Automating Grinding Setups For Root Form Tools

Root form slots found in turbine rotors are characterized by complex contours and precise dimensions. “Christmas tree” form tools used to cut those intricate slots must be precisely ground so no portion of their profile pushes through their tight tolerance band. Consequently, setting up grinding machines to repeatedly deliver quality root form tools is often challenging and time-consuming. MORE
