A Hough Transform Based Approach for Accurate Evaluation of Geometric Tolerances

9523120制造零件的质量和可靠性的持续改进需要明确的方法和指南，以便准确、快速和一致地检验零件并解释检验数据。本研究旨在开发一种基于霍夫变换法的计算尺寸公差和平直度最小区域的方法。与目前使用的方法不同，这种用于评估制造零件的几何公差的技术是精确的，因此更适合于精密应用。数据将从来自三个不同制造商的实际工业部件中收集，他们将合作将新技术与他们目前使用的尺寸、平面度、直线度和方向公差方法进行比较。目前，大多数制造商使用近似方法来验证形位公差。这可能会导致降低产品质量的错误，特别是对于精密加工。这项研究的结果可以导致更准确和高效的形位公差检测。由于该方法是精确的，而不是近似的，因此它对精密制造特别有用。如果成功，建议的方法将适用于广泛的制造业。

9523120 Anand Continuous improvement of the quality and reliability of manufactured parts requires clear methods and guidelines for accurate, fast and consistent inspection of parts and interpretation of inspection data. This research aims to develop a technique for calculating size tolerances and the minimum zones for flatness and straightness based on the Hough Transform method. This technique for evaluating geometric tolerances of manufactured parts, unlike the methods currently used, is exact and is thus more appropriate for precision applications. Data will be collected from actual industrial parts from three different manufacturers who will collaborate to compare the new technique with the methods they currently use for size, flatness, straightness, and orientation tolerances. Most manufacturers currently us approximate methods to verify geometric tolerances. This can result in errors that degrade product quality, especially for precision machining. The results of this research could result in more accurate and efficient inspection of geometric tolerances. Since the method is exact rather than approximate, it should be particularly useful for precision manufacturing. The proposed method has application to a broad range of manufacturing industries, if successful.
