Abstract: In non-abrasive cryogenic polishing, ice disk is used as polishing tool .The effects of ice disk characteristics by different water quality on surface roughness of machined parts are investigated. Non-abrasive cryogenic polishing is a plastic transfiguration process based on brittle-plastic transition theory. During machining, higher micro peaks become lower and the number of micro peaks increases which results in lower roughness. Experiments are done to attest to the process.
