Formula Used

Proportion of Total Energy Flow = (0.6+0.05*Relative Contact Area of Grain)*100
E = (0.6+0.05*A_g)*100
This formula uses 2 Variables

Variables Used

Proportion of Total Energy Flow - (Measured in Joule) - Proportion of Total Energy Flow is defined as the percentage of total amount of energy transferring into the workpiece.
Relative Contact Area of Grain - (Measured in Square Meter) - Relative Contact Area of Grain is the fraction of the grain's surface area that is in contact with the workpiece during the grinding process.

STEP 1: Convert Input(s) to Base Unit

Relative Contact Area of Grain: 25 Square Centimeter --> 0.0025 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = (0.6+0.05*A_g)*100 --> (0.6+0.05*0.0025)*100

Evaluating ... ...

E = 60.0125

Proportion of Total Energy flowing into workpiece

Go Proportion of Total Energy Flow = (0.6+0.05*Relative Contact Area of Grain)*100

Proportion of Total Energy flowing into workpiece Formula

Proportion of Total Energy Flow = (0.6+0.05*Relative Contact Area of Grain)*100
E = (0.6+0.05*A_g)*100

What do the numbers on a grinding wheel mean?

The type of the wheel is marked as an ISO number and signifies the wheel's shape. For example, ISO Type 52 is a spindle-mounted wheel. The size of the grinding wheel is marked as dimensions in mm. For example, 230 x 3 x 22.2mm. This represents the wheel's diameter x thickness x hole size.
