Model engine project 8: Cylinder head
Create a cylinder head, which is a part of the model engine assembly.
Overview
Using the model and engineering drawings provided, set up and program toolpaths for the cylinder head.
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. This project requires you to model and redesign the cylinder head while maintaining the mounting locations and pins to the cylinder as well as internal engine clearances with the piston. 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 piston center location. Consider various stock sizes and shapes to incorporate your unique design. Consider any changes to the outside shape and how they interface with the cylinder component. Changes to the piston in a previous project should be accounted for in the cylinder head design as well.
The customer also asked your company to prototype the cylinder head. They have provided engineering drawings of the original part as well as a neutral CAD model of the cylinder head. This project requires you to set up and program toolpaths for the cylinder head 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. 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.
