Metal removal rate given workpiece removal parameter Solution

STEP 0: Pre-Calculation Summary
Formula Used
Metal removal rate = (Thrust Force-Threshold Thrust Force)*Workpiece removal parameter
Zw = (Ft-Ft0)*ΛW
This formula uses 4 Variables
Variables Used
Metal removal rate - (Measured in Cubic Meter per Second) - Metal removal rate (MRR) is the amount of material removed per time unit (usually per minute) when performing machining operations such as using a lathe or milling machine.
Thrust Force - (Measured in Newton) - Thrust Force acting perpendicular to the job piece.
Threshold Thrust Force - (Measured in Newton) - Threshold thrust force is defined as the initial thrust force of the given system.
Workpiece removal parameter - Workpiece removal parameter is the ratio of the volume of workpiece removed per unit time per unit thrust force.
STEP 1: Convert Input(s) to Base Unit
Thrust Force: 311.6 Newton --> 311.6 Newton No Conversion Required
Threshold Thrust Force: 12 Newton --> 12 Newton No Conversion Required
Workpiece removal parameter: 10 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Zw = (Ft-Ft0)*ΛW --> (311.6-12)*10
Evaluating ... ...
Zw = 2996
STEP 3: Convert Result to Output's Unit
2996 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
2996 Cubic Meter per Second <-- Metal removal rate
(Calculation completed in 00.004 seconds)

Machine infeed speed given workpiece and wheel removal parameter
Go Machine Infeed speed = Feed Speed*(1+(Wheel Removal Parameter*Diameter of Workpiece/(Workpiece removal parameter*Diameter of Grinding Tool Wheel)))
Feed speed given workpiece and wheel removal parameter
Go Feed Speed = Machine Infeed speed/(1+(Wheel Removal Parameter*Diameter of Workpiece/(Workpiece removal parameter*Diameter of Grinding Tool Wheel)))
Diameter of wheel given feed and machine infeed speed
Go Diameter of Grinding Tool Wheel = Wheel Removal Parameter*Diameter of Workpiece/(((Machine Infeed speed/Feed Speed)-1)*Workpiece removal parameter)
Diameter of workpiece given feed and machine infeed speed
Go Diameter of Workpiece = Workpiece removal parameter*Diameter of Grinding Tool Wheel*((Machine Infeed speed/Feed Speed)-1)/Wheel Removal Parameter
Diameter of workpiece given Metal removal rate
Go Diameter of Workpiece = Metal removal rate/(Feed Speed*pi*Width of Grinding Path)
Width of cut given Metal removal rate
Go Width of Grinding Path = Metal removal rate/(Feed Speed*pi*Diameter of Workpiece)
Feed speed given Metal removal rate
Go Feed Speed = Metal removal rate/(pi*Diameter of Workpiece*Width of Grinding Path)
Metal removal rate given Diameter of workpiece
Go Metal removal rate = pi*Diameter of Workpiece*Width of Grinding Path*Feed Speed
Metal removal rate given workpiece removal parameter
Go Metal removal rate = (Thrust Force-Threshold Thrust Force)*Workpiece removal parameter
Wheel removal rate given Wheel removal parameter
Go Wheel Removal Rate = Wheel Removal Parameter*(Thrust Force-Threshold Thrust Force)
Machine infeed speed given Feed speed in Grinding
Go Machine Infeed speed = Feed Speed+(Diameter of Grinding Tool Wheel/2)
Diameter of wheel given Feed speed in Grinding
Go Diameter of Grinding Tool Wheel = 2*(Machine Infeed speed-Feed Speed)
Feed speed in Grinding
Go Feed Speed = Machine Infeed speed-(Diameter of Grinding Tool Wheel/2)
Grinding ratio
Go Grinding Ratio = Workpiece removal parameter/Wheel Removal Parameter
