Diamond tool cutting edge optimization method for edge burr removal

Abstract

A diamond tool edge optimization method for edge burr removal, selects a single crystal diamond tool as the edge material and determines the best crystal plane of the front and rear facets of the tool, establishes a grinding fine burr size prediction model and critical cutting thickness for burr removal Based on the model, the design scheme of the blunt circle radius of the cutting edge based on the accuracy and strength is calculated to realize the optimization of the cutting edge of the diamond tool. The present invention utilizes turning to remove micron-level micron burr cutting edge size optimization design scheme, which significantly improves the stability of single-crystal diamond tool, avoids unfavorable factors such as knife breaking and graphitization, and is suitable for removing micron-level burrs on working edges processing.

Description

technical field [0001] The invention relates to a technology in the field of micromachining of a cutting edge, in particular to a method for realizing optimization of a cutting edge of a diamond cutting edge for edge burr removal. Background technique [0002] In the field of precision machining and micromachining, edge integrity is an important indicator to ensure product quality, and burrs are the most important factor affecting edge integrity. The existence of burrs will have adverse effects on the machining accuracy, assembly accuracy and appearance quality of parts, and the cost of deburring will increase with the complexity and precision of parts. [0003] Based on the fact that the size of the burr is at the micron level, and the range of the defect scale and the functional size are of the same order of magnitude, the amount of burr removal needs to be precisely controlled. If the removal amount is small, the burr cannot be eradicated; if the removal amount is large, ...

Problems solved by technology

The existence of burrs will have a negative impact on the machining accuracy, assembly accuracy and appearance quality of the parts, and the cost of deburring will increase with the complexity and precision of the parts.

[0003] Based on the fact that the size of the burr is at the micron level, and the range of the defect scale and the functional size are of the same order of magnitude, the amount of burr removal needs to be precisely controlled. If the removal amount is small, the burr cannot be eradicated; if the removal amount is large, it will often cause secondary deformation and produce edges Edges are blunt and round, even leading to edge loss and edge collapse, changing the edge geometry and performance, and directly affecting the edge integrity

[0004] The deburring process can be divided into the following four types as a whole: mechanical deburring, thermal deburring, electrical deburring and chemical deburring, but no single deburring method can be achieved. produce any side effects

Moreover, most of the deburring programs and tools are aimed at some specific workpiece geometry, and the flexibility and adaptability of the process are poor.
