STEP 0: Pre-Calculation Summary

Formula Used

Material Removal Rate in Drilling = pi*(Machine Surface Diameter^2)*Feed Speed/4
Z_w-Drilling = pi*(d_m^2)*v_f/4
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Material Removal Rate in Drilling - (Measured in Cubic Meter per Second) - Material removal rate in Drilling (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.
Machine Surface Diameter - (Measured in Meter) - Machine Surface Diameter is the diameter of a cylindrical Job or Workpiece after Machining.
Feed Speed - (Measured in Meter per Second) - Feed Speed is the Feed given against a workpiece per unit time.

STEP 1: Convert Input(s) to Base Unit

Machine Surface Diameter: 55 Millimeter --> 0.055 Meter (Check conversion here)
Feed Speed: 0.25 Meter per Second --> 0.25 Meter per Second No Conversion Required

Material Removal Rate during Drilling Operation using Feed

Go Material Removal Rate in Drilling = pi*(Machine Surface Diameter^2)*Feed Rate in Drilling Operation*Rotational Frequency of Tool/4

Material Removal Rate during Drilling Operation when Enlarging Existing Hole

Go Material Removal Rate = pi*((Machine Surface Diameter^2)-(Work Surface Diameter^2))*Feed Speed/4

Diameter of Drill Bit given Length of Approach

Go Diameter of drill bit = 2*Approach Distance/tan((pi/2)-(Drill Point Angle/2))

Material Removal Rate during Drilling Operation

Go Material Removal Rate in Drilling = pi*(Machine Surface Diameter^2)*Feed Speed/4

Machining Time for Drilling Operation

Go Machining Time = Length of Cut/(Feed Rate*Rotational Frequency of Drill-bit)

Length of Cut using Machining Time

Go Length of Cut = Feed Rate*Machining Time*Rotational Frequency of Workpiece

Drill Point Angle for given Length of Approach

Go Drill Point Angle = 2*atan(0.5*Diameter of drill bit/Approach Distance)

Length of Approach for Drilling Operation

Go Approach Distance = 0.5*Diameter of drill bit*cot(Drill Point Angle/2)

Material Removal Rate during Drilling Operation Formula

Material Removal Rate in Drilling = pi*(Machine Surface Diameter^2)*Feed Speed/4
Z_w-Drilling = pi*(d_m^2)*v_f/4

Why Drill is a Multi-Point Cutting Tool?

If a cutter contains more than one cutting edge that can simultaneously partake in material removal action during machining, then it is called a multipoint cutter. Sometimes drill is classified as a double-point cutting tool because common metal cutting drills contain only two cutting edges; however, drills may contain more than two (3 to 6) cutting edges also (for example, wood cutting twist drills).

How to Calculate Material Removal Rate during Drilling Operation?

Material Removal Rate during Drilling Operation calculator uses Material Removal Rate in Drilling = pi*(Machine Surface Diameter^2)*Feed Speed/4 to calculate the Material Removal Rate in Drilling, The Material Removal Rate during Drilling Operation is equal to the volume of residue formed as a direct result of the removal from the workpiece per unit of time during a Drilling operation. Material Removal Rate in Drilling is denoted by Z_w-Drilling symbol.

How to calculate Material Removal Rate during Drilling Operation using this online calculator? To use this online calculator for Material Removal Rate during Drilling Operation, enter Machine Surface Diameter (d_m) & Feed Speed (v_f) and hit the calculate button. Here is how the Material Removal Rate during Drilling Operation calculation can be explained with given input values -> 0.000594 = pi*(0.055^2)*0.25/4.
