The high-speed machining as an advanced cutting technology has been increasingly used since the 1980s. The high-speed machining with cutting speed and feed rate is much higher than conventional processing, not only can improve processing efficiency, shorten the processing time, but can also obtain high machining accuracy. With the development of high-speed machining spindle, instead of supporting the new tool is emerging, high-speed machining tool process parameters optimization and the deepening of At present, Germany, USA, Japan and other industrialized countries on a world leader in research and application of high-speed processing technology, especially the early start of German high-speed processing, the results more. As early as1984, the German National Research Group (DFG) funded seven million marks funded the production technology and the Machine Tool Research Institute of the Industrial University of Darmstadt, Germany (of PTW, Institute of Engineering and Machine Tools),Production and 41 four-year cooperation, and comprehensively carry out the cutting mechanism of high-speed processing, high-speed processing technology, high-speed machining machine tool. The government attaches great importance to and vigorously funded research has yielded fruitful results. Germany, many companies quickly mastered the high-speed processing technology, and continue to support and promote in-depth research and development of the technology.
This article on PTW Research Institute in Germany in recent years in the high-speed machining tool process parameters optimization as an introduction to the latest research results and hope to provide a useful reference for research and application of the domestic high-speed processing.
Characteristics of two high-speed machining
High-speed machining (High Speed ??Cutting, referred to as HSC) is usually carried out under the conditions of 5 to 10 times higher than that of conventional processing speed machining. High-speed processing, according to the different processing materials, processing methods, process, tool parameters and consider tool life and machined surface quality to select the cutting speed.
