A method for producing an integrally bladed rotor includes providing imaginary front and rear lattice points on the ridges of the front and rear edges; providing a first imaginary line on positive-pressure and negative-pressure surfaces to connect a first imaginary front lattice point and a first imaginary rear lattice point; providing a second imaginary line on the positive-pressure and negative-pressure surfaces to connect a second imaginary front lattice point next to the first imaginary front lattice point and a second imaginary rear lattice point next to the first imaginary rear lattice point; providing a spiral path on the positive-pressure and negative-pressure surfaces by connecting the first and second imaginary lines with a spiral curve; and cutting the positive-pressure and negative-pressure surfaces by moving a cutting point corresponding to a cutting edge of a turning tool along the spiral path. point around the blade.
A controller includes data collect circuitry configured to collect machining data including a date and a time when at least one machined portion of a workpiece has been machined by a machine tool, temperature circuitry configured to obtain, at predetermined time intervals, temperature data at positions on the machine tool, dimension data input circuitry configured to receive dimension measurement data which includes a dimension of the machined portion after the machined portion has been machined, learning data generate circuitry configured to generate learning data based on the machining data and the dimension measurement data, and machine learning circuitry configured to execute a machine learning based on the temperature data and the learning data to obtain a correction coefficient based on which a displacement caused by a change in a temperature of the machine tool is corrected according to a thermal displacement correction equation.

METHOD FOR PRESSING TAILSTOCK OF MACHINING DEVICE, PRESSING DEVICE, COMPUTER PROGRAM, AND COMPUTER-READABLE STORAGE MEDIUM
This method for pressing a tailstock of a machining device sets a target pressing force for pressing, to a workpiece mounted on a spindle, the tailstock in a first direction along a rotational axis of the spindle. An actuator, which controls moving of the tailstock and the pressing force for pressing the tailstock to the workpiece, is driven so that the tailstock is moved at a first speed in the first direction. When the pressing is detected, the moving of the tailstock is stopped. The tailstock is moved by a first distance in a second direction opposite to the first direction. The tailstock is moved at a second speed slower than the first speed in the first direction. When an input amount to the actuator is a value corresponding to the target pressing force during the tailstock moving at the second speed, the tailstock is stopped.
