Particle Flow Simulation on Semi-Fixed Abrasive Tool Processing
The semi-fixed abrasive tool (SFAT) is a new tool used in the ultra-precision machining. Based on the theory of particle flow code (PFC), the abrasive particle motion characteristics of SFAT are studied in SFAT processing which is divided to workpiece pressing progress and workpiece tangential moving progress. It is conclusion that the particles are fallen out the tool surface due to the fracture of bonds under the normal force of workpiece point in the workpiece pressing progress; the particles contacting the workpiece are moved on every hand while some particles fall out the surface at the edge of abrasive tool in the workpiece tangential moving progress, and the maximum value of binding agent holding force is computed.
