1. A method of removing material from one or more workpieces including:
- moving a coated abrasive article comprising a plurality of shaped abrasive particles relative to a surface of the one or more workpieces at a normalized average material removal rate of at least 6 in3/min/in,wherein the one or more workpieces comprise stainless steel,wherein removing material includes a G-ratio variance of not greater than about 28% for at least two different material removal operation at two different normalized average material removal rates within the range of normalized average material removal rates,wherein removing material comprises removing a cumulative amount of material from the one or more workpieces of at least about 7,500 grams/in., andwherein the two different normalized average material removal rates differ by at least about 2 in3/min/in.

18. A method of conducting a high-speed, high-efficiency grinding operation including
removing a cumulative amount of at least about 7,500 grams/in. of material from one or more workpieces comprising stainless steel at a normalized average material removal rate of at least 6 in3/min/in to not greater than 25 in3/min/in by moving a coated abrasive article relative to a surface of the one or more workpieces, wherein the coated abrasive comprises a polymeric binder disposed on a backing material and a plurality of shaped abrasive particles disposed on or in the polymeric binder, wherein the coated abrasive is adapted to have a G-ratio variance of not greater than about 30% for two different material removal operations on stainless steel having normalized average material removal rates that are within the range of at least 6 in3/min/in to not greater than 25 in3/min/in and that differ by at least about 2 in3/min/in.

20. A method of removing material from a workpiece including:
-
abrading a workpiece with a coated abrasive article at a normalized average material removal rate of at least 6 in3/min/in, wherein the coated abrasive article comprising a plurality of shaped abrasive particles, wherein the workpiece comprises stainless steel, wherein the coated abrasive is adapted to achieve a cumulative amount of material removed of at least 10,000 Win while maintaining a normalized specific grinding energy of not greater than 2.5 Hp/(in3/min).
