CALCULATIONS. There are many different types of calculations that can be used to describe specific aspects of the grinding process. However, the most common is related to determining the Grinding Ratio or “G ratio” for short. Simply put, the calculation for the G Ratio is Volume of Work Material Removed divided by the Volume of Wheel Wear. Of course the wheel must be of the type that can

Mill (grinding) Wikipedia
To calculate the needed grinding work against the stone size changing three semiempirical models are used. These can be related to the Hukki relationship between particle size and the energy required to break the particles. In stirred mills, the Hukki relationship does not apply and instead, experimentation has to be performed to determine any relationship. Kick for d > 50 mm

related, and together determine how well a wheel will perform. Damaged wheels or even wheels suspected of being damaged should not be used. Safety steps for proper use of grinding wheels include, but are not limited to: • always having machine guards in place before turning on a grinding wheel • running wheels for at least one minute before actual work begins • always using eye
GRINDING FEEDS AND SPEEDS
Highspeed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels. On the other hand, very low grinding wheel speeds, in the order of 3,000 to 4,000 fpm (about 15 to 20 m/sec) are needed for the surface grinding of various types of

Speeds and feeds Wikipedia
Grinding wheels are designed to be run at a maximum safe speed, the spindle speed of the grinding machine may be variable but this should only be changed with due attention to the safe working speed of the wheel. As a wheel wears it will decrease in diameter, and its effective cutting speed will be reduced. Some grinders have the provision to increase the spindle speed, which corrects for this

CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.
