Model engine project 10: Cylinder flange
Apply your skills in this module by making a cylinder head, which is a part of the model engine assembly.
Use your judgement, knowledge, the tools, and machines you have available to set up and program toolpaths for the cylinder flange provided.
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. They would like all the internal parts to be interchangeable but would want the exterior design of the engine to be unique. This project requires you to model and redesign the cylinder flange while maintaining the mounting locations to the cylinder as well as internal feature sizes for the intake and exhaust. engineering drawing. Use the engineering drawing as a reference for the mounting locations and overall dimensions of the part. The part has symmetry about the center location. Consider various stock sizes and shapes to incorporate your unique design and consider any changes to the outside shape should be considered how they interface with the cylinder component as well.
The customer also asked your company to prototype the cylinder flange. They have provided engineering drawings of the original part as well as a neutral CAD model of the cylinder flange. This project requires you to set up and program toolpaths for the cylinder flange provided. Begin with the supplied engineering drawing. Use the engineering drawing as a reference to plan tools required and work out any work holding requirements.
The cylinder requires the use of a soft jaw which is supplied. For more details on designing soft jaws, please refer to Model engine project 9: Cylinder flange soft jaw. Consider various stock sizes and shapes and think about the number of operations required to machine the part. 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.
Teaching this project to students in the classroom?
Use this instructor guide to incorporate this and our other model engine projects into your lesson plans. You'll understand how to use CAD and CAM workflows to combine this and other projects into a model engine assembly. Then, machine the model engine using standard stock sizes.
