4D-CT imaging of lathe drilling of steel workpieces was demonstrated using synchrotron X-rays at BL05XU of SPring-8. We observed lathe drilling, in which a workpiece is rotated while a drill is kept stationary. Assuming the shape of the workpiece does not change during one rotation, its three-dimensional structure can be reconstructed by CT.
