One major application of broaching is the production of internal gears for the automotive industry. Today, broaching with tools made of high speed steel is state of the art. However, because of the low hot hardness the cutting parameters are limited and process lubrication is mandatory. A promising alternative is the use of the carbon free cutting material MC 90 Intermet, which possesses a higher...
The substitution of wet machining processes by dry processes is an important development in manufacturing technology. A central challenge is the significant higher heating and thus the resulting thermal expansion of the workpiece which leads to geometrical deviations of the machined part. According to the state of the art these processes are optimized by trial and error approaches and therefore result...
