A Method for Adjusting Rake Angle and Height of Diamond Tool

Abstract

The invention discloses a method capable of adjusting the rake angle and height of a diamond tool, which belongs to the technical field of ultra-precision machining. The vertical displacement stage is driven by the second stepping motor and set on the ultra-precision machine tool, and there is an angle displacement stage driven by the first stepping motor on it, and there is a tool mounting base on the angular displacement table; the diamond tool is placed on the tool mounting base and passed The tool fixing block is fixed; the stepper motor 1 and stepper motor 2 are controlled by the controller; the angle displacement table has a rotation limit mechanism. Assemble the vertical translation stage with the ultra-precision machine tool and the angular translation stage; install the diamond tool on the tool mounting base and fix it; measure the center position of the angular translation platform; measure the position of the diamond tool edge, and calculate the relative angular displacement platform center of the diamond tool edge Input the turning angle of the diamond tool and the turning radius of the cutting edge; make the rake angle of the diamond tool turn to the required angle. The invention improves the efficiency of the cutting rake angle parameter process test.

Description

technical field [0001] The invention relates to a method for adjusting the rake angle and height of a diamond tool, which belongs to the technical field of ultra-precision machining. Background technique [0002] With the development of technology, the demand for ultra-precision machining is becoming more and more extensive. [0003] At present, ultra-precision components manufactured using ultra-precision machining technology have been widely used in the fields of national defense modernization, computers, electronics, and modern biomedicine. [0004] In ultra-precision cutting, cutting process parameters such as cutting rake angle, feed per revolution, depth of cut, spindle speed, type of cutting fluid, etc. have an extremely important impact on the final cutting quality, and different materials often correspond to different cutting results. Optimum cutting process parameters. In ultra-precision cutting, in order to seek the best cutting rake angle parameters for differe...

Problems solved by technology

[0005] In the traditional cutting rake angle parameter process test, the cutting rake angles of different angles are obtained by padding wedge blocks with different angles under the diamond tool handle, or manually adjusting the tool holder, but after each adjustment of the diamond tool rake angle, The position of the cutting point will change, so it is necessary to adjust the height and position of the tool. This process often takes hours or days to obtain a set of process parameter data, which consumes a lot of precious time for front-line scientific research staff. time; and the accuracy of manual adjustment is poor
