Abstract
Single pass honing is a process that consists of removing material in only one complete stroke (down and up movement) of the tool. In this process, the tool diameter is preset. The objective of this study was to verify the influence of axial speed and tangential speed of the tool on the cutting force and the moment generated during the single pass honing on sliding bearings. A complete 3² factorial design was carried out, with nine conditions evaluated resulting in 27 tests, considering one test and two replicas. The varied input parameters were: axial speed at 3.3; 3.9 and 4.5m/min and tangential velocity at 16; 21 and 26m/min. An expanded tool was used to remove 15µm of material in a 195mm stroke. It was found that the axial and tangential velocities have a significant influence on the generated forces. It was noted that the cutting force can be reduced by up to 50% and the moment by up to 30% depending on the tangential speed adopted (16 to 26 m/min). However, there is an increase in cutting force by up to 50% and the moment by up to 20% with an increase in axial speed. It was also verified that, due to the elastic return of the material, there are machining forces during the return stroke of the tool to its initial position.
