摘要： The invention is related to a toolholder (100) for use with a cutting element (200) in a cutting process, wherein the toolholder (100) comprises at least one sensor (114) for detecting an environmental condition; wherein the toolholder (100) comprises a control unit (116) operatively connected to the at least one sensor (114), wherein the control unit (116) comprises a crossbar array (118) of resistive memory devices, and a power source (120) operatively connected to the crossbar array (118), wherein the crossbar array (18) comprises a neural network stored thereon, and wherein the neural network is adapted to determine a condition of the cutting element (200) or of the cutting process based on the environmental condition detected by the at least one sensor (114). The invention also relates to a cutting tool (300) and to a cutting tool assembly (500).

摘要： A processing system includes a cutting tool, a sensor attached to the cutting tool, an analog-to-digital (AD) converter configured to perform sampling on an analog signal output from the sensor to generate a digital signal, and a processing unit. The processing unit is configured to, based on a rotation rate [rpm] of a rotor that rotates about a rotation axis; an upper-limit period that is an upper-limit value of a process period that is a period with which a predetermined process is performed using the digital signal generated by the AD converter; and an upper-limit pitch that is an upper-limit value of an angle pitch [degree] that is a rotation angle between two adjacent sampling time points in a coordinate system representing a phase at a time point of sampling performed by the AD converter in a rotation circle that is a path of a point that rotates about the rotation axis as the rotor rotates, determine the process period and a sampling frequency with which the AD converter performs sampling such that a set value of the angle pitch is equal to the upper-limit pitch or less in a time period taken by the rotor to rotate N times with the process period that is equal to the upper-limit period or shorter, wherein N and (360/ps) are integers of 2 or greater and are relatively prime, where ps denotes the set value.

摘要： A cutting tool includes a shaft extending along a rotation axis and having a first end portion and a second end portion, and a sensor device disposed in such a manner as to surround a portion of the shaft in a longitudinal direction of the shaft. The cutting tool is configured to cut a workpiece by rotating around the rotation axis of the shaft. The sensor device includes a sensor module including a plurality of first sensors configured to detect a first physical quantity of the shaft, a substrate electrically connected to the first sensors, and a wireless communication unit electrically connected to the substrate and configured to transmit a signal including information of the first physical quantity detected by the first sensors to outside and a housing accommodating the sensor module. A region of the shaft surrounded by the sensor device includes a first region having a shape of a 4n-sided polygon when viewed from a direction in which the rotation axis extends. The n is a natural number of two or more. When viewed from the direction in which the rotation axis extends, the plurality of first sensors are arranged on at least two of outer peripheral surfaces of the first region, each of the outer peripheral surfaces of the first region corresponding to one of sides of the 4n-sided polygon, perpendicular lines of the at least two outer peripheral surfaces passing through the rotation axis and intersecting each other at 90 degrees.
