Micro-arc edge diamond cutter micro-notch control method based on mechanical grinding method

Abstract

The invention discloses a micro-arc edge diamond cutter micro-notch control method based on a mechanical grinding method. The method sequentially comprises the step 1 of determining the position and size of micro-notches of a cutting edge of a cutter; step 2, grinding the rear cutter face of the cutter, removing micro-gaps on the rear cutter face of the cutter, and meanwhile controlling the arc size of the cutter; step 3, roughly grinding the front cutter face of the cutter, and removing micro-notches near the front cutter face and a cutter tip of the cutter; step 4, finely polishing the frontcutter face of the cutter, removing fine micro-notches and defect areas, and controlling the roughness of the front cutter face and the contour of the cutting edge; and step 5, detecting the qualityof the cutter, determining whether the cutting edge of the cutter is damaged, and if so, returning to the step 2; if the micro-notches of the cutting edge of the cutter are reduced, but the micro-notches still exist, performing the step 4 again until the micro-notches of the cutter disappear and the arc size reaches the required value. The phenomena of cracking, micro-notch recurrence and the likecan be effectively avoided, so that the diamond repair efficiency is improved; and the removal amount is reduced, the repeated utilization frequency of the cutter is increased, and the use cost of the cutter is reduced.

Description

technical field [0001] The invention relates to the technical field of ultra-precision cutting, in particular to a micro-cut control method for a micro-arc edge diamond tool based on a mechanical grinding method. Background technique [0002] With the continuous development of manufacturing technology, microstructured surfaces and microfunctional devices are more and more widely used in the fields of optics, aerospace, mechatronics and biomedicine. These tiny structures generally have highly regular and large The aspect ratio will make the component show some excellent performance when used.

Problems solved by technology

[0011] 3) The micro-arc tool has extremely high requirements on the edge waviness and roughness. After rework, the contour accuracy and surface roughness of the tool tip directly affect the processing quality. The grinding accuracy must be strictly controlled, and it is difficult to achieve precise control.
