The development of advanced machining processes is typically motivated by the need to improve the productivity and the efficiency. But there are also increasing demands on machining operations as a result of the use of high strength materials for new products. For the analysis and the design of optimized machining processes many aspects with respect to cutting tools, workpieces and process conditions as well as their interdependencies have to be considered. The presentation will give detailed information on a high performance tapping process, on the reduction of the straightness deviation in deep hole drilling with minimum quantity lubrication and on the development of suitable cutting tools and process conditions for tunring and deep hole drilling of high strength bainitic steels.
