CAD/CAM Midterm Project Report
Project Goals The goal of this project was to help students become familiar with a program created by the company Siemens called NX, specifically versions 8.0 and 8.5. Somewhat similar to the program SolidWORKS, NX allows the user to create sketches of simple and complex objects, and then create a 3-D model of the object. Also, an assembly of these models can be made by assigning constraints to create an overall 3-D assembly model. This project was made to utilize NX in order to create an assembly model of a skateboard, made of 6 different parts: The Bearing, The Board, The Bushing, The Connection, The Shaft, and The Wheel. Some parts were easier than others, such as the Shaft, which just required a sketch of a circle to be extruded to a certain length. Others required much more commands, such as the Connection and the Bearing, which required a sweep and many other constraints. Before the project was assigned, students were given many homework assignments that required them to create a part using NX, which didn’t require many commands. Over time, these assignments became more and more challenging, requiring more and more commands. After these parts were modeled, students were taught how to create an assembly using the parts modeled, which use constraints to keep them together such as Concentric, Touch Align, and Center. In order to model the 6 parts of the Skateboard Assembly, students were given IGS files as a reference. These files allowed students to open them in NX and use the Drafting environment to infer dimensions to recreate the part on their own. Dimensions in the sketches were the most important, especially when putting the board together, as dimensions that were not proportional to one another could cause an error in the assembly environment when assigning constraints.
