| 英文摘要 | An ideal pitch button blocking process determines the level of workpiece deformation, especially the high-aspect-ratio optics, during the blocking process and process of polishing later. We have studied the pitch button blocking process by Finite Element Analysis (FEA) according to the thermoelastic equation. Meanwhile, the optimized pitch button blocking has been gotten by FEA which includes the thickness and material of blocking plate, as well as the radius, arrangement, elastic modulus and coefficient of thermal expansion of pitch buttons. The numerical simulation of Nd: glass (empty set100 mmx2 mm thickness) shows that the surface figure change (Delta PV) which is induced by the thermal stress during pitch button blocking process is influenced seriously by the thickness of blocking plate. |
