Abstract
An estimating device estimating a rotary axis position of a workpiece includes first and second position acquisition units acquiring tool positions in first and second directions, a load acquisition unit acquiring first and second directional loads of the tool in the first and second directions, a determination unit determining whether or not the first and second directional loads each are a threshold or less, a turning control unit performing a lathe turning on the workpiece until the first directional load becomes the threshold or less and thereafter performing a lathe turning thereon until the second directional load becomes the threshold or less, and an estimating unit estimating the rotary axis position based on a first directional position of the tool when the first directional load has become the threshold or less, and a second directional position thereof when the second directional load has become the threshold or less.
