Development of Ultra High Speed Milling Machine using Reciprocating Layer Cutter Path

To realize highly efficient high speed milling of curved surfaces, it is important to resolve problems such as the generation of NC data, and the design of machine tools which will keep up with the new requirements. The reciprocating layer cutting path method serves as one solution to these problems. The aim of this study was to prototype a novel high speed milling machine. With an air bearing spindle, rotational speed of more than 100000 min^-1 are realized. By providing a U axis against the X axis, feed speed of 100 m/min and acceleration speed of 2 G is possible. Milling experiments are carried out to clarify the advantages of the method.
