Abstract

Widespread and popular use of ceramic products in various industry sectors necessitates the search for methods of their efficient processing. Lapping technology, which enables obtaining high dimensional and shape accuracy and high surface flatness, is one of the basic methods of finishing hard and brittle technical ceramics with a porous structure. This study analyzed the characteristics and wear value of an SLS-printed abrasive tool intended for single-sided lapping of Al₂O₃ technical ceramics. As earlier research demonstrated, introduction of a 3D printed lapping plate by selective laser sintering (SLS), leads to a significant development in the field of precision machining technology. This method showed not only efficient machining performance on oxide technical materials, but was also characterized by relatively low abrasive wear. Straightness errors were evaluated with the use of a least-squares method (LSQ) and minimum zone method based on control line rotation scheme (CLRS). The proposed model proved the experimental results by identifying a similar location of a higher contact density on the lapping tool, where this location is expected to be the one for bigger wear. Surface topography of the lapping tool depends on the tool wear intensity and as a consequence on its shape error. An SLS-printed lapping plate, by obtaining good technological effects, revealed its potential ability in machining hard and brittle technical ceramics.

三维打印工具在 Al2O3 陶瓷材料平面研磨中的磨损特性研究

陶瓷产品在各行各业的广泛和普遍使用，要求我们必须找到有效的加工方法。研磨技术可以获得较高的尺寸和形状精度以及较高的表面平整度，是加工具有多孔结构的硬脆技术陶瓷的基本方法之一。本研究分析了用于单面研磨 Al2O3 技术陶瓷的 SLS 印刷研磨工具的特性和磨损值。早前的研究表明，通过选择性激光烧结（SLS）技术引入三维打印研磨板，将极大地推动精密加工技术的发展。这种方法不仅对氧化物技术材料具有高效的加工性能，而且磨料磨损相对较低。使用最小二乘法（LSQ）和基于控制线旋转方案（CLRS）的最小区域法对直线度误差进行了评估。通过确定研磨工具上接触密度较高的类似位置，所提出的模型证明了实验结果，预计该位置的磨损较大。研磨工具的表面形貌取决于工具的磨损强度，因此也取决于其形状误差。SLS 印刷研磨板获得了良好的技术效果，显示了其在加工硬脆技术陶瓷方面的潜在能力。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
