Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional aqueous abrasive jets are used, then the cutting process can be performed, but the process cannot be continued continuously due to abrasive accumulation
Solution Approach 1:
The patent implements a recycling system that recovers abrasive particles from the spent aqueous abrasive jet mixture. The abrasive particles are separated from the water, dried, and reused in the cutting process, thereby eliminating the need to discard abrasive material and enabling continuous operation without interruption for abrasive replacement or container cleaning.
Solution Approach 2:
The patent extracts and removes the abrasive particles from the spent aqueous abrasive jet mixture using separation devices such as cyclones, centrifuges, or filters. This extraction allows the abrasive particles to be recovered and reused, while the water can be recycled or disposed of, thereby enabling continuous processing without abrasive accumulation issues.
2Productivity
If conventional abrasive containers with cornered bottom contours are used, then the container structure is simple, but abrasive particles accumulate at the corners causing process interruptions
Solution Approach 1:
The patent modifies the container bottom contour from traditional cornered designs to a curved or spherical shape. This curvature eliminates corners where abrasive particles could accumulate, allowing the abrasive mixture to flow smoothly and continuously from the container, thereby enabling uninterrupted cutting processes without additional complex drainage systems.

AI summary
The present disclosure provides a processing method of suspension abrasive jets, and the method comprises the following steps. Provide a workpiece on the processing machine. A suspension abrasive containing a plurality of abrasive particles with the same electrical property is provided in an abrasive suspension container. A non-aqueous fluid is supplied to the abrasive suspension container from a high pressure source. The workpiece is machined by jetting a suspension abrasive jet that couples a suspension abrasive and the non-aqueous fluid from a nozzle. The suspension abrasive and the non-aqueous fluid of the suspension abrasive jet are respectively recycled to the abrasive suspension container and the high pressure source by an abrasive separation and recycling device after the process.
