Abstract
Recent Change in the machine tools is discussed in this paper, especially the machining centers with high speed, high acceleration rate and intelligence. High speed machining centers with feed rate of 60 m/min, acceleration rate of 1G and spindle speed of 20,000/min are becoming very popular in the area of aluminum alloys machining. These machining centers have been developed for improving productivity, and will be used for agile and high-volume FMSs. These machining centers are very effective for die/mold making. The remained problems for these machining centers have been discussed. The intelligent machine tools is one of the key technologies which can realize these problems.
