Cause for Corrective Action

We as a group have not had to deal with as many problems as we did coming from gate one. During gate 2 we able to fix the problems that we were having originally. We now had better time management which eventually prevented many other issues that we had, such as being disorganized and not being able to finish gate requirements. With this gate, we have a few more issues that we will need to be able to address. Firstly, we will have to deal with the ability to access modeling programs. We have all already tried to download the type of Autodesk Inventor that we are all familiar with, and have not been successful in doing so. We can now either try to make this program work, or find times to go to the labs in Bell hall or Furnas hall. This is something that we will need to address early on individually based on our own personal preferences and availabilities during the week. This also seems to be the longest and most intensive gate out of the ones that we have completed so far, so we will need to stick to a strict schedule to make sure that we do not fall behind and end up rushing to complete it in the last minute in the last minute. So if we stick to the plan that we had for gate one, and keep in mind the extra challenges that we will have to face on this gate, then we shouldn’t have any problems.

Component Summary

Part #	Description	Image
1	Axle Rod Function: It is the center point for the Dart Advanced Drum. It allows rotation and feeding of darts into the firing chamber. Materials Used: Plastic and Stainless Steel. Manufacturing Process: Plastic- Injection Molding. Stainless Steel- Forming (Drawing).
2	Magazine Housing: Function: To provide protection from battle debris for the Dart Advanced Drum as well as provide rigidity for the magazine housing. Materials Used: Plastic. Manufacturing Process: Injection Molding.
3	Dart Advance Drum: Function: Holds the ammunition ready to be loaded into the firing chamber. This system is spring loaded which allows for the system to constantly force a new dart into the chamber. Materials Used: Plastic and Stainless Steel (leaf spring). Manufacturing Process: Plastic- Injection Molding. Stainless Steel- Rolling.
4	Rapid Feed Assist Knob Spring: Function: Provides pressure against the Rapid Feed Assist Knob to keep it from constantly engaging. Materials Used: Stainless Steel. Manufacturing Process: Forming.
5	Magazine Housing Cover: Function: Keeps dart from falling out of magazine. Allows the user to see inside drum to see any problems with the magazine, such as jams. Materials Used: Plastic. Manufacturing Process: Injection Molding
6	Rapid Feed Assist Knob: Function: Allows the user to manually twist the Dart Advanced Drum, which prevents darts from jamming. Materials Used: Plastic. Manufacturing Process: Injection Molding.
7	Push Rod Lock: Function: Locks the firing mechanism on the push rod. Keeps the mechanism at full potential. Materials Used: Plastic and Stainless Steel Manufacturing Process: Plastic- Injection Molding. Stainless Steel- Forming.
8	Firing Barrel: Function: Guides the dart out of the firing chamber. The rifling within the barrel puts a twist on the dart, which allows for a more accurate shot. Materials Used: Plastic Manufacturing Process: Injection Molding.
9	Muzzle: Function: Holds the firing barrel in place, while being a cosmetically pleasing exterior to the gun. Materials Used: Plastic. Manufacturing Process: Injection Molding.
10	Outermost Casing: Function: Holds inner components together. The vibrant orange color provides a drastic contrast to the average environment, which disallows misinterpretation between real weapons. Materials Used: Plastic Manufacturing Process: Injection Molding
11	Stock: Function: Intended for additional user modifications available at your local Nerf retailer. Materials Used: Plastic Manufacturing Process: Injection Molding
12	Firing Chamber: Function: The end guides the the firing spring into the center of the chamber, which ejects the dart into barrel. Materials Used: Plastic. Manufacturing Process: Injection Molding.
13	Firing Spring: Function: Is the main source of potential and kinetic energy for the firing of the dart. The compression and release of the spring is what firing the dart. Materials Used: Stainless Steel. Manufacturing Process: Forming.
14	Holding Bracket: Function: Holds firing chamber in place. Position may vary with subtle differences. Materials Used: Plastic and Stainless Steel. Manufacturing Process: Plastic- Injection Molding. Stainless Steel- Forming
15	Trigger: Function: It releases the firing spring, which allows for the dart to be fired. The user can pull the trigger as fast as he/she can cock the gun Materials Used: Plastic. Manufacturing Process: Injection Molding.
16	Cocking Arm Pushrod: Function: Connects the Cocking Arm Foregrip and the Firing Chamber. It allows for the gun to be cocked and a dart loaded into the firing chamber. Materials Used: Plastic and Stainless Steel. Manufacturing Process: Plastic- Injection Molding. Stainless Steel- Forming.
17	Cocking Arm Foregrip: Function: Allows the user to pull back the cocking arm foregrip. Also provides the user with stability when firing the gun. Materials Used: Plastic. Manufacturing Process: Injection Molding.
18	Drum-Magazine Holder: Function: Connects the Drum Magazine and outermost casing. It provides an easy release of the Magazine for an easy reload. Materials Used: Plastic. Manufacturing Process: Injection Molding.
