Abstract

A tool for machining a workpiece may comprise multiple parts that have different temperatures when the tool is being operated. To reduce or, in some cases, eliminate thermal radiation between the multiple parts, the tool may incorporate one or more devices that manipulate the thermal radiation. Such devices may be disposed along one or more of the multiple parts and, in some examples, between two or more parts of the tool. These devices may also help reduce and, at times, eliminate thermal radiation between the tool parts and the surrounding environment.
