle time = 60 minutes 1. Locate the Tumbler and remove the lid by unscrewing counterclockwise the center locking knob on top of the lid. The locking knob may be loosened by turning the knob in the counterclockwise direction. 2. Remove any aluminum parts inside the tumbler but leave the dark, cylindrical chips. Place any found aluminum parts in a secure location.
- 23. 3. Replace the lid but do not fully tighten the center locking knob. 4. Retrieve 15 milled Aluminum bracket from stock shelf labeled “Milled Bracket”. 5.Remove the lid again by unscrewing the center locking knob on the top of the lid and place 15 milled aluminum brackets into Tumbler hopper. 6. Place the lid back on top of the Tumbler and tighten the center locking knob. The knob may be tightened by spinning it in the clockwise direction. Tighten the knob to full hand strength, do not use tools to over tighten the knob. 7. Plug in the Tumbler to AC 120 wall outlet. To turn the Tumbler on, locate the ON/OFF wheel on the power cord. Roll the wheel in a clockwise direction to turn the machine ON. Leave machine running for approximately 60 minutes. 8. Once time is up, check to see if bracket is finished by making sure there are no sharp edges and the finish is an even matte. If the finish is not matte, place the bracket back in the Tumbler for another 60 minutes. 9. Once an even matte finish covers the bracket. Remove the aluminum bracket and return the bracket to the stock shelf.

There are slots which hold the products in place to ensure that the products do not fall out. Another added feature is that a part of the box folds inwards which snaps the bottom bracket in place. This is all part of the dieline and does not require any extra material. ● Communication ○ Pull out tab on the top. This is communicates with the consumer without having instructions on how to open the box. The tab perfectly allows easy access to opening the box. The package has a sleeve to communicate with the consumer on what is inside. Another way of communicating with the consumer is through the window. After removing the sleeve, the consumer can easily see what is inside of the box. ● Protection
- 78. ○ The box protects the product from scuffing while being shipped from one location to another. The package spaces the products out enough to prevent impact from one another as well as protection from the outside environment. ● Convenience ○The bike rack package is easy to hold and is very sturdy. The box can easily stack several other packageproduct on top and still hold. Another great feature is that the package is great for display so when the consumer is moving or does not plan on using the bike rack, he/she can leave the bike rack in the package to display in his/her room. ● Environmental ○ All on one single die line, made of corrugate and solid bleached sulfate. These materials are commonly recycled and reused. Hours Worked By Team
