A method for a well includes obtaining a dynamic input parameter combination for the well, determining measurements for a rotating control device using a sensor, and predicting a rotating control device wear estimate using rotating control device estimation methods, the measurements, and the dynamic input parameter combination. The method for a well further includes maximizing an instantaneous rate of penetration, while reducing rotating control device failure, to determine an optimized average rate of penetration using the rotating control device wear estimate. Finally, the optimized average rate of penetration is executed for a well.

A method of controlling at least one operation performed on a workpiece is provided. The method includes transmitting, from a first electronic reference device coupled to the workpiece, at least one operating parameter to at least one autonomous device. The method also includes performing, by the at least one autonomous device, the at least one operation on the workpiece in accordance with the received at least one operating parameter.

A method for designing cutting conditions for cutting a workpiece with a cutting tool uses design parameters, including a feed speed, an axial direction cutting amount, a radial direction cutting amount, and a cutting speed of/by the cutting tool. A deflection amount of the cutting tool is calculated from the design parameters. Then a chattering vibration occurs or not in the cutting tool is determined. Depending on the determination result, a maximum cutting thickness of the workpiece is calculated. Then a cutting temperature of the cutting tool is calculated. Then whether a tool life of the cutting tool is satisfied or not is determined. Depending on the determination result, a cutting efficiency of the cutting tool is calculated and compared with data of a cutting efficiency stored in advance. When the calculated cutting efficiency is a maximum value among the data, the design parameters are used as the cutting conditions.

A system and method for a self-contained self-calibrating modular manufacturing device having modular tools and parts configured to collectively accomplish a specific task or function. The modular device includes a housing that has a mount configured to engage a robotic arm or other form of maneuvering actuator (such a crane or gantry). The housing provides a base by which additional modules are mounted and coupled. The modular device also includes an interface configured to communicate with a remote control system capable of controlling the robotic arm. Such modules work in conjunction with each other to accomplish tasks and functions. In a self-contained self-calibrating modular manufacturing device, a processor disposed in the housing is configured to control the functional tools (e.g., each end-effector) independent of the overall manufacturing control system as well as use local sensors to determine aspects of an underlying manufactured items for calibration purposes.

A numerical controller of a machine tool changes a feed speed of a feed shaft and a spindle rotation speed, in accordance with a current position of a rotary tool in a specified arbitrary area above and below a position where a workpiece and the rotary tool come in contact with each other.

A numerical value controller for a machine tool includes a storage unit storing a machining program for drilling a hole in a workpiece in accordance with relative movement between a tool and workpiece in a depth direction, and a control unit controlling the relative movement between the tool and workpiece based on the machining program and that moves the tool relative to the workpiece in the depth direction from a return point to a hole bottom point. The return point is a position retracted in the depth direction from a workpiece surface where the tool starts to perform drilling. The machining program includes a command for a workpiece height point as a position of the workpiece surface. The control unit moves the tool relative to the workpiece in the depth direction at a relative rate higher than a cutting feed rate from the return point to the height point.

A method for operating a power tool, wherein the power tool is initially operated with a first combination of operating parameters such that a first working progress is obtained. During operation of the power tool with the first combination of operating parameters, the first working progress can be determined and compared with a second working progress that is obtained when the power tool is operated with a second combination of operating parameters. Depending on the result of the comparison, the power tool can continue to be operated with the second combination of operating parameters or the power tool can return to operation with the first combination of operating parameters. This comparison of the working progresses can be repeated until a maximum, i.e. optimal working progress is reached or found. A power tool, wherein the power tool is preferably in the form of a drill, preferably a core drill.
