Grinding Force Model for Low-speed Grinding Based on Impact Principle
In the low-speed grinding process,the force generated when the wheel grinding the workpiece is the result of sliding fi-iction,plough and cutting.While in the actual study,the cutting process has attracted extensive attention.Impact effect to the entire grinding process on the contact is ignored so that the error exists between the calculation grinding force and the measured grinding force.Basing on the shock effect to the grinding process,the paper divides the contact area into impact area and cutting area.And the model of impact load generated from single grit is built.Moreover,the grinding force theoretical calculation model and total grinding force mathematical model is also constructed by analyzing the impact load affecting on the grinding force mechanism.Finally experimental study verifies the correctness of theoretical analysis.
