Technical difficulties in Micro-Nano machining of free surface
The Micro-Nano machining technology of free-form surface integrates the latest achievements of various contemporary disciplines to meet the needs of high precision and high reliability of surface of vehicle systems and core optical components. At the same time, the constraints in the processing process are more stringent, the processing technology is more difficult, and the processing process is more complex.
Stress and deformation, tooling design, tool wear and machining environment may affect the image quality of the optical surface during Micro-Nano machining of free-form surface. Especially in the processing of large parts, the workpiece will produce large stress because of a large number of cutting materials, which has a great impact on the accuracy of the workpiece, and the control of stress and deformation is particularly critical.
