摘要
Abstract
To address the challenges of insufficient cutting accuracy and low production efficiency caused by clamping er-rors,machining inaccuracies,and inconsistent installation angles of shearer drum end discs during flame cutting,an auto-mated cutting workstation based on 3D visual dynamic compensation was developed.This workstation integrates a robot,po-sitioner,dedicated fixture,and 3D camera,utilizing offline programming to generate ideal cutting trajectories embedded with dynamic compensation commands.During operation,the system employs a 3D camera to capture images of the work-piece's positioning blind holes and determines the workpiece's center and rotational center using the three-point circle deter-mination method.Based on the positioner's rotation angle,the system calculates the workpiece's center displacement dur-ing rotation and determines the necessary translational and rotational compensation values.Field trials demonstrated that the system achieves an average radial error consistently below 1 mm in flame cutting while reducing the cutting cycle time by 20%-30%.This significantly enhances cutting accuracy and production efficiency while minimizing manual operational risks.The study confirms that this automated workstation,integrating offline programming,3D vision,and dynamic compen-sation,effectively corrects cutting errors in shearer drum end discs.It offers high engineering applicability and strong poten-tial for widespread adoption,providing a reliable technical solution for precision machining of large rotating workpieces.关键词
