  1. MEC1011 Fall’03 Assignment 6 Due at the end of Week 4 Reference Lessons 9 & 10 and complete the following. • PART 1 • Sheet metal consruction. • Make a .ipj (project file and folder) in V:/MEC/1011/Assignment 6/TxA • Using the Sheet Metal.ipt you must deliver a flat pattern of an electrical box. (see samples at front) To swap from “model to sheet metal” feature toolbars use applications from the menu drop downs) • You will need to create a new punch to make the thru holes on the sides and bottoms. • To make the new punch you will use the iFeature command. • Start a new drawing • Make an extruded plate to set the punch. • For the 2nd feature make the shape of the punch. Make the OD 1” and the slit .02. Leave a tab connecting the round to the first extrusion. Be sure to place a point/hole center in the middle of the punch shape. • Using TOOLS/Extract iFeature select the 2nd feature. • Move the 2 parameters of OD and Slit Thickness to the right and rename the Parameters to OD and Slit. • Save the new punch to your folder. • Reopen your sheet metal part and using the punch feature place the punch outs in your box, using point/hole center. • As you insert the punch you will have the opportunity to modify the sizes to be in proportion with your box. • Design a cover to fit your box. • Assemble the 2 parts using a new .iam. • NB. The sizes are not critical but the visual proportions should approximate the samples.

  2. PART 2 • Construction of a solid model of the paperweight concept drawing. • Take your concept sketch and model it in Inventor. ( .ipt File type) • After you have created the solid model you will document the model. • Open a new .idw. This is the file that handles the orthographic projections and dimensioning. • Place the base view of your Paperweight in the .idw and then project the other 2 views and an isometric view. • Place dimensions and tolerances on the paperweight that will control sizing and geometric characteristics. • Use Datum References for the X,Y,and/or Z planes. Indicate perpendicularity, flatness and parallelism, using geometric tolerancing. • Hand in a print of the .idw at a 1:1 scale.
