In high-speed machining it is of key importance to avoid any collision between the machine tool and the machining setup. If the machining setup has not been assembled correctly by the operator and does not conform to the 3D CAD model sent to the machining unit, such collisions may occur. This paper presents a new chain-processing-based computer vision system to automatically avoid collision between tool and machining setup components by checking that the actual machining setup is in conformity with the desired 3D CAD model used to generate the tool trajectory. This computer vision system utilizes a single camera to automatically check conformity before the start of the machining operation. The proposed solution was tested in different kinds of machining setups , and each step of the proposed chain was evaluated. The results show the robustness of the solution for different kinds of machining setups .
