ABSTRACT:
An apparatus for directing chips emanating from a workpiece being machined by a tool toward an outlet spaced from the workpiece. The apparatus comprises an enclosure surrounding the workpiece and tool for confining chips emanating from the workpiece to the enclosure for removal via an outlet. The enclosure includes spaced-apart first and second wall portions, a top portion, a bottom portion, a first end portion comprising separate tool and workpiece openings, a second end portion and the outlet located proximate the intersection of the bottom portion and the second end portion whereby a majority of chips emanating from the workpiece are projected toward and collide with the second end portion after which the majority of chips fall to the bottom portion and/or the outlet. Alternatively and preferably, the enclosure comprises a curved inner surface and the chips are directed toward and then travel along the inner surface into an outlet. The enclosure preferably further comprises means to project a gaseous stream along at least a portion of the inner surface for urging chips toward and/or into the outlet. The enclosure may also include means to enhance airflow from the outlet.
