 The main purpose of the DR202 is to drive and remove screws, and drill holes through various materials such as dry wall, steel, soft and hard woods, and plastics.  It operates by taking electrical energy supplied by a standard household power outlet which it converts to rotational energy used within the motor.  The rotational energy is transferred to mechanical energy, moving the gears within the motor, which supplies the torque to move the bit. It has variable speed: the farther the trigger is depressed, the higher the speed of the drill.  The drill can also be locked for continuous use by squeezing the trigger while pushing in on the trigger lock mechanism.  Additionally, the drill has a 8’ electrical cord with a two-prong plug.  It has a direction reverse switch: push the switch to the right for forward rotation (clockwise rotation), push the switch to the left for reverse rotation (counterclockwise).  The drill has a fifteen-position keyless chuck and a convenient bit holder located on top of the drill.

		+	==Introduction==
		+	On September 25, group 1 was tasked by course MAE 277 (SUNY BUFFALO) to reverse engineer a Black & Decker® drill while paying specific attention to its various aspects of design and manufacturing. The purpose of this project is to reinforce group work skills, technical writing skills and introduce the design process in order to better prepare students for industry. <br><br>
		+	Tabulated data will be compiled using Microsoft Excel to create tables and charts, and Computer-Aided-Design to produce models of Black & Decker® drill components. The compiled information will be uploaded to the internet utilizing a design repository and will be in MediaWiki format.<br><br>
		+	The group has until December 11 to take a functional Black & Decker® drill and: disassemble/reassemble, upload data to MediaWiki, and perform a 6-minute presentation to the fall 2009 MAE 277 class. To ensure that the group stays on task and continues to make forward progress, a series of 4 stages has been established at which point certain criteria must be completed. The group has roughly two months to complete these four stages and their accompanying due dates are:<br>
		+	<blockquote>• Request for Proposal – 10/9/09 <br>
		+	• Preliminary Project Review – 10/30/09 <br>
		+	• Coordination Review – 11/23/09 <br>
		+	• Critical Project Review – 12/7/09

−	~~==Post-Reassembly Analysis==~~
−	~~Below are a few sample questions that address the final condition of the product, disassembly/reassembly differences and further product recommendations:<br><br>~~
−	~~<b>- Does your product run the same as it did before you disassembled it?</b>~~
−	<blockquote> The product runs the same as it did before the disassembly process. We attribute the successful disassembly and reassembly of the process to the detailed notes and photography making it easy to retrace the steps.</blockquote>

−	~~<b>- What were the differences between the disassembly/reassembly processes?</b>~~
−	<blockquote>The main differences between the disassembly and the reassembly processes were the attention to detail needed. For example, it's easy to remove all of the small washer, the heat sink, and the red washer, but when returning the armature to its original form, the person doing the reassembly needs to know the order and the orientation of the heat sink so that the product will fit in the drill housing properly. similarly, when combining the field and the reverse ring, there are many opprotunities for mistakes: wire placement and the proper orientation of the reverse ring on the field itself.
−	~~<BR>~~
−	~~<BR>~~
−	~~Taking good notes and paying close attention to each piece prior to removing it is allowed the group to reassemble the entire product.~~
−	~~<BR>~~
−	~~<BR>~~
−	~~<B>Different tools used:</b>~~
−	~~<blockquote>~~
−	~~Needle-nose pliers</blockquote></blockquote>~~
−	~~<b>- What additional recommendations would the group make at the product level</b>~~
−	<blockquote>The only area of the drill that the group felt could benefit from modification was the field and reverse ring. The first modification that could be made would be to implement a notch into the field and a protrusion on the reverse ring such that the two could only fit together one way. This would prevent the two from being reassemble improperly. The second modification would be to replace the current system of connecting the wires individually into the reverse ring with a single plug in system which would further reassmbly confussion.reduce faughlty reconstruction of the motor assembly
