Spuds

[rgsparber]

In the context of machining, a “spud” is a pointed metal rod that is used to locate the center of rotation of a mill at a desired point on the XY plane. This point is usually the intersection of two reference surfaces and both the X and Y axes are zeroed. The spud must be mounted in a collet which requires any cutter to be removed. This article presents two tools that avoid disturbing the cutter.
