Abstract

The invention discloses a high-precision large-stroke triaxial fast cutter servo device, which belongs to the technical fields of ultra-precision processing, optical component processing and the like, and is suitable for turning and generating a free-form surface diamond with larger non-rotational symmetry. The device is provided with two voice coil motors respectively driving a flexible hinge mechanism so as to make a diamond cutter quickly reciprocate respectively in an X direction and a Z direction, and a fine adjustment mechanism is driven by a piezoelectric stack actuator so as to eliminate additional motion in a Y direction; and two linear gratings are used for respectively detecting the displacements of the diamond cutter in the X direction and the Y direction, and a capacitance sensor is used for detecting the additional displacement in the Y direction. The invention has the advantage of realizing high-precision large-stroke fast reciprocating motion simultaneously in the X direction and the Z direction.

Description

technical field [0001] The invention belongs to the technical field of ultra-precision cutting and optical part cutting, and relates to a tool servo device for free-form diamond turning. Background technique [0002] There can be no geometric constraints between the various value points of the free-form surface, which provides a lot of free design space for optical designers, which means that the optical system based on the free-form surface optical parts can have more excellent optical performance. Such as correcting aberrations, improving image quality, expanding the field of view, increasing the working distance, etc., and one or a few free-form surface optical parts can replace more spherical and aspheric optical parts, thus simplifying the structure of the optical system , lightweight. [0003] Due to the unparalleled performance of free-form optical components, free-form optical components are in increasing demand in many important industrial fields. Diamond turning ...
