The core concepts of Mechanical Design analysis are the Degree of Freedom (DoF), Typs of Gear, Energy conversion, Gear force transmission etc. DoF of a mechanical system is the number of independent parameters that define its configuration. There are many examples of 6 types of DoF of both Translation & Rotation around us for exploring. We can also find the three basic types of gear such as Helical, Bevel, Rack & pinion in , & respectively. So the importance and applications of mechanical design analysis is everywhere.
I built prototypes using cork sheet and toothpicks to create different DoFs and apply it in a simple mechanical structure. The rapid prototype building is a skill which helps a lot to actually visualize our ideas. Building a prototype also ensures the final physical structure, stability and the approximations about the project. It helps to make necessary changes in the planning before it’s too late.
I also made OpenSCAD project which is basically an example of CSG tree (Constructive Solid Geometry Tree) generation. There are multiple cubes, cylinder and spheres. I applied difference(), translate(), rotate(), linear_extrude() etc functions. Then the code has to be compiled and built.
Then the .scad project has to be rendered with CGA ( Color Graphics Adapter).
Then for 3D printing, the project has to be exported as a .STL (STereoLithography) file format.
