Devices, systems, and methods are provided for controlling a quantity of cutting fluid dispensed for a cutting tool within a CNC or other machining system. The devices, systems, and methods may include controlling multiple fluids such that coolant, lubricant, or other fluids can be delivered at different locations, at different flow rates, have their flow rates changed independently, and/or have their flow rates changed dynamically during a machining operation. In some embodiments, a feedback loop or input may be provided to obtain and/or provide information regarding the machining operationsuch as cutting force, cutting temperature, cutting friction, machining operation, tool in use, work piece geometry, and/or materialand automatically and/or independently modify the fluid flow rates. The fluid may be atomized with air or other gases to minimize the quantities of fluid used. Components in the system may be modular to allow the system to be used with existing and new machining technologies.

A power tool includes a control for the motor of the power tool that senses an operating characteristic of the motor and controls the operation of the power tool based on the sensed characteristic. The sensed characteristic includes variations in reluctance of the motor. A controller may sense changes on load on the motor as a result of interaction between a working element such as a saw blade or drill bit and the work piece. The controlled operation may include variation in speed or torque or both, or may include stopping the motor. Emergency conditions may be sensed by changes in reluctance.

A cutting tool has a cutting bite, a power path, and a housing. The cutting bite includes a cutting edge, a shank that holds the cutting edge, and a sensor attached to the shank. The power path has a first terminal connected to the cutting bite and a second terminal opposite to the first terminal, and supplies power to the sensor. The housing accommodates a battery that stores power to be supplied to the power path, and is connected to the second terminal.

A spindle for a machine tool for machining a metal workpiece, including a motor including a stator and a rotor arranged in a spindle housing, a spindle shaft operationally connected to the motor, a clamping interface for clamping a machining tool, a vibration sensing unit for detecting vibration of the spindle arranged in the spindle housing, and a crash sensing unit configured to detect that a crash event occurred on the spindle. The spindle further includes a tool-position monitoring unit for detecting a position of the clamping interface, a motor temperature sensor arranged closely to the motor on the stator and configured to generate a motor temperature signal, a bearing temperature sensor for measuring a temperature of a bearing arranged on the bearing for supporting the spindle shaft configured to generate a bearing temperature signal, and a spindle diagnosis module arranged in the spindle housing.
