Provided is a control device for a machine tool that exchanges a tool and machines a work piece on the basis of a machining program, said control device being provided with a machining program analysis unit that analyzes a machining program and extracts, from the machining program, measurement-related information relating to a dimensional measurement of a tool, and with a measurement program generation unit that, on the basis of the measurement-related information and basic tool information input in advance, generates a measurement program for measuring the dimensions of the tool.

This invention provides an information processing apparatus that performs maintenance of a machine tool based on received measurement data. The information processing apparatus includes an acquirer that acquires maintenance information including measurement data by a measuring instrument attached to a machine tool and identification information of the machine tool, a calculator that calculates an operation accuracy of the machine tool using the acquired maintenance information, and a correction information generator that generates correction information of the machine tool based on a calculation result by the calculator.

A method for correcting tool parameters of a machine tool for machining workpieces includes recording measurement values of measured characteristics as actual values of at least one workpiece machined with the machine tool. The measurement values are compared with the default set values of the workpiece. The measurement values of at least two measured characteristics are recorded from at least two parameters of at least one measured characteristic and/or from at least one measured characteristic and from at least one parameter. An average for a tool correction value is calculated from the measurement values and the corresponding set values, with which a correction of the machine tool is performed.

A method for detecting and compensating CNC tools being implemented in an electronic device, receives from a detector first parameters and second parameters in respect of a first tool. Such first parameters include at least one of service life, blade break information, and blade chipping information of the first tool, and such second parameters include at least one of length extension information, length wear information, radial wear information, and blade thickness wear information of the first tool. Based on the first parameters, instructions to process the workpiece are transmitted or not. Upon receiving the second parameters, instructions to adjust operation of the first tool are transmitted, to compensate for deterioration in normal use.

An apparatus for adjusting a knife edge offset in a cutter toolhead having a cutter toolhead frame. The apparatus including a knife moveably coupled to the toolhead, an actuated arm moveably attached to the cutter toolhead frame, a computer controller for controlling the movement of the knife and actuated arm, an abrasive sharpener moveably attached to the actuated arm and adapted to contact the knife, and a sensor adapted to determine a distance between the cutter toolhead frame and the actuated arm. The computer controller of the apparatus is further capable of adjusting the movement of the knife and the actuated arm as a function of the distance determined by the sensor.

A method for processing a workpiece with a tool is provided with holding the workpiece, holding the tool, and moving the held tool relative to the held workpiece in accordance with an NC program including an arithmetic expression to calculate a position of the held tool.

A tool management system includes a CNC for controlling a machine tool and tool management device configured to manage information on a tool. The CNC notifies the tool management device of information on a mounted state of the tool in the machine tool. The tool management device stores tool management data in which tool type data including information common to tool types and tool object data including information on each individual tool are associated with one another. The tool object data includes the information on the mounted state of the tool.
