摘要：

针对成形磨砂轮精密磨削加工中准确高效地检测砂轮形状精度的需求，提出砂轮廓形参数在位检测新方法。首先采用线状激光位移传感器采集砂轮表面微观形貌数据，构建测量矩阵模型，再通过滤波去噪、宏观轮廓线提取、非线性曲线拟合等算法分析处理出砂轮廓形曲率半径和圆度误差检测指标。通过磨削验证试验分析和检测不确定度评定，证明该方法稳定可靠，检测结果可以准确反映工件加工精度，满足复杂圆弧廓形砂轮检测需求，具有较好的工程应用价值。

Abstract: Aiming at the requirement for accurate and efficient detection of grinding wheel profile parameters in forming precision grinding processing, an in-situ measuring method for wheel profile parameters was proposed without precedent. Firstly, the grinding wheel global surface micro-topography data was measured through a linear laser displacement sensor, which constructed the measurement matrix model. Secondly, the matrix model was analyzed and processed through the algorithms of filtering, contour line extracting, non-linear curve-fitting, etc. Finally, the curvature radius and roundness error of wheel profile was calculated. The detection results of grinding verification experiment and uncertainty evaluation show that the new method is stable, reliable and can predict grinding accuracy, which can satisfy the detection requirement for wheel circular-arc profile. It is of great significance for the engineering application.
