Device and method for integrally machining and measuring optical parts

The invention relates to a device and method for integrally machining and measuring optical parts, belonging to the field of optical part machining. The invention aims at solving the problems that: an off-line measuring manner is mostly adopted in the traditional optical part machining, thus the machining efficiency is low; and the traditional optical part machining equipment cannot satisfy with the requirement of online measuring. According to the invention, a workpiece main shaft, a cutting tool main shaft and a shearing interferometer are mounted on a worktable surface of a machining machine; a workpiece is mounted on the workpiece main shaft; a cutting tool is mounted on the cutting tool main shaft through an oscillating arm and a tool carrier; a numerical control system is used for driving the cutting tool main shaft to rotate and driving the cutting tool to machine the workpiece; the optical axis of a measuring light beam which is emitted by the shearing interferometer and the central line of the workpi
