Removal of Stainless Steel Burrs by Ultra-low Temperature Ice Jet Blasting

The presence of burrs in the machining process directly affects the accuracy of the machined part. As the machining industry demands higher precision in its products, the necessity for effective burr removal has become increasingly crucial. Developing efficient and environmentally friendly burr removal techniques to guarantee the surface processing quality of the parts is still a challenge. The ice jet deburring process represents a green and clean processing method. Its fundamental environmental benefit is based on its green attributes, which span the entire process from the source to the waste treatment. This paper combined the simulation and verification tests to study the deburring mechanism of the ice jet. The ANSYS was employed to simulate the velocity distribution of the sprayed ice particles to ascertain the optimal jet distance. The ABAQUS was utilized to develop a kinetic model of the ice particles impacting on the metal substrate to determine the optimal test parameter range. Based on the above simulation results, experiments on removing burrs from stainless steel using ice jets were carried out, and the optimal combination of the processing parameters was determined. Eventually, the height of the burrs could be reduced to 0.05 mm without an obvious change in the surface roughness. Concurrently, the simulation and experiment results were analyzed to investigate the acceleration of the ice particles in the pipeline and the extent of the impact of ice particles on the burrs, thereby further clarifying the removal mechanism of the stainless steel burr.
