Description
技术领域Technical Field
本发明涉及切削刀具制备，更具体地说是一种具有阵列微齿结构的球头微铣刀及其制备方法。The invention relates to the preparation of a cutting tool, and more particularly to a ball-end micro-milling cutter with an array micro-tooth structure and a preparation method thereof.
背景技术Background technique
随着微型器件的兴起与发展，微切削技术成为研究热点，然而相比于宏观切削，微铣削加工过程中每齿切削深度与刀具刃口圆弧半径处于同一数量级，因此加工中存在明显的尺寸效应，挤压、犁耕、划擦等作用较为显著，对工件表面完整性造成严重损伤。在实际微铣削加工中，由于工件结构多样、尺寸微小，工件加工表面的形貌难以保证，容易出现毛刺、崩边等严重的加工缺陷。尤其是加工微小腔体结构时，由于排屑空间有限，大量切屑来不及排出，被刀具反复挤压而粘结在微通道内侧，导致腔体壁面形成大量毛刺，严重影响加工表面质量。尤其是球头微铣刀在加工圆形、半圆形等微结构时，受微铣刀刀颈限制，切屑排出更是严重受限，从而导致微结构加工表面质量偏差。此外，目前常见的球头微铣刀多为单刃或双刃结构，加工效率低，刀具磨损快，使用寿命短，较难满足高精度、高效率加工要求。With the rise and development of micro devices, micro-cutting technology has become a research hotspot. However, compared with macro-cutting, the cutting depth of each tooth in micro-milling is at the same order of magnitude as the arc radius of the tool edge. Therefore, there is an obvious size effect in the processing, and the effects of extrusion, plowing, and scratching are more significant, causing serious damage to the surface integrity of the workpiece. In actual micro-milling, due to the diverse structures and small sizes of the workpiece, the morphology of the workpiece surface is difficult to guarantee, and serious processing defects such as burrs and edge collapse are prone to occur. Especially when processing micro-cavity structures, due to the limited chip removal space, a large number of chips cannot be discharged in time, and are repeatedly squeezed by the tool and bonded to the inside of the microchannel, resulting in a large number of burrs on the cavity wall, which seriously affects the quality of the processing surface. In particular, when ball-end micro-milling cutters are used to process circular and semi-circular micro-structures, they are restricted by the micro-milling cutter neck, and chip removal is severely restricted, resulting in deviations in the surface quality of micro-structure processing. In addition, the common ball-end micro-milling cutters are mostly single-edge or double-edge structures, with low processing efficiency, fast tool wear, and short service life, which makes it difficult to meet the requirements of high-precision and high-efficiency processing.
