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. | 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.

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.
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.
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:
• Request for Proposal – 10/9/09
• Preliminary Project Review – 10/30/09
• Coordination Review – 11/23/09
• Critical Project Review – 12/7/09*each stage has additional sub-tasks: see Diagram 1 for the complete Gantt chart
Executive Summary
The Black & Decker® DR202 3/8” Variable Speed/Reversible Drill is a must-have tool for almost any project. This six-pound power tool is light enough to be used for the everyday 'do it yourself' tasks while the five-amp motor is powerful enough for professional carpentry and construction jobs.
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.
