Abstract: An indexable plenum and a method of using the plenum to collect dust and/or debris during a cutting or milling process are disclosed. The plenum, when attached to the spindle nose of a conventional machine, enables the conventional machine that does not have a hollow spindle nose to be used with a hollow or conventional solid cutter to remove dust and/or debris generated during the cutting process. The indexable plenum comprises a hollow body and a base plate. Hollow bodies of different shape and size that are able to fit differently shaped and sized cutters are disclosed. The hollow bodies can be designed to releasably engage with the same base plate such that when the base plate is attached to the machine spindle nose, hollow bodies can be exchanged during a milling or cutting process to accommodate correspondingly shaped/sized cutters. In various embodiments, the object that is cut or milled is low density foam.
