Ryan Bierl Mae377 Project01

  1. 1. UNIVERSITY AT BUFFALO Project 01 Solid Modeling Assignment 01 Ryan R. Bierl 9/17/2009 Project 01 was intended to introduce Pro Engineer. To do this we were required to create three parts using the Tutorial and Multimedia CD. We learned the basic techniques in solid modeling, as well as various techniques in the “sketcher mode”.

Pro Engineer is a very widely used program within the engineering community as well as other industries. That is why it is important to understand how to use this program effectively. With the aid of the Tutorial and Multimedia CD we were able to learn the basic skills to create and manage models in the Pro Engineer program. 2 Project Requirements Project 00 is an introduction to 3D solid modeling. This project required the use of the Tutorial to create three vastly different parts using the various tools in Pro Engineer. 3 Results 3.1 Part A (a) (b) Figure 1 (a) The CAD model of the block in Part A; and (b) the same CAD model of Part A at a different view. 2

As you can see by viewing the above figure, the round and chamfer tools were used along with the hole tool. But before those tools were used the extrusion tool was implemented to give a 2D sketch depth. This tool is probably the easiest and most effective tools in Pro Engineer, at least at this level. The second part of Project 00 required the use of some more advanced tools in Pro Engineer. To create the shaft like protrusion at the top of the base you were required to create a revolved sketch along with 3

The first time we tried to create the protrusion it was centered on the back face instead of in the center of the top. To fix this were had to change the orientation of the first extrusion which was used to make the base of the part. Another feature that was used after removing the material from the base to create the cut-out, you were required to mirror that same cut-out. The purpose of mirroring an action it to decrease the amount of time spent on creating a model. The hole, chamfer and extrusion tools were also used to create this part. Even though Part C looks very complex, it did not require a lot of skill to create. The main feature, the fins, was created using a simple process called a pattern. Once one fin was created, you are able to select it and recreate it as many times as you desire. One of the biggest problems was that when we went to duplicate the single fin by making the pattern it would not recreate the fin with the desired thickness. This made it impossible for the revolved cut to affect the newly created fins. To rectify this we were forced to change the thickness for each of the 11 newly created fins and then reapply the revolved cut. Other than that Part C was relatively easy. 5 Conclusion The goals of Project 00 were to introduce Pro Engineer and its abilities for 3D solid modeling. I believe that these goals were accomplished, and that I have learned to use many of the tools that Pro Engineer has to offer. Also I believe that I have created these parts accurately . 6 References The references used to complete Project 00 are: Pro Engineer Wildfire 4.0: Tutorial and Multimedia CD written by Roger Toogood, PH.D., P.
