Abstract
A fixed abrasive article having a body including abrasive particles contained within a bond material, the abrasive particles including shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, each of the shaped abrasive particles or elongated abrasive particles having a predetermined position or a predetermined three-axis orientation, including a placement angle ranging from +90 degrees to −90 degrees and a rake angle ranging from +90 degrees to −90 degrees.
Claims19
A fixed abrasive article comprising:
- a body having abrasive particles contained within a bond material, the abrasive particles including a plurality of shaped abrasive particles, elongated abrasive particles, or a combination thereof, each of the shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, each of the shaped abrasive particles or elongated abrasive particles having a longitudinal axis defining the longest dimension of a major surface and extending through the midpoint of the body and wherein at least a portion of the shaped abrasive particles or elongated abrasive particles have a predetermined rotational orientation relative to a side surface of the body and the longitudinal axis of the shaped abrasive particles or elongated abrasive particles including a placement angle ranging from +45 degrees to −45 degrees, and wherein the placement angle defines an angle between the longitudinal axis of the shaped abrasive particles or elongated abrasive particles and a radial axis extending through the midpoint of the major surface of the shaped abrasive particles or elongated abrasive particles, wherein the radial axis is perpendicular to a tangent at a side surface of the body and wherein the portion includes at least 50% of the total abrasive particles within the body.
A fixed abrasive article comprising:
- a body having abrasive particles contained within a bond material, the abrasive particles including a plurality of shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, wherein at least a portion of the shaped abrasive particles or elongated abrasive particles have a predetermined rotational orientation relative to a side surface of the body and the longitudinal axis of the shaped abrasive particles or elongated abrasive particles including a rake angle ranging from +45 to −45 degrees, and wherein the rake angle defines an angle between a cutting surface of the shaped abrasive particles or elongated abrasive particles and a line perpendicular to a workpiece surface, wherein the workpiece surface is parallel to the edge of the body and wherein the portion includes at least 50% of the total abrasive particles within the body.
