Provided is a machine tool control device with which it is possible to simply set control parameter ranges. This machine tool control device which controls a machine tool comprises: a control parameter-setting unit which sets control parameters; a shaft operation control unit which operates an operation shaft on the basis of the control parameters; and a trigger reception unit which receives a trigger during shaft operation by the shaft operation control unit. The control parameter-setting unit has a specifiable range-setting unit for setting specifiable ranges for the control parameters in response to the trigger reception unit having received the trigger, and sets the control parameters on the basis of the specifiable range.

A machining condition management system includes: a cutting tool that includes a cutting edge and a sensor; a storage that stores a mechanical machining condition and a measurement value; and a processor that performs revision of the mechanical machining condition based on the mechanical machining condition and the measurement value stored in the storage. The processor determines a load on the cutting tool based on the measurement value in a first cutting process under the mechanical machining condition, calculates a revised value for revising the mechanical machining condition for at least one machining interval that has fulfilled a prescribed condition in the determination for the first cutting process, and updates the mechanical machining condition in a second cutting process, based on the calculated revised value, and outputs the mechanical machining condition in the second cutting process.

An apparatus for detecting the status of a tool in a machine tool may include: a sensor unit configured to sense acceleration of a spindle of the machine tool in an x-axis direction and a y-axis direction during processing; and a processing device configured to convert the x-axis signal and the y-axis signal, sensed by the sensor unit, into signals capable of representing a cutting force by processing the x-axis and y-axis signals, detect a resultant force, and plot the detected resultant force on a polar coordinate system.

A method to ascertain a quality of a product formed by a subtractive manufacturing device from a workpiece includes: determining a deflection/test force relation for a deflection of the device; measuring an actually exerted machining force applied by the device to the workpiece; automatically determining a machining force reference for the actually exerted machining force; automatically evaluating whether the actually exerted machining force deviates from the machining force reference. If an actually exerted machining force deviates from the machining force reference, then the method uses the deflection/test force relation to automatically determine for the actually exerted machining force, at least one correction deflection of the device and automatically creating at least one corrected drive control signal to fully or partially reduce the correction deflection.
