Design and manufacture of a CNC desktop lathe for use in a project-based class

The objective of this project is to evolve the design of a CNC desktop lathe for use in a project-based class and then fabricate a prototype to confirm the functionality of the design. This iteration of the lathe effectively reduces the cost, size, weight, and complexity of the machine to make the lathe more accessible and robust for use in as a learning tool. Elements from previous lathes are integrated into the new design along with other improvements. The original 14"x20" footprint is reduced to 9.5"x15" by reconfiguring the actuators and integrating the spindle motor into the headstock. Redesigning the lead screw bearing configuration reduces the part count and complexity. Hard stops are added to the lead screw flexure to make it easier to handle during assembly. A bellow chip cover is added to keep the lathe cleaner during use.
