摘要:

针对ELID磨削砂轮表面氧化膜的厚度测量及生长特性,采用激光和涡流传感器进行氧化膜的厚度模拟测试,以验证测量系统的准确性,并在预修锐阶段对氧化膜的生长特性进行观察。研究结果表明:在前期,氧化膜沿砂轮半径向内生长的速度大于向外生长的速度,且基本呈线性生长,氧化膜生长速度最快;在后期,向内生长速度减缓,向外生长速度稍快,但氧化膜总体生长速度变慢。

Abstract:

In order to measure thickness and study on growth behaviors of oxide layers on grinding wheel surface in ELID, the measurement system accuracy was verificated with laser and eddy current sensor for simulation measurement of oxide layers, Growth behaviour of oxide layers were measured in pre-dressing process, and 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. 

Key words: electrolytic in-process dressing(ELID), oxide layer, measurement, growth behavior, sensor
