Research on Measurement Thickness and Growth Behaviors of Oxide Layers in Pre-Dressing Process of ELID

Abstract

In order to measure thickness and Study on growth behaviors of oxide layers on grinding wheel surface in ELID, measurement system accuracy is verificated with laser and eddy current sensor for simulation measurement of oxide layers, Growth behaviour of oxide layers were measured in pre-dressing process, the results indicate inward growth speed of oxide layer is greater than outward growth speed along the radius of grinding wheel in the early , oxide layers keep linear growth and growth speed is the fastest; In the late ,inward growth speed of oxide layer slows, outward growth speed is slightly faster, but overall oxide layer growth slows down.
