Francis Turbine has many components which are manufactured in different ways. One of its parts, guide vane, is manufactured by using investment casting technology. <br /> <br /> <br /> Investment casting process requires positive pattern which is made of wax material. This pattern, called wax pattern, is produced by injection process which requires a metal mold. The mold cavity is manufactured by three axis numerical controlled milling machine. <br /> <br /> <br /> This final project focuses on the manufacturing of the wax mold cavity by the assistance of CAD/CAM system. The author used Delcam PowerMill and Delcam PowerShape software, thus created NC program as the output of this project. Operation of the NC machine is not discussed here. The creation of NC program is based on the optimum cutting condition, which <br /> <br /> <br /> calculations are being held by a systematic approach. The author hopes that this writing will be a comprehensive guide to the right way of the cutting plan of wax mold cavity using NC machine.
