Wheel hardness Number given Percentage Volume of Bond material in wheel Solution

STEP 0: Pre-Calculation Summary
Formula Used
Wheel hardness number = (Percentage Volume of Bond Material in Grinding+8-(2.2*Wheel structure number))/1.33
Hn = (Vb+8-(2.2*Sn))/1.33
This formula uses 3 Variables
Variables Used
Wheel hardness number - The wheel hardness number is defined as the constant for every unique material of the wheel.
Percentage Volume of Bond Material in Grinding - The Percentage volume of bond material in grinding is the percentage of the volume of bond material in the grinding wheel.
Wheel structure number - Wheel structure number denotes the spacing of the abrasive grains in the wheel. The lower the structure number, the denser the wheel.
STEP 1: Convert Input(s) to Base Unit
Percentage Volume of Bond Material in Grinding: 16 --> No Conversion Required
Wheel structure number: 2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Hn = (Vb+8-(2.2*Sn))/1.33 --> (16+8-(2.2*2))/1.33
Evaluating ... ...
Hn = 14.7368421052632
STEP 3: Convert Result to Output's Unit
14.7368421052632 --> No Conversion Required
FINAL ANSWER
14.7368421052632 14.73684 <-- Wheel hardness number
(Calculation completed in 00.004 seconds)

Wheel removal parameter from Lindsay's semiempirical analysis
Go Wheel Removal Parameter = (7.93*100000*((Surface Speed of Workpiece/Surface Speed of Wheel)^0.158)*(1+(4*Depth of Dress/(3*Feed)))*Feed^0.58*Surface Speed of Wheel)/(Equivalent Wheel Diameter^0.14*Percentage Volume of Bond Material in Grinding^0.47*Grain diameter of the grinding wheel^0.13*Rockwell Hardness number^1.42)
Wheel surface speed from Lindsay's semiempirical analysis
Go Surface Speed of Wheel = ((Equivalent Wheel Diameter^0.14*Percentage Volume of Bond Material in Grinding^0.47*Grain diameter of the grinding wheel^0.13*Rockwell Hardness number^1.42*Wheel Removal Parameter)/(7.93*100000*((Surface Speed of Workpiece)^0.158)*(1+(4*Depth of Dress/(3*Feed)))*Feed^0.58))^(1/(1-0.158))
Wheel diameter given equivalent wheel diameter
Go Diameter of Grinding Tool Wheel = Equivalent Wheel Diameter*Diameter of Workpiece/(Diameter of Workpiece-Equivalent Wheel Diameter)
Wheel structure Number given Percentage Volume of Bond material in wheel
Go Wheel structure number = (Percentage Volume of Bond Material in Grinding+8-(1.33*Wheel hardness number))/2.2
Wheel hardness Number given Percentage Volume of Bond material in wheel
Go Wheel hardness number = (Percentage Volume of Bond Material in Grinding+8-(2.2*Wheel structure number))/1.33

Wheel hardness Number given Percentage Volume of Bond material in wheel Formula

Wheel hardness number = (Percentage Volume of Bond Material in Grinding+8-(2.2*Wheel structure number))/1.33
Hn = (Vb+8-(2.2*Sn))/1.33

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.
