High-efficiency and high-precision detection device for circular arc roundness of cutter point of diamond cutter

Abstract

The invention provides a high-efficiency and high-precision detection device for circular arc roundness of a cutter point of a diamond cutter and belongs to the technical field of cutter detection devices. A precision air flotation shafting is vertically arranged at the center of a vibration isolation platform; a fine-aligning device is fixedly arranged at the upper end part of the precision air flotation shafting; a cutter fixture is fixedly arranged at the upper part of the fine-aligning device; a stereoscopic microscope system is arranged above the cutter fixture; and an atomic force microscope (AFM) system is arranged above one side of the cutter fixture. According to the high-efficiency and high-precision detection device disclosed by the invention, the stereoscopic microscope system assists the fine-aligning device in aligning, so that the aligning precision is increased, the defect that the measurement range of the AFM is narrow is overcome, and three-dimensional measurement with high measurement precision is realized; the problem of precision measurement of the circular arc roundness of the cutter point of the diamond cutter with a circular arc edge can be solved; and measurement data of the circular arc roundness can be used for reflecting dynamic characteristic of a cutter grinding machine, evaluating the cutter grinding quality of the cutter and providing data support for cutter compensation in the numeric control single-point diamond turning.

Description

technical field [0001] The invention relates to a high-efficiency and high-precision detection device for the circular arc roundness of a diamond tool tip, and belongs to the technical field of tool detection devices. Background technique [0002] Ultra-precision machining technology has become a key technology for success in international competition. The development of cutting-edge technology, the development of national defense industry, and the development of microelectronics industry all require instruments and equipment manufactured by ultra-precision processing. Now ultra-precision cutting is the use of precision single crystal natural diamond tools to process non-ferrous metals and non-metals, which can directly cut out ultra-smooth processing surfaces. Ultra-precision machining technology occupies a very important position in the manufacture of cutting-edge products and modern weapons. [0003] The high precision of ultra-precision machining is not only reflected ...

Problems solved by technology

However, due to the small scanning range of the AFM itself, it is impossible to directly measure the overall profile of the flank surface of the tool, so it is impossible to directly obtain the roundness of the tool nose arc
