The main feature of ultraprecision, single point diamond turning (SPDT) is its ability to produce high quality surface finishes on the order of nanometers while meeting tight form tolerances on the order of micrometers. This capability allows for the production of optical devices with minimum ...
Form errorMicro-lens array (MLA) has been widely used for 3D imaging, etc., due to its excellent functional performances. Ultra-precision diamond turning (UPDT) offers a satisfying solution to the high-quality fabrication of MLA with sub-micrometric form accuracy and nanometric surface roughness....
Despite its versatility of fabricating freeform surfaces, the characteristic spiral-shape tool marks due to the diamond turning process can cause scattering as well as surface form error, and therefore degrades the optical performance of the surfaces. As a result, a comprehensive study on the ...

In diamond tool turning process, the actual profile height of point P1(x1,y1) is substituted by the ideal profile height of point P0(x0,y0) because of tool centering error, which results in the form error of machined surface. It is different from the error type of “M-shaped” and “...
