Device capable of adjusting rake angle and height of diamond cutter and adjusting method thereof

Abstract

The invention discloses a device capable of adjusting the rake angle and height of a diamond cutter and an adjusting method thereof, and belongs to the technical field of ultra-precision machining. A vertical displacement table is driven by a second stepping motor and arranged on an ultra-precision machine tool, an angle displacement table driven by a first stepping motor is arranged on the vertical displacement table, and a tool installation base is arranged on the angle displacement table. The diamond cutter is placed on the cutter mounting base and is fixed through a cutter fixing block; The first stepping motor and the second stepping motor are controlled by a controller. The angle displacement table is provided with a rotation limiting mechanism. The vertical displacement table, the ultra-precision machine tool and the angle displacement table are assembled. A diamond cutter is mounted on the cutter mounting base and fixed. The circle center position of the angle displacement table is measured. The cutting edge position of the diamond cutter is measured, the distance between the cutting edge of the diamond cutter and the circle center of the angle displacement table is calculated, and the rotating angle and the cutting edge rotating radius of the diamond cutter is input, so that the rake angle of the diamond cutter is rotated to a required angle. According to the invention, the efficiency of the cutting rake angle parameter process test is improved.

Description

technical field [0001] The invention relates to a device capable of adjusting the rake angle and height of a diamond tool and an adjusting method thereof, belonging 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 cuttin...

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
