摘要： The present disclosure relates to abrasive buffing articles (“abrasive buffs”) and methods of making the same. The abrasive buffs include a substrate, such as a fabric, that has been impregnated with an abrasive polymeric composition that includes abrasive particles, such as primary abrasive particles and/or abrasive aggregates, such as spray dried abrasive aggregates. The abrasive buffs are flexible and capable of conforming to and effectively abrading, polishing, and buffing workpieces possessing a complex geometry.

摘要： An abrasive particle can include a coating overlying at least a portion of a core. In an embodiment, the coating can include a first portion overlying at least a portion of the core and a second portion overlying at least a portion of the core, wherein the first portion can include a ceramic material and the second portion can include a silane or a silane reaction product. In a particular embodiment, the first portion can consist essentially of silica. In another particular embodiment, the first portion can include a surface roughness of not greater than 5 nm and a crystalline content of not greater than 60%.

摘要： The present application relates to systems and methods for obtaining real-time abrasion data. An example computer-implemented method could include receiving, at a computing device, sensor data from one or more sensors. The one or more sensors are disposed in proximity to an abrasive product or a workpiece associated with the abrasive product. The one or more sensors are configured to collect abrasion operational data associated with an abrasive operation involving the abrasive product or the workpiece. The computer-implemented method could further include training, based on the sensor data, a machine learning system to determine product specific information of the abrasive product and/or workpiece specific information. The computer-implemented method could also include providing the trained machine learning system using the computing device.

摘要： The present application relates to systems and methods for obtaining real-time abrasion data. An example system includes a remote sensor that is located remotely from a grinding tool and a workpiece. The remote sensor is configured to detect vibration and/or noise associated with a grinding operation involving the grinding tool and the workpiece. The system includes communication interface and a controller configured to carry out operations. The operations include receiving, from the remote sensor, at least one of vibration or noise information associated with the grinding tool and the workpiece. The operations also include determining tool-specific information or workpiece-specific information based on the at least one of the vibration or noise information. The operations yet further include transmitting, via the communication interface, the tool-specific information or workpiece-specific information. The system also includes a remote computing device configured to receive the transmitted tool-specific information or workpiece-specific information.
