Total Machining Time for single Facing Operation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Machining Time = (Outside Radius of The Workpiece-Inner Radius of Workpiece)/(Rotational Frequency of Spindle*Feed)
t_m = (r_o-r_i)/(n_s*f)
This formula uses 5 Variables

Variables Used

Machining Time - (Measured in Second) - Machining Time is the time when a machine is actually processing something. generally, machining time is the term used when there is a removal of unwanted material.
Outside Radius of The Workpiece - (Measured in Meter) - Outside Radius of the Workpiece is The radius of the outermost surface of the workpiece, away from the machining tool.
Inner Radius of Workpiece - (Measured in Meter) - The Inner Radius of Workpiece is the radius of the innermost surface of the workpiece.
Rotational Frequency of Spindle - (Measured in Hertz) - Rotational Frequency of Spindle is the number of turns made by the spindle of the machine for cutting in one second.
Feed - (Measured in Meter) - The Feed is the distance the cutting tool advances along the length of the work for every revolution of the spindle.

STEP 1: Convert Input(s) to Base Unit

Outside Radius of The Workpiece: 984 Millimeter --> 0.984 Meter (Check conversion here)
Inner Radius of Workpiece: 579 Millimeter --> 0.579 Meter (Check conversion here)
Rotational Frequency of Spindle: 10 Hertz --> 10 Hertz No Conversion Required
Feed: 0.9 Millimeter --> 0.0009 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_m = (r_o-r_i)/(n_s*f) --> (0.984-0.579)/(10*0.0009)

Evaluating ... ...

t_m = 45

STEP 3: Convert Result to Output's Unit

45 Second -->0.75 Minute (Check conversion here)

FINAL ANSWER

0.75 Minute <-- Machining Time

Time for Facing

Go Process Time = (Outside Radius of The Workpiece-Instantaneous Radius For Cut)/(Rotational Frequency of Spindle*Feed)

Rotational Frequency of Spindle given Machining Time for Facing

Go Rotational Frequency of Spindle = (Outside Radius of The Workpiece-Inner Radius of Workpiece)/(Machining Time*Feed)

Feed of Workpiece given Machining Time for Facing

Go Feed = (Outside Radius of The Workpiece-Inner Radius of Workpiece)/(Rotational Frequency of Spindle*Machining Time)

Total Machining Time for single Facing Operation

Go Machining Time = (Outside Radius of The Workpiece-Inner Radius of Workpiece)/(Rotational Frequency of Spindle*Feed)

Outer Radius of Workpiece given Machining Time for Facing

Go Outside Radius of The Workpiece = Inner Radius of Workpiece+(Rotational Frequency of Spindle*Feed*Machining Time)

Inner Radius of Workpiece given Machining Time for Facing

Go Inner Radius of Workpiece = Outside Radius of The Workpiece-Rotational Frequency of Spindle*Feed*Machining Time

Total Machining Time for single Facing Operation Formula

Machining Time = (Outside Radius of The Workpiece-Inner Radius of Workpiece)/(Rotational Frequency of Spindle*Feed)
t_m = (r_o-r_i)/(n_s*f)

The Facing Operation

Facing on a milling machine is the process of cutting a flat surface perpendicular to the axes of the milling cutter. This process removes the material by rotating the facing tool in the counterclockwise direction as the table feeds the workpiece across the cutter. Face milling can be achieved with an end mill but is often done with a face mill, shell mill, or fly cutter.
