STEP 0: Pre-Calculation Summary

Formula Used

Material Removal Rate in Drilling = (pi*Machined Surface Diameter^2*Feed Rate in Drilling Operation*Rotational Frequency of Tool)/4
Z_d = (pi*d_m^2*f_d*n_t)/4
This formula uses 1 Constants, 4 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 volume of material removed from workpiece per time unit (usually per minute) while performing drilling operations.
Machined Surface Diameter - (Measured in Meter) - Machined Surface Diameter is the diameter of the inner surface of the cylindrical Job or Workpiece through which drilling operation was done. Which is essentially the diameter of the drilled hole.
Feed Rate in Drilling Operation - (Measured in Meter Per Revolution) - Feed Rate in Drilling Operation refers to the speed at which the cutting tool advances against the workpiece. It essentially controls how much material is removed with each pass of the tool.
Rotational Frequency of Tool - (Measured in Radian per Second) - Rotational Frequency of Tool is defined as the number of rotations per unit time or reciprocal of the time period of one complete rotation of tool.

STEP 1: Convert Input(s) to Base Unit

Machined Surface Diameter: 55 Millimeter --> 0.055 Meter (Check conversion here)
Feed Rate in Drilling Operation: 3.01 Millimeter Per Revolution --> 0.00301 Meter Per Revolution (Check conversion here)
Rotational Frequency of Tool: 793 Revolution per Minute --> 83.0427658056614 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Z_d = (pi*d_m^2*f_d*n_t)/4 --> (pi*0.055^2*0.00301*83.0427658056614)/4

Evaluating ... ...

Z_d = 0.000593859298887292

STEP 3: Convert Result to Output's Unit

0.000593859298887292 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.000593859298887292 ≈ 0.000594 Cubic Meter per Second <-- Material Removal Rate in Drilling

Diameter of Drill Bit given Length of Approach

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

Machining Time for Drilling Operation

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

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 using Feed Formula

Material Removal Rate in Drilling = (pi*Machined Surface Diameter^2*Feed Rate in Drilling Operation*Rotational Frequency of Tool)/4
Z_d = (pi*d_m^2*f_d*n_t)/4

Optimal Material Removal Rate

Usually, in Industries, a higher MRR is preferred as it deduces a faster Machining Operation which can be obtained by increasing the Feed Rate. But a larger feed causes Vibrations and Additional Stresses in the Tool and Workpiece that damage not only the Surface Finish of the Job but also Decreases the Life of the Tool.
