Abstract: Cryogenic cutting of hard stone, a new method for cutting hard stone such as marble and granite, is proposed. By jetting the cryogenic fluid on the cutting area to form the local cryogenic cutting area, the cutting efficiency and tool life are improved. The experimental results show that with the help of the method, the tool life can increase many times by comparision with conventional outing method, and the environmental pollution can be greatly improved.
