Abstract:

The objectives of this research program were to develop machining techniques which could be used to grind a small, one piece gas turbine rotor out of a fully densified silicon nitride blank. Metal bonded diamond cup wheels and mounted points were used to drive abrasive slurries in accomplishing the machining. A few sample blades of fair quality were machined using the mounted point system, but the stock removal rate was found to be too low to be commercially feasible. Author
