AI Technical Summary

Problems solved by technology

Spraying abrasive solutions is problematic as it can result in removal of microscopic features of material and / or melting of material
Conventional cryogenic cooling techniques suffer from the same overcooling problems associated with cryogenic cooling during machining

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 (1 14) to harden the burrs (134a), then brushing the material (1 14) to remove the hardened burrs (143a).

Description

[0001] 【CROSS-REFERENCE TO RELATED APPLICATIONS】 [0002] This application claims the benefit of U.S. Provisional Application No. 60 / 994,787, filed September 21, 2007, and U.S. Provisional Application No. 61 / 012,653, filed December 10, 2007, both of which are incorporated by reference as if set forth in their entirety incorporated in this article. [0003] PCT International Application No. PCT / US08 / 074506 filed August 27, 2008 is incorporated herein by reference as if set forth in its entirety. 【Technical field】 [0004] The present invention relates to an apparatus and method for mechanically processing polymers using controlled cryogenic cooling. 【Background technique】 [0005] The use of polymeric materials is increasingly accepted in the biomedical industry. Many polymer parts (referred to herein as "biopolymers") for biomedical products are produced in small and medium-scale batches. Thus, mechanical processing of biopolymers represents a cost-effective alternative t...
