Abstract
A particular method includes uniaxially hot pressing a preform that includes abrasive particles in a bonding material to form a bonded abrasive body.
Claims
exact text as granted — not AI-modified1 . A method of forming a bonded abrasive body comprising:
uniaxially hot pressing a preform comprising abrasive particles in a bonding material to form a bonded abrasive body.
2 . The method of claim 1 , wherein during uniaxially hot pressing, the geometry of the preform is substantially altered.
3 . The method of claim 1 , wherein uniaxially hot pressing comprises liquid phase sintering.
4 . (canceled)
5 . (canceled)
6 . The method of claim 1 , further comprising uniaxially hot pressing in one of an oxidizing atmosphere, a reducing atmosphere, or an inert atmosphere.

38 . (canceled)
39 . A method of forming a body comprising:
uniaxially hot pressing a preform comprising abrasive particles to form a body having a relief extending from a plane which extends parallel to an axis of pressing.
40 . The method of claim 39 , further comprising forming the body such that the final shape of the body is asymmetric around the axis of pressing, and wherein the plane defines an exterior surface of the body.
41 . (canceled)
42 . The method of claim 39 , wherein uniaxially hot pressing comprises forming a relief in the body during pressing, wherein the relief extends at an angle to the axis of pressing.
