摘要

机械加工是一个不断发展的过程,追求更高的生产率、可靠性和加工材料的质量是该过程不断发展的基础。在机械加工中,刀具刃口的状况对刀具的性能有着重要的影响,刀具刃口经过制造或再刃磨加工后会出现微裂纹、凹凸不平、刃口极其锋利等缺陷。切削刃处理用于消除这些缺陷,这些缺陷源于工具制造和再锐化过程。鉴于上述几点,本工作旨在了解和评估磨料刚毛刷对刃口处理的影响,同时考虑到端铣过程中刃口磨损的演变和刀具寿命。本作品所涉及的研磨刷是3M品牌的技术刷,这些刷子有不同的粒度和两种不同的磨料,碳化硅(SiC)和氧化铝(Al2O3),它们的刷毛由两种不同厚度的尼龙制成。基于文献资料,为了评价这些刷的性能,在这一步中对粗糙度和边缘轮廓等问题进行了分析,结果表明,SiC粒度为1微米的细刚毛刷性能最好,这些刷在工具边缘产生的半径为0.06 mm。抛光工艺处理了两把刀具,这些刀具在AISI P20钢中进行了铣削加工。结果,与未处理的工具相比,处理过的工具具有15.30%的优越性能。除了增加使用寿命外,刃口处理提供了线性侧面磨损,延迟了磨损的存在,如粘连、微裂纹和微芯片。磨料刚毛刷抛光刃口处理是一种有效、可靠的提高刀具加工性能的方法。

INFLUENCE OF EDGE TREATMENT BY POLISHING WITH ABRASIVE BRUSH BRUSHES ON THE LIFE OF THE TOOL FOR THE MILLING PROCESS
Machining is a process in constant evolution, the search for greater productivity, reliability, and quality of machined materials is fundamental for the constant evolution of the process. The condition of the tool edge is of great importance for the tool performance in machining, the edge of a tool after the manufacturing or re-sharpening process has defects such as: microcracks, irregularities, and an extremely sharp edge. The cutting edge treatment is used to remove these defects, which originate from the tool manufacturing and re-sharpening processes. In view of these listed points, this work aims to understand and evaluate the effects of cutting edge treatment by abrasive bristle brushes, taking into account the evolution of wear on the edge and tool life in the end milling process. The abrasive brushes covered in this work are technical brushes from the 3M brand, these brushes have different grain sizes and two different abrasives, silicon carbide (SiC) and aluminum oxide (Al2O3), their bristles are made of nylon of two different thicknesses. Based on the literature and to evaluate the performance of these brushes, points such as roughness and edge contour were addressed in this step, and as a result, the fine bristle brush with a SiC particle size of 1 micron had the best performance, these brushes produced a radius of 0.06 mm on the tool edges. The polishing process treated two tools, these tools went through the milling process in AISI P20 steel. As a result, the treated tools had a superior performance by 15,30% compared to untreated tools. In addition to increasing the useful life, the cutting edge treatment provided linear flank wear, delaying the presence of wear such as adhesion, microcracks, and microchips. The polishing edge treatment with abrasive bristle brushes proves to be an effective and reliable process for improving the performance of machining tools.
