Device for detecting roundness of arc of tool tip of diamond tool with arc edge

The invention relates to a device for detecting the roundness of an arc of a tool tip of a diamond tool with an arc edge, which belongs to the technical field of the detection of the roundness of thearc of the tool tip of the diamond tool. The device can solve the problem that the existing device for detecting the roundness of the arc of the tool tip of the diamond tool with the arc edge has theshortcomings of low detection precision and inability of meeting the requirement for the high-precision measurement of the roundness of the arc of the tool tip. The device consists of an atomic forcemicroscopy system, a single-chip microcomputer controller, a measurement control computer, a two-dimensional precision displacement workbench and a rotary shaft system, wherein the rotary shaft systemis arranged on the two-dimensional precision displacement workbench, the measurement control computer is used for displaying detection data and outputting a control signal to the single-chip microcomputer controller for controlling the rotation of the rotary shaft system, the relative position of the rotary shaft system and a scanning probe of the atomic force microscopy system is regulated through the two-dimensional precision displacement workbench, and the signal detected by the scanning probe is transferred from the controller in the atomic force microscopy system to the control computerfor monitoring. The device is used for detecting the roundness of the arc of the tool tip of the diamond tool.
