Project | 03: Make a model engine rod
This is project 3 of 11 in the model engine project series.
Make the next part of the engine assembly by modeling, programming, and machining a rod.
Overview
Sample process plans, setup sheets, cutting data, and inspection reports are provided but use your judgment, the tools, and machines you have available, and your knowledge to complete the project.
Project scenario:
A customer has asked your company to redesign a model engine assembly and to machine a prototype. They have provided engineering drawings of the original parts. This project requires you to model and redesign the rod while maintaining the length between bores and overall thickness. Use the engineering drawing as a reference for the bore sizes, spacing, and thickness. Consider various stock sizes and shapes to incorporate your unique design.
This project also requires you to set up and program toolpaths for the rod provided. Begin with the supplied engineering drawing and the CAD model. Use the engineering drawing as a reference to plan tools required and work out any work holding requirements. Consider various stock sizes and shapes and think about the number of operations required to machine the part.
The rod requires the use of a soft jaw, which is supplied. To find your soft jaw dimensions, you can use the supplied engineering drawing or source a soft jaw model that matches the soft jaws used in your shop. For more details on designing soft jaws, refer to Model engine project 2: Rod soft jaw. Sample process plans, setup sheets, cutting data, and inspection reports are provided but use your judgment, the tools, and machines you have available, and your knowledge to complete the project.
