Model Establishment of Chip-Formation due to Shock under Ultra-High Speed Grinding
The theory model of the indent experiment of the brittle material was established, its specific energy was analyzed, and the calculation expression of the total specific energy for a single grain was given. Experiment process and results were given. Ultra-high speed grinding experiment was done, and its results were obtained. After the results were analyzed, the conclusions were gained that brittle materials could produce ductile-regime grinding under ultra-high speed shock. The model of mechanism of chip-formation due to shock in quasi-fluid phase on super-high speed grinding was established, and the chip formation hypothesis for the chip formation mechanism on ultra high speed grinding was produced.
