Abstract
Abrasive jet stream cutting, wherein an abrasive is suspended in a flowable jet medium (64) and projected at high velocity and pressure (75) at a workpiece (76) is substantially improved by forming the medium of a polymer having reformable sacrificial chemical bonds which are preferentially broken under high shear conditions. Projecting the medium and suspended abrasive breaks the reformable sacrificial chemical bonds while cutting. The chemical bonds will reform, permitting recycling of the medium and abrasive for reuse in the method. The jet is effective at pressures of about 14 to 80 MPa.
