Simply put, a workpiece is an item that is to be processed or has been processed during the manufacturing process.

[0003] After the workpiece is processed, a radii gauge is needed to measure the curvature of the workpiece surface. When using a traditional radii gauge, first align the center point of the radii gauge with the curvature vertex of the workpiece and align the 0° scale line with the reference edge of the workpiece. Then, observe the intersection of the other side of the workpiece with the radii gauge scale and read the corresponding angle to complete the inspection.

[0004] Although traditional arc gauges can detect the arc of a workpiece, in actual operation, the arc gauge cannot always maintain close contact with the surface of the workpiece, resulting in gaps or slippage during the measurement process, which in turn produces measurement errors and reduces the accuracy of the detection results.
