  1. 1. ANTHONY BAILEY JR. UC Berkeley Mechanical Engineering Student, Senior *Self-made CAD of a Seabotics Thruster in Autodesk Inventor* Phone: (310)-780-6008 Email: abaileyjr2016@gmail.com
  2. 2. MOOG Aircraft Group *The following pictures & pieces are neither my property nor have I have designed due to NDA, but are representative of my work* Manufacturing Engineering Intern in both commercial and military sectors o Conducted an investigation (SPC) to determine at what process in its production a family of parts was not meeting dimensional tolerances. With the collected data determined an appropriate solution. o Then proceeded to be exposed to and help conduct a Design of Experiments (DOE) by determining testable factors, working with shop managers to arrange tests, and taking measurements as test runs were completed. o Designed a point-of-use storage system using shadow-boards, in cabinets similar to what is shown, to increase operator effeciency as well as protect company property. Systems were created for tooling for various machine spindles as well as for inspection equipment.
  3. 3. L-3 Communications *The following pictures & pieces are neither my property nor have I have designed due to NDA, but are representative of my work* XIPS (Xenon Ion Propulsion System) - Summer 2014 Internship with L-3 communications ETI division in Torrance, CA. During this internship I worked on various internal subsystems within their 25cm class XIPS module. - Work encompassed the use of the Creo Parametric 2.0 modeling software for the creation of new designs and drawings as well as the ANSYS thermal environment suite for testing of such designs for the extreme environments involved in orbital travel.
  4. 4. Project Coursework ME 130 – Design of Planar Machinery -Pictured below is the final product of the Smash Chop, an automated fruit chopping device created in UC Berkeley’s ME 130 class. In the class we were tasked to create a device which would be able to utilize planar machinery to complete some task under its own power. -The device was manufactured in house with nearly all components made by the project group. Pictured below is the raw stock I formed by water jet process for the various pieces needed in the machine. The design was a cylindrical chopper utilizing a circular grid of blades that were also made by water jet process. The project came together quite well and was able to cut various fruits as initially designed. -Materials utilized in this project ranged from 304 Stainless Steel for the grid of knives to 1/16” cold roll steel for the larger structural strips to be rolled into the frame components. The device manufacturing and design was done on Solidworks with all modeling done by myself. Manufacturing of metal materials was handled by myself. The project taught me time management as well as the necessary skills needed to be able to produce fully functional prototype of a product.
  5. 5. Project Coursework ME 122 – Processing of Materials in Manufacturing -Pictured below is a CAD model of the Motorized Pot Rack device created in UC Berkeley’s ME122 class. In this class, teams were tasked to come up with a marketable device, modeling some of its features, and then focus heavily on the selecting appropriate materials selection and manufacturing process selection. - In this project I modeled up various components and then proceeded to go through the necessary steps to choose an appropriate material and manufacturing process for all non-OTS parts in the component. In the pictures below is shown the CAD assembly and an example of the material’s selection diagrams used help decide which materials would be appropriate for a part given a beforehand analysis of what forces and moments it would be expected to receive.

  6. 6. 3D Modeling & Drawings CAMS Engineering Development and Design Project 2012 - 3D model created in the Autodesk Inventor environment for the capstone engineering course. - Device is a repair robot design to drive over various obstacles while using its high torque arm to attach to a downed robot then lift itself and provide power and comms. CAMS ROV Team, MATE Challenge - Conceptualization, Designing, and then manufacturing of a controllable waterproof vehicle for completing various tasks ranging from driver to control to object manipulation. - Proper engineering drawings and design for manufacturability were vital during the project, as well as constant iteration.
  7. 7. Pioneers in Engineering (PiE) - The drawing and render below both represent a single component of the library of CAD files and engineering drawings done throughout the operation season in PiE - The picture on the left is of a “universal hub”, a fastener that is used in the transfer of rotational motion from a shaft to that of another object via the screw holes on the large face. The “universal hub” rotates via set screw friction. Various iterations of the design have been made over a span of varying aluminum and steel alloys until this final product. Thought was put into the manufacturability of the piece, as it was designed to be mass produced with many on a long bar then cut out at a later stage. - The drawing above is the compliment to the 3D CAD above. This drawing sheet, utilizes modern drawing techniques to convey to the machinist exactly what is to be made and how it is to be made. It is a combination of engineering drawing and manufacturing guide. It represents the style I wish to seek with my engineering, one that knows what it takes to also make it, and thus is easier for end users to handle.
  8. 8. Research/Matlab Summer 2013 Research Assistant. - Poster created for the end of my term as student research assistant for the summer of 2013. During the summer I conducted experiments and performed data analysis on a VF-0 CNC HAAS mill to determine the power efficiency of climb vs. conventional milling of various tool paths. I was tasked to find some means of detecting trends in the raw data received from the machine and of sorting it into useful data. To do this the Matlab script on the left was created.
  9. 9. Machine Shop Experience Pioneers in Engineering -One of many machining jigs produced while in PiE, this picture on the left is of a clamp jig to hold a cabochon (hemisphere) of acrylic to be machined for use as an LED diffuser. The Jig was made of left over HDPE stock in the Berkeley Shop, custom made to attach to the Kurt vise on the Bridgeport mills. - Through the shop at Berkeley I gained the experience and the knowledge to be able to not only design my own devices, but to effective consider the cycle as a whole. To be able to consider how to actually approach manufacturing the various products and designs and the go ahead and make them for myself. - I have also refined my abilities in the use of manual and CNC machines. This set of metal on the left is two bars in one jig with a CNC code written and uploaded to mill out the whole pattern. Through the PiE production environment I have honed my skills as a machinist, and can figure out how to practically approach making things. This in turn helps me better understand and catch errors in designs and concepts.
