Abstract
An apparatus, system and method for grinding or polishing an optic is provided. The apparatus includes a shell adapted to a bending profile, torque actuators attached at an outer edge of the shell and coupled to each other, a tensioning system attached at the outer edge of the shell, and a control system for computing the bending profile and controlling the torque actuators and tensioning system. The torque actuators and tensioning system apply bending moments to the edge of the shell to adapt the shell according to the bending profile provided by the control system. A calibration system further corrects errors in a measured bending profile.
