Stage 3.Manufacturing Plan (Week 8) Develop manufacturing plans for your design.This includes full dimensioned and toleranced engineering drawings on Unigraphics(or another CAD package with permission of instructor).You should have a build plan with an ordered list of machine steps with speeds.This will be reguired before permission is given to begin building.In addition,an assembly drawing of how all the pieces will be put together should be sketched out. Deliverable:At the end of this task you should have a CAD drawing and build plan for each component you will be making along with a simple assembling drawing.This will be required before permission is given to begin building Stage 4.Build and Test (Week 9-15) Build your prototype using the material ordered (see below)and the machine shops.Work in the machine shop cannot begin until each group member has completed the required training on the Lathe and Milling machine (assuming each member completed the cutting/drilling training in ME 250. The power supplies will be made available during this period for trial tests. All machines will be tested on Wednesday-each team given a designated testing time. Since we do not want to take all of Wednesday it is important to have the set-up and take down be as quick as possible.You will be given only 2 minutes to set up and two minutes to take down.If you go over this time you will lose 5 points per each minute over.When designing your prototype,do not forget that it will need to be portable for set-up and takedown. You will be given one formal trial during which the overall time from turning on the switch to the machine stopping in the original state.If you do not succeed,you will be given an additional trial(s)at the discretion of the instructor and you will be given a 5-point penalty per trial.A 3 point penalty will be assessed for any machine not returning to its original state and stopping.The parts available for this project are as follows:Stage 3.
