一、磨削过程的物理模型 在金属磨削过程中,摩擦起着极为重要的作用。分析摩擦时,不仅要考虑到摩擦系数的常规物理特征,而且要注意到摩擦系数受下列因素影响:相互接触表面的性质,接触表面的冶金、化学等方面的性能,接触温度,载荷类型,应变速度,冷却润滑液等。 普兰德曾对圆冲头 First, the physical model of the grinding process In the metal grinding process, friction plays a very important role. In analyzing friction, not only the conventional physical characteristics of the friction coefficient should be taken into consideration, but it is to be noted that the friction coefficient is influenced by the properties of the mutual contact surfaces, metallurgy and chemical properties of the contact surfaces, contact temperature, load type, strain Speed, cooling lubricant and so on.
