Machining of Automobile Engine Cams Using Two Cutting Tools Controlled with Linear Servomotors 2001-01-0973
A machine tool with four-control axis for machining of engine cams is presented and built to improve a machining efficiency in this study. A workpiece is fixed at a spindle chuck and placed between two cutting tools on the machine tool. Positions of the cutting direction of two cutting tools are controlled independently with two linear servomotors set on a linear rail guide. The linear servomotors are controlled with a PC, various products with non-circular cross sections can be then machined by the machine tool. Machining experiments shows that the machine tool is effective to reduce machining time and improve machining accuracy.
