816005673 Final Year Project Logbook

 ENTRY #26 Today I attended the schools' workshop to proceed with the construction of my prototype .The first w work order was obtained by the Chief Technician Mr.Maxwell and construction with the help of my supervisor Imram Mohammed.  Construction began with the cutting of raw materials to length and grinding away any burs or debris remaining from the cutting process.  Afterward, the main framing was done by assembling the material according to the drawing dimensions. This was then tacked and welded into place however on completion of the main construction we discovered a flaw in the design where the legs were unstable. This was easily fixed by adding "Straps" or supportive material to keep the legs straight and rigid during operation.  The images below show the completed construction of the frame the next step is to update my Supervisor Mr.Ohja and schedule a meeting. This was done on Friday the 25th of February. 

 ENTRY #25  A meeting was conducted today from 11 am which lasted approximately 15minutes. I updated him on what occurred last meeting with my technician on Tuesday the 8th.  This meeting was only intended to keep updated with my Supervisor as communication is key between student and lecturer to ensure what must be done, is done appropriately.  He urged me to begin my analysis and instead of sending large documents which would be harder for him to "proof" read, I should instead send sections at a time to ensure the best I can. 

 ENTRY #24  Today a meeting was finally conducted with my assigned technician Mr.Imran Mohammed. We discussed the following topics :  - General Function and workings of the machine  - Materials that are already readily available in the workshop  -Bearings change due to the availability of the bearing previous. Essentially we changed the thrust bearings used for shaft 2 from regular thrust bearings to a Surface-mounted bearing. This will also increase the rigidity of the overall system.  - Selection of motor: From previous calculations, we have determined that a 1-2hp motor would be enough to have the rotational speed and torque for the operation of all tools. Whiles in the workshop today we determined that a 1.5hp, 1750rpm maximum motor would be ideal as it is small in size and capable of variable speeds.  The images below are basic dimensions and Nameplate fo the selected motor : -Further discussion of the Materials that might be changed was dine conc...
