Precision machining and gauging Diameter-edge visibility

Metal-column edges: trade brightness for a cleaner silhouette boundary

The real side-by-side source image shows a softer boundary under an ordinary backlight and a sharper-looking edge under a collimated panel. The collimated background is dimmer; more brightness is not automatically a better gauging image.

Choose the backlight for edge stability rather than brightness alone.

挑战

A thick round part can collect stray light around its edge. That apparent border can shift the edge selected by a measurement algorithm.

解决方案

The source compares white LS-4FT7070 with white LS-4PFT7070 on a metal-column diameter application. The latter is the proposed light.

The source gives no camera, image scale or measurement method. The camera, macro lens and station below are a new bench proposal, with a local outline region rather than a guaranteed diameter tolerance.

工作原理

  1. 1

    A more directional transmitted field can reduce light wrapping around the boundary of a thick part.

  2. 2

    The source reports less virtual border but supplies no numerical accuracy. A sharper-looking edge must still be calibrated and tested across real height, focus and part variation.

可检测的证据

图像中可见

The collimated-light side shows a more distinct boundary while its background is dimmer.

光源报告

The source describes reduced virtual border in a column-diameter application, without measured uncertainty or a numerical accuracy result.

如何使用此证据

应用实验室照明演示，不是客户部署或合格的生产检验。建议的相机、镜头、夹具和场景间距需要重新测试。源观察结果不建立缺陷尺寸限制、准确性保证或生产误报率。

从图像对比度到生产决策

部件验证项

  1. 01

    Define the physical edge

    Set the diameter datum and edge-fitting rule before comparing apparent borders.

  2. 02

    Calibrate and reload

    Use a reference artefact and repeat loading, focus and allowed height variation.

  3. 03

    Compare usable contrast

    Adjust exposure without saturation and quantify edge stability, not background brightness alone.

Camera and available lens CAD are published models. Light envelopes and the station base/height use printed dimensions. Part shapes, brackets, holders, shielding and spacing are illustrative; they are not reconstructions of a source part or a complete mechanically validated assembly. Light paths explain the proposed arrangement and do not simulate optical performance. The proposed field is derived from the printed camera pixel dimensions and the stated lens magnification/working-distance pair, not measured from the source capture. The camera shows a local silhouette-edge window, not the complete cylinder. The source does not supply the actual part dimensions.
