Method And Apparatus For Measuring The Straightness Error Of Slender Bodies, With Compensation Of Gravity Deformation

Patent No. EP3701220 (titled "Method And Apparatus For Measuring The Straightness Error Of Slender Bodies, With Compensation Of Gravity Deformation") was filed by Q Tech on Oct 26, 2018. The application was issued on Aug 30, 2023.

Patent Summary

A method and apparatus for measuring straightness errors of elongated-shape elements, such as metal bars, during production. The apparatus uses a static supporting system with multiple bearing elements to maintain the bar in a stable position, while a first detecting system captures the bar's 3D geometry and a second detecting system measures the forces acting on the bar. The apparatus calculates the bar's theoretical shape in the absence of gravitational forces and supporting constraints, and determines the straightness error as a deviation from this theoretical shape.
