基于二维位移传感器的砂轮表面形貌测量
|
摘要
砂轮表面的三维形貌对保证其磨削质量有重要意义。采用高精度二维位移传感器在线测量砂轮的表面形貌,再通过建立的砂轮三维形貌基准平面和数字滤波方法,用测量数据计算得到砂轮表面的三维形貌评价参数。结果表明:该评价参数与Zeta自动三维测量系统的测量结果基本相同,验证了该评价方法的有效性和实用性,可为砂轮修整及其磨削加工提供参考指标。
The three-dimensional surface morphology of grinding wheel is very important to ensure its grinding quality. A high precision two-dimensional displacement sensor is used to measure the surface topography of grinding wheel on-line, and then the evaluation parameters of the three-dimensional surface topography of grinding wheel are calculated by establishing the reference plane of the three-dimensional topography of grinding wheel and digital filtering method.The results show that the evaluation parameters are basically the same as those measured by Zeta automatic three-dimensional measurement system, which verifies the validity and practicability of the evaluation method, and can provide indexes for grinding wheel dressing and grinding.
