Grinding performance evaluation of porous composite-bonded CBN wheels for Inconel 718

For high-efficiency grinding of difficult-to-cut materials such as titanium and nickel alloys, a high porosity is expected and also a sufficient mechanical strength to satisfy the function.However, the porosity increase is a disadvantage to the mechanical strength. As a promising pore forming agent, alumina bubbles are firstly induced into the abrasive layer to fabricate porous cubic boron nitride（CBN） wheels. When the wheel porosity reaches 45%, the bending strength is still high up to 50 MPa with modified orderly pore distribution. A porous CBN wheel was fabricated with a total porosity around 30%. The grinding performance of the porous composite-bonded CBN wheel was evaluated in terms of specific force, specific grinding energy, and grinding temperature, which were better than those of the vitrified one under the same grinding conditions. Compared to the vitrified CBN wheel, clear straight cutting grooves and less chip adhesion are observed on the ground surface and there is also no extensive loading on the wheel surface after grinding.

缓磨时工件烧伤过程的计算机仿真研究

在关于缓磨时的磨削热、接触弧区换热过程以及工件表层非稳态温度场的深入研究的基础上构造了一个可用于计算工件表层温度场畸变历程的数学模型，并据此完成了缓磨时工件烧伤过程的计算机仿真研究。仿真结果与缓磨时的实际烧伤过程吻合良好。本文率先阐明了缓磨烧伤的热机理，并证实了缓磨烧伤是一典型的渐变过程，它有明显的前兆特征，因而是可以被预报和控制的。此项创造性工作可以被看作是对磨削基础理论的一项重要贡献。
