Abstract: A method and system for observing and monitoring thermal characteristics of a machining operation, such as a surface finishing operation, performed on a workpiece is disclosed. The surface finishing operation can be performed on the workpiece in order to remove a surface defect, e.g. a parting line, on a surface of the workpiece and/or to provide a mirror-like finish to the workpiece. In one embodiment, an emissive layer is applied to the workpiece to increase a thermal emissivity of the workpiece. In some embodiments, a finishing surface, such as a polishing or buffing wheel, and/or a lubricant used in a finishing operation is monitored. A thermal profile of the surface of the workpiece, finishing surface and/or lubricant can be obtained. The finishing operation can be modified in response to the monitored thermal characteristics to prevent the occurrence of defects and improve the efficacy of the finishing operation.

Abstract translation: 公开了一种用于观察和监测对工件执行的诸如表面精加工操作的加工操作的热特性的方法和系统。 可以在工件上执行表面精加工操作，以便去除表面缺陷，例如， 分切线，在工件的表面上和/或为工件提供镜面状的光洁度。 在一个实施例中，发射层被施加到工件以增加工件的热辐射率。 在一些实施例中，监视在整理操作中使用的精加工表面，例如抛光轮或抛光轮和/或润滑剂。 可以获得工件表面，精加工表面和/或润滑剂的热分布。 可以响应于所监测的热特性来修改整理操作，以防止缺陷的发生并提高整理操作的功效。
