ABSTRACT:
A tool in the form of a honeycomb cutter/chip breaker assembly for conveniently and efficiently machining a workpiece of honeycombed material or the like. The assembly includes a honeycomb cutter member having a cutting knife and a shaft. The cutting knife is disc-shaped with a sharp peripheral edge and is formed integrally with the outboard end of the shaft for concurrent rotation therewith. The inboard end of the shaft is adapted to be received by rotational motion imparting mechanisms. The assembly also includes a chip breaker/chaf remover device having a central bore mountable over the shaft with its outboard face in contact with the inboard face of the cutting knife for rotation therewith during operation and use. The radially outward edges of the chip breaker/chaf remover device are formed as sharp breaker edges for breaking the material cut by the cutting knife. Radially inward of the breaker edges of the device are essentially semicircular surfaces for the removing of the broken or chaf material from adjacent the workpiece. The cutting knife first cuts the workpiece and the cut portions or chips of the workpiece are then broken and then the broken chaf removed, all continuously and simultaneously, without the need for stopping the operation of the tool.
