Abrasive Grain Association的用法和样例：
- If the undeformed chip thickness is reduced, the effect of the top part of the abrasive grain will increase.
- The bond is mainly intenbed for hording the abrasive grain together so that the bonded wheels have got definite shapes and necessary strength.
- Under the condition of boundary lubrication,adhere wear mechanism and abrasive grain wear mechanism do the business at the same time.
- The first principal normal stresses can lead to grinding crack which generates behind the abrasive grain in the plane perpendicular to grain motion.
- For the effects of test conditions, the volume wear value increased with the sliding velocity and the abrasive grain size except for the sliding velocity of 1.68 m/s and 3.02 m/s.
