REDUCE PROCESS CHAINS DUE TO THE PRECISION FORGING OF GEARS-EFFECT ONTHE CONVENTIONAL FORGING TECHNOLOGY

In the past, the range of parts of hot massive forming could, as a res ult of the technologically induced production tolerances, only seldom be extended to include workpieces with higher demands on accuracy. Due to a comprehensive cooperation between research and industry. the tec hnology of precision forming, however, becomes more and more important in comparison with metal-cutting soft machining processes, as this te chnology may, with the same production accuracy and productivity, redu ce the production costs. In the field of precision forming, the produc tion of gearings takes on a main position due to the great market pote ntial of geared parts. If the development of forming processes for the mass production of gears is successful, these may substitute machinin g which has up to now been predominant in this field.
