Abstract: In order to realize high speed machining, the special
requirements for feed transmission system of the CNC machine
tool have to be satisfied . A high velocity feed unit driven by
a induction linear motor is developed. The compositions of the
high velocity CNC feed unit and main problems in the unit design
are discussed.
Key words: High
speed machining Machine tool Feed system Linear motor
