Study on the Influence of Geometrical Parameters of Abrasive Grains in Abrasive Flow Machining
In order to improve the accuracy of quantitative calculation of abrasive flow machining, the influence of geometrical parameters of abrasive grains on machining is analyzed by representing the geometrical shapes of abrasive grains with three parameters, namely height of abrasive grains, cone angle and wear height, establishing the calculation model of blunt conical abrasive grains for abrasive flow machining, deducing the force formulas of abrasive grains and calculating the maximum cutting depth in the event of smooth flow of abrasive grains in the boundary layer. It is shown by researches that the geometrical parameters of abrasive grains have significant influence on the maximum cutting depth as follows: The maximum cutting depth of abrasive grains increases linearly with the increase of height of abrasive grains, and varies in the form of hump with the changes of cone angle, the cutting depth has the maximum value when the cone angle reaches 60°; The maximum cutting depth of abrasive grains decreases rapidly with the increases of wear height, when the wear height increases to a critical value, the abrasive grains basically lose cutting ability.
