Model engine project 1: Cylinder

Using the model and engineering drawings provided, set up and program toolpaths for the cylinder.

Project scenario:
A customer has asked your company to redesign a model engine assembly and to machine a prototype. The company has provided engineering drawings of the original model engine cylinder as well as a CAD model of the part. This project requires you to model and redesign the cylinder while maintaining critical features like the standard bore, bolt spacing, locating pin locations and side ports. 

You are also asked to create a prototype requiring you to set up and program toolpaths for the cylinder provided. 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.
