Abstract
A system and method for vibratory cutting, including in the manufacture of ceramic honeycomb bodies. The apparatus includes a transducer configured to generate vibrations with respect to an axial direction. A cutting element is configured to receive and oscillate axially in response to the vibrations. The cutting element has a blade having a width, an axial length, and a thickness. A cutting plane of the blade is defined with respect to the width and the axial length. The blade has opposing side surfaces that extend parallel to the cutting plane. The thickness extends perpendicular to the cutting plane between the opposing side surfaces. A set of fluid bearings are configured to exert fluid pressure on each of the opposing side surfaces to constrain vibrations of the blade oriented in directions transverse to the cutting plane.
