Evaluation of Coated Abrasive Grain Geometry and Wear via Continuous Time Series Models.

摘要

The coated abrasive profiles are characterized using the second order continuous autoregressive model. Based on a two sided moving average representation of this model, expressions are derived to calculate the geometry (apex angle, base width and orientation) of an average grain. Experimental results and analysis for six new and one worn coated abrasive are presented; and the capability of the grain geometry parameters to quantize wear is discussed.
