ProblemDie casting often leaves witness lines on components as a necessary side effect of mould design. As moulds wear, the position and extent of flashing and parting lines change. Conventional automation does not adapt to these changes, causing inconsistencies between early and late production and sometimes resulting in non-conforming parts. Unexpected material can also cause excessive tool wear, further adding to the costs of rigid automation methods
SolutionRivelin's metalworking tools are used to blend parting lines while adapting to the variable geometry and the presence of flashing using a 3D vision system and dynamic planning capability. Our grinding-specific force control system reacts to non-linear machining forces ensuring tool longevity and surface finish consistency. A high-speed version of our robot controller achieves the demanding takt times required by volume production.
