  title = {Elastic Deformation and Profile Deviations in Gear Shaping},
  abstract = {<p>In this paper, the effect of elastic tool deflection on profile errors in the gear shaping process is&nbsp;examined. Gear shaping is the primary method of manufacturing internal gears which are a major&nbsp;component in planetary gearboxes. Involute profile errors in the machined part can cause dynamic&nbsp;<br />
issues in the gear’s operation such as vibration, noise, and transmission error. Therefore, the ability&nbsp;to predict profile errors in a virtual environment is crucial for process planners. To predict the&nbsp;elastic deformation of the tool, the cutting forces are first predicted by simulating the gear shaping&nbsp;operation in a multi-dexel based solid modeller. From the solid modeller, the cutter-workpiece&nbsp;engagement is extracted and the cutting force is estimated by determining incremental forces along&nbsp;the cutting edge using the oblique cutting force model. Finally, the tool deflection is then calculated using an estimated static tool stiffness from impact hammer tests. Subsequently, by analyzing cross&nbsp;sections of the virtual gear, profile curve deviations are determined. The simulated deviations show&nbsp;good correlation with experimentally measured profile deviations; however, other sources of error&nbsp;must be researched for improved correlation.&nbsp;</p>
