Method of abrading a metal workpiece

A method of abrading a metal workpiece comprising:

• contacting a metal workpiece with an abrasive article, wherein the abrasive article comprises:
• a flexible waterproof backing having a first surface bearing a cured primer coating;
• and
• a plurality of shaped structures, each structure having a distal end spaced from said backing and an attachment end attached to the primer coating on the backing, said shaped structures comprising a mixture of abrasive particles and a cured mixture of thermoplastic and thermoset particulate binder,
• wherein the metal workpiece is contacted with the distal ends of the shaped structures to form an abrading interface;
• moving the abrasive article relative to the metal workpiece while providing sufficient force between the metal workpiece and the distal ends of the shaped structures of the abrasive article to abrade the metal workpiece;
• and
• applying liquid coolant proximate the abrading interface.

A method of abrading a cylindrical metal workpiece comprising:

• contacting a cylindrical workpiece with an abrasive article, wherein the abrasive article comprises:
• a flexible waterproof backing having a first surface bearing a cured primer coating;
• and
• a plurality of shaped structures, each structure having a distal end spaced from said backing and an attachment end attached to the primer coating on the waterproof backing, said shaped structures comprising a mixture of silicon carbide abrasive particles, and a cured thermoset particulate binder,
• wherein the cylindrical workpiece is contacted with the distal ends of the shaped structures to form an abrading interface;
• moving the abrasive article relative to the cylindrical workpiece while providing sufficient force between the cylindrical workpiece and the distal ends of the shaped structures of the abrasive article to abrade the cylindrical workpiece;
• and
• applying liquid coolant proximate the abrading interface.
