If the rounded corners also have high-precision technical requirements, it will have a great impact on the subsequent processing quality of the workpiece. As shown in Figure 1, the existing detection scheme generally uses 3 points to determine a section of arc, and the size of the rounded corner is determined based on the size of the arc. Due to the different points selected each time, the measurement error is relatively large, especially when the rounding is irregular.

The radius of the largest circle drawn is larger than R, and the area of the smallest circle drawn is smaller than R. When the four values of X, Y, R are small, and R is large Within the round tolerance is acceptable.

本发明利用类似于形状公差(线轮廓度)的概念,将倒圆角只是3点确定一段圆弧的尺寸,拆分成4个相关数据,并以此4个数据结果来判定倒圆角。4个测量数据均在倒圆角公差内即为合格,同时X与Y数据差值越小越好,R小与R大数据差值越小越好。 The present invention utilizes a concept similar to shape tolerance (line profile degree) to determine the size of a section of circular arc at only 3 points for rounding, split it into 4 related data, and judge the rounding based on the 4 data results. The 4 measurement data are all within the rounding tolerance, which is qualified, and the smaller the difference between X and Y data, the better, and the smaller the difference between R small and R large data, the better.

本发明具有以下优点: The present invention has the following advantages:

1、可提供更详细的测量数据,为工件修正或设备调试提供可靠信息; 1. It can provide more detailed measurement data and provide reliable information for workpiece correction or equipment debugging;

2、检测准确,有效地保护了后续加工使用的工装夹具。 2. The detection is accurate and effectively protects the tooling and fixtures used in subsequent processing.
