Provided is a control method for a machining tool that processes a workpiece while causing a tool, which rotates by means of a main shaft motor, and the workpiece, which is secured to a table, to move relative to one another, wherein on the basis of the torque command value, the current command value, or the actual current value of the main shaft motor, calculated is the actual cutting force of the tool that is received from the workpiece at a location which is predetermined during the processing of the workpiece, and the actual cutting force that has been calculated is displayed on a display unit.

A numerical control apparatus has a detector, a condition generator, and a logging processor. The detector detects occurrence of a preset event. The condition generator acquires, as a reference value, first numerical control information at a timing when the occurrence of the event is detected, and performs preset first arithmetic processing by using the reference value to generate a first determination condition. When the first numerical control information satisfies the first determination condition, the logging processor starts a process of logging second numerical control information.

A numerical control system detects a state amount indicating a state of machining operation of a machine tool, creates a characteristic amount that characterizes the state of machining operation from the detected state amount, infers an evaluation value of the state of machining operation from the characteristic amount, and detects an abnormality in the state of machining operation on the basis of the inferred evaluation value. The numerical control system generates and updates a learning model by machine learning that uses the characteristic amount, and stores the learning model in correlation with a combination of conditions of the machining operation of the machine tool.

This control system takes into account the thermomechanical aspects of materials to quickly and easily determine optimal cutting conditions and to automatically control machining to preserve the integrity of the workpiece. This system includes an acquisition module configured to acquire values of a set of input parameters relating to cutting conditions and material properties of the piece, and a microprocessor configured for determining at least one operating cutting parameter representative of a cutting signal from the machining apparatus using a set of output parameters of an integrity model previously constructed during a learning phase. The integrity model connects the set of input parameters to the set of output parameters comprising specific cutting coefficients representative of the material integrity of the piece, and establishes at least one fatigue threshold of the at least one cutting operating parameter. The fatigue threshold allows control of the progress of cutting operations.

An automatic monitoring interval-setting device, a machine tool, and an automatic monitoring interval-setting method by which a monitoring interval monitoring a load applied to a tool is able to be automatically set are provided. An automatic monitoring interval-setting device includes a control device including a memory section which stores a program including G1 to G3 for processing a workpiece by using a tool, and a calculating section which is able to edit the program and executes a monitoring interval setting step of respectively inserting starting monitoring of a load applied to the tool into the front of G1 to G3 and ending the monitoring of the load into the rear of G1 to G3 with respect to the program.

Portable, hand-held, battery operated, hydraulic tools are provided with a tool frame, a force sensor, and a location detector. A piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task, such as to apply a crimp to an electrical connector. The tool determines the maximum force applied to the crimp and records that maximum force along with the geographic location of the tool when the crimp was formed. The maximum force provides an indication of the quality of the crimp and the recorded location allows a potentially defective crimp to be located. Images of crimps can be uploaded to a web service and linked to cycle information for retrieval and review at a later date.

Dynamic service interval scheduling in a machine includes receiving monitoring signals for a plurality of components in the machine each indicative of an operating characteristic upon which a state-of-health (SOH) of one of the plurality of components is dependent. An SOH term is calculated for each one of the components based on the monitoring signals and a stored SOH degradation progression profile. SOH reporting signals are outputted based on a respective one of the SOH terms. The reporting signals may indicate a plurality of different continued service capacities among the components at least some of which are runtime-independent of one or more components in a drive system in the machine. Related apparatus and control logic is also disclosed.
