Abstract
A method and apparatus for discharging a temperature-controlled flow of a resultant fluid (32) containing a throttling gas and cryogenic fluid onto a material (14) for the purpose of maintaining the temperature of the material within a desired temperature range and below the glass transition temperature of the material during machining. Also disclosed is an apparatus and method for deburring or deflashing a machined material by discharging a temperature-controlled flow of a resultant fluid (132) onto a machined material (114) to harden the burrs (134a), then brushing the material (114) to remove the hardened burrs (143a).
