Nowadays, high requirements imposed by mechanical components make it necessary to develop modern production methods. Additive technologies have been dynamically developing in recent years, showing many advantages associated with the fabrication of elements with complex geometries and structures. One of the areas where the potential of additive technologies is exploited is the rapid tooling sector, which is based on the rapid production of tools and components used in various manufacturing methods. Currently, apart from industrial additive fabrication using metal and plastic powders, desktop and low-cost devices for additive manufacturing are gaining more and more importance in the production of functional elements. This paper presents the experimental results obtained from testing the micro-abrasive acrylonitrile-butadiene-styrene ABS tools fabricated by fused filament fabrication (FFF) technology and reinforced with SD 28/20 diamond grains uniformly distributed on the working surface of the tools after they were made. Precision surface grinding operations of 41Cr4 alloy steel were carried out on a portable five-axis CNC milling machine using wheels with continuous and serrated working surfaces. The tool with a serrated working surface enabled a more efficient material removal and produced a better surface finish. In particular, a low wear rate of both FFF-printed tools was confirmed after all experiments. Promising results were obtained, showing the potential for a wider industrial application of the tested tools.
如今，机械部件的高要求使得开发现代生产方法成为必要。近年来，增材技术一直在动态发展，展现出许多与制造具有复杂几何形状和结构的元件相关的优势。利用增材技术潜力的领域之一是快速模具制造领域，该领域基于快速生产用于各种制造方法的工具和部件。目前，除了使用金属和塑料粉末的工业增材制造外，用于增材制造的桌面型和低成本设备在功能元件的生产中越来越重要。本文介绍了对通过熔融长丝制造（FFF）技术制造并在制成后用均匀分布在工具工作表面上的SD 28/20金刚石颗粒增强的微磨料丙烯腈-丁二烯-苯乙烯（ABS）工具进行测试所获得的实验结果。在便携式五轴数控铣床上使用具有连续和锯齿状工作表面的砂轮对41Cr4合金钢进行精密平面磨削操作。具有锯齿状工作表面的工具能够更高效地去除材料，并产生更好的表面光洁度。特别是，在所有实验之后都证实了两种FFF打印工具的低磨损率。获得了有前景的结果，表明所测试工具具有更广泛工业应用的潜力。
