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.

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.

Systems and methods for improved operation of hand tools are disclosed. Sensors may be configured to monitor one or more operational parameters of a hand tool and collected data may be communicated to the hand tool operator. The data may be compared to predetermined limits for an operational parameter to enable real-time operational diagnostics and quantitative control. Data can be collected across a manufacturing facility and analyzed to help account for variations in technique and skill among operators. An understanding of relationships between monitored operational parameters can lead to improved consistency among finished products and reduction in manufacturing costs. Data may also be stored for future recall and analysis.

A method of changing the crystallographic orientation of a single crystal body is disclosed that includes the steps of characterizing a crystallographic orientation of the single crystal body and calculating a misorientation angle between a select crystallographic direction of the single crystal body and a projection of the crystallographic direction along a plane of a first exterior major surface of the single crystal body. The method further includes removing material from at least a portion of the first exterior major surface to change the misorientation angle.
