Study on heat transfer in super-high-speed grinding: energy partition to the workpiece in HEDG

Based on an analytical thermal model for deep grinding, in which the effect of the inclined angle ϕ of the heat source plane to its moving direction is taken into account, the relations of workpiece energy partition ε to relevant grinding parameters are obtained. It is suggested that the inclined angle ϕ, grinding speed and also work feed all have strong influences on the energy partition to the workpiece. From the viewpoint of reducing the value ε, a higher grinding speed, lower feed speed, relatively shallow cut and larger wheel size should be selected.
