Abstract: An adaptive bending structure or insert for a lapping device is disclosed. In illustrated embodiments the bending structure provides a wider control width between bending nodes for imparting bending to a workpiece for lapping or longer beam length to increase stroke input at outer ends of the bending structure. In illustrated embodiments, outer bending fingers of the bending structure have a wider width than inner bending fingers to provide the wider control width of the adaptive bending structure. The wider bending fingers of the bending structure connect to actuator fingers of an actuator module to adapt the actuator module to provide an increased control width for controlling bow and curvature of the workpiece during the lapping process.
