Its compact and dual-mode design makes it ideal for on-machine tool alignment within single-point diamond turning (SPDT) machines, without the need to remove parts. To enhance its OMM capabilities, a defocus-model-based least square (L2) regression fitting algorithm and a convex-hull-based L2 regression are proposed to achieve precise retrieval of deviations in X and Y axes with robustness. Additionally, a high-precision calibration method for testing system misalignment, based on the Zernike high-order approximation model, is applied to relax the OMM system alignment requirements. As a result, rapid tool alignment is achieved without stringent alignment needs. The proposed OMM eliminates the necessity for offline metrology feedback during the tool alignment process and increases process efficiency by at least 50 %.

This paper presents an innovative pneumatic spring stiffness model that incorporates the air-diaphragm coupling effect—a phenomenon in which the air and diaphragm interact synergistically to affect stiffness. The inclusion of this coupling effect alters the effective area and volume of the pneumatic spring, two critical parameters influencing stiffness.
