The multi-axis dynamometer provides detailed information regarding the forces developed between the machine tool or bit and the workpiece during machining operations. Force sensing is provided along three mutually orthogonal axes, sensing being provided in opposite directions along two of the axes. A housing is split along its diagonal to form two portions that connect together at one corner, a clamp bolt adjustably securing the two opposite corners together. A workpiece holder receptacle is provided between the two portions, and a workpiece fits closely within the receptacle. Four sensors are installed on the four walls of the receptacle, and a fifth sensor is installed on the floor of the receptacle. Preload is applied to the sensors by adjusting the clamping force of the clamp bolt. Motion of the workpiece during machining operations produces forces upon the sensors, the sensor output being received by a microcontroller and transmitted for further use. |
