Question Description

Write this report as an Industrial Engineer in APA format (every pic must be labeled)

I have a lab report for manufacturing class, I need you to edit it and change in a way it looks different than the original report. I'll provide you with pictures to use instead of the ones in the report, and you can get the tools pictures from the internet if needed.

Also, you need to look at this page: which will show you the lab steps, how it's suppose to be done, and how to express the result.

Me and my team created a Nut which was not accurate, which means you need to justify it. The reason it was not accurate, we didn't determine the center of the Nut correctly, and the Drill was not stable when we drill it.

Since the report which I want you to edit it is 820 words, I'm going to choose 3 pages.

Introduction Bolts and nuts are industrial fasteners. They are daily consumable items in engineering industries. Bolt is a piece of metal rod, whose one end is unsettled and the other end is threaded. Nut is the item, which rolls on these threads. Bolt and nuts can be sold independently in the market. Therefore, manufacturers follow a standard in manufacturing bolts and nuts so that there is uniformity of the product in the market. The objective for this lab was to manufacture a hex thick nut by using basic tools used in manufacturing shops. The tolerancing and dimensioning of the nut was according to the standard table of Hex Thick Slotted Nuts. Design approach The design approach was plan driven, the design process was understood in terms of discrete sequence of stages. Theory and Calculations The following dimensions and tolerances were selected from the Standard table of Hex thick slotted Nuts. Basic major diameter = 3/8 F: max = 0.562, min=0.551, basic =9/16 G: max =0.650, min = 0.628 H: max = 0.415, min=0.398, basic=13/32 Experiment procedure Tools & Equipment: Hacksaw, files, vise, Vernier caliper, micrometer, blue dye, scribe, protractor, punch, drill press, thread gage, tap and die set, tapping oil. 1. A stock of 0.75 inches diameter was used. From the standard table of hex thick nuts, we selected a basic major diameter of 3/8 for our nut. The dimension was suitable since it would require less work producing the finished product while using basic workshop tools. 2. The stock was held firmly using a bench vice and the nut was cut out using a hacksaw. The cut was based on the calculation below: a. H max * 125% = 0.518 b. H max * 150% = 0.6225 Once cut from the stock the nut was shaved using a double cut file to obtain the dimensions specified in the standard table. Further smoothening was done using a mill. The workpiece obtained at this stage looked as shown below: 3. One surface of the nut was painted and left to dry. 4. A center square was then used to obtain the center line. And the center was marked using a scriber then made visible using a center punch. 5. On the surface of the nut, we used a compass to draw lines in the directions of 60, 120, 180, 240, 300 and 360 degrees so that we got 6 angles. 6. We then calculate F by using the following formula 𝐹 = 𝐹𝑚𝑎𝑥 2 so that we find F which is from the center to the top and we marked it on the nut. 7. We used two pieces of wood to hold the nut on vise to avoid damaging it. 8. We connected all the line on the surface of the nut and then we used the double cut file to cut each side of the nut to shape as nut. The nut looked as shown below: 9. We then placed the nut in a drilling machine. And we made a hole through at the center of the nut. 10. We then held the nut on a vice and using a tap and die set we made internal threads on the nut. The process involved to round once and go back for half round. Discussion of the results and corrections The final product we obtained from the experiment above is as shown below: By analyzing the dimensions and appearance of our nut, we found it to be not exactly what we expected. The hole drilled was not at the center of the nut. The dimension F was also not consistent throughout the nut. The thickness was also not the same throughout the profile of the nut. However, we managed to obtain good threads. The unexpected result could have been brought up by: 1. Poor alignment of the nut when drilling. By not putting the nut in the correct alignment it caused the center to be missed by the drill bit in the drilling machine 2. Another source of error was the ineffective use of the available equipment, this resulted in the varying side dimensions of the nut. Product Cost: My working hour is $10 My group and I spent 7 hours to have the product complete. The material cost $10 So, The product cost in manufacturing: ($10*7) + $10 = $80 The product will cost out of manufacturing: 80*3 = $240 Conclusion We managed to use simple workshop tools to make a sample nut. We learnt how to use a tap and die set to make internal threads. We also learnt the important parameters used in making a nut as well as other basic skills such as using wood to prevent damaging a workpiece on the vice. To improve on the accuracy of making a nut, we encourage using accurate machines to make the nut ...

Some of the most on demand consumable daily items in the engineering industries are
bolts and nuts. These items are usually used for fastening purposes. A bolt is simply a metal rod
with one end being threaded and the other is unsettled, while a nut is an item that is rolled on the
threads of a bolt during the fastening exercise.
Manufacturers are always required to adhere to bolts and nuts manufacturing standards
when producing these two items since they are usually sold independently in the market. This is
meant to guarantee uniformity of the two items after they have been purchased
The aim of this lab session was to manufacture a hex thick slotted nut using basic tools
that are commonly used by manufacturers. The standard table of Hex Thick Slotted Nuts was
used to determine the nominal size of the nut that was to...
