The manufacturing process Single-Pass-Honing is mostly used when, among other things very high demands are placed on the holes to be processed in terms of form and dimensional accuracy. Process features that contribute to these improvements in comparison to other manufacturing processes are on the one hand very high tool rigidity, and secondly, that the tool is filling the whole bore hole. Unlike conventional honing tools that require the presence of a honing machine or special plug-ins to expand the honing stones by an integrated mechanism the tools of Single-Pass-Honing can be used in commercially available machine tools, because the honing stones are fixed to the diameter to be manufactured before machining.During Single-Pass-Honing almost the entire workpiece material is cut during the first plunge of the tool into the cylinder, the so-called Intensivzerspanung. This process results in significant disadvantages in comparison to the long-stroke-honing, like very high machining forces and torques, lower axial velocities and in particular the addition of the chip space of honing stones. Significant disadvantages that results in comparison to the long-stroke-honing, are very high machining forces and torques, lower axial velocities, the loading of the chip space of honing stones with loose workpiece material and a flattening of the abrasive grains caused by the uniaxial load. Within the described research project it is planned to overcome these disadvantages by adequate methods.At previous investigations it was found that a significant reduction in machining forces and torques could be generated by a temporarily reversal movement of the honing tool. It can be assumed that the chip space of the honing stones was released by this reversal movement. Within the proposed research project it should be determined whether the systematic influencing of the tool movement has an effect to improve the process of Single-Pass-Honing during the Intensivzerspanung. By overlaying the axial and tangential velocities with particular oscillating components the loading direction can be influenced at the individual abrasive grains similar to the preliminary investigations. The main objective of the proposed research project is therefore to identify the effect of overlaying dynamic velocities on process parameters and work results in Single-Pass-Honing.

当制造过程单通式培训大多是在以形式和尺寸准确性来处理的孔上非常高的需求时使用的。与其他制造过程相比，有助于这些改进的过程功能一方面是非常高的工具刚度，其次，该工具填充了整个孔洞。 Unlike conventional honing tools that require the presence of a honing machine or special plug-ins to expand the honing stones by an integrated mechanism the tools of Single-Pass-Honing can be used in commercially available machine tools, because the honing stones are fixed to the diameter to be manufactured before machining.During Single-Pass-Honing almost the entire workpiece material is cut during the first plunge of the tool into the cylinder, the so-called Intensivzerspanung。与长冲程的造型相比，此过程导致了明显的缺点，例如非常高的加工力和扭矩，较低的轴向速度，尤其是增加了磨练石头的芯片空间。与长冲程园艺相比，导致的重要缺点是非常高的加工力和扭矩，较低的轴向速度，用宽松的工件材料磨练石头的芯片空间的负载以及由单轴负载引起的磨碎的磨料。在所描述的研究项目中，计划通过足够的方法克服这些缺点。在先前的研究中，发现磨练工具的暂时逆转运动可以大大减少加工力和扭矩。可以假设，磨练石的芯片空间是由这种逆转运动释放的。在拟议的研究项目中，应确定工具运动的系统影响是否有效改善在Intensivzerspanung期间的单次训练过程。通过覆盖具有特定振荡成分的轴向和切向速度，可以在类似于初步研究的单个磨料晶粒上影响载荷方向。因此，提出的研究项目的主要目的是确定叠加动态速度对过程参数和工作的影响，从而导致单次训练。
