A three axis CNC router design

A preliminary design of a low-cost, three-axis, computer numerically controlled (CNC) router was completed with the goal of bringing the advantages of numerically controlled machine tools to the woodshop. To reduce cost, a novel single rail design was employed. The number of custom parts was kept to a minimum and, where necessary, every effort was made to minimize manufacturing cost. The novel features of the design include vacuum clamping, the ability to cut joinery at miter angles from 0* to 90*, and force controlled cutting. Many of the components are used quite aggressively (particularly with regard to stiffness), but the accuracy goal of ±0.005 " in X and Y and +0.010" in Z was met.
