An on-machine measurement device that locates a tip position of a blade of a machining tool provided on a machining device includes: a measurement unit configured to measure, in a workpiece that has been machined by the machining tool, a height of a reference plane not machined by the machining tool and a height of a machined surface machined by the machining tool; and a locating unit configured to locate the tip position of the blade of the machining tool based on information on a machining depth specified at the time of machining of the workpiece, and the height of the reference plane and the height of the machined surface that are measured by the measurement unit.

On-machine measurement device, machine tool, and on-machine measurement method

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.

Estimating device and estimating system

A machine tool for performing a cutting process on a workpiece with a cutting tool, includes: a pre-machining shape acquisition unit configured to acquire the shape of the workpiece before cutting, as a pre-machining shape; a target shape acquisition unit configured to acquire a target shape of the workpiece after cutting; a differential shape acquisition unit configured to acquire a differential shape between the pre-machining shape and the target shape; and a machining path setting unit configured to set machining paths so as to perform the cutting process on the differential shape only.
