Time for Facing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Process Time = (Outside Radius of The Workpiece-Instantaneous Radius For Cut)/(Rotational Frequency of Spindle*Feed)
t′ = (r_o-v)/(n_s*f)
This formula uses 5 Variables

Variables Used

Process Time - (Measured in Second) - Process Time is the time for which any process has been carried out irrespective of its completion.
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.
Instantaneous Radius For Cut - (Measured in Meter) - Instantaneous Radius For Cut is the radius of the workpiece surface currently being machined.
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)
Instantaneous Radius For Cut: 120 Millimeter --> 0.12 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′ = (r_o-v)/(n_s*f) --> (0.984-0.12)/(10*0.0009)

Evaluating ... ...

t′ = 96

STEP 3: Convert Result to Output's Unit

96 Second -->1.6 Minute (Check conversion here)

FINAL ANSWER

1.6 Minute <-- Process Time

(Calculation completed in 00.004 seconds)

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.

How to Calculate Time for Facing?

Time for Facing calculator uses Process Time = (Outside Radius of The Workpiece-Instantaneous Radius For Cut)/(Rotational Frequency of Spindle*Feed) to calculate the Process Time, Time for Facing is simply time for which given Facing Process is being done, irrespective of its completion. Process Time is denoted by t′ symbol.

How to calculate Time for Facing using this online calculator? To use this online calculator for Time for Facing, enter Outside Radius of The Workpiece (r_o), Instantaneous Radius For Cut (v), Rotational Frequency of Spindle (n_s) & Feed (f) and hit the calculate button. Here is how the Time for Facing calculation can be explained with given input values -> 0.026667 = (0.984-0.12)/(10*0.0009).

FAQ

What is Time for Facing?

Time for Facing is simply time for which given Facing Process is being done, irrespective of its completion and is represented as t′ = (r_o-v)/(n_s*f) or Process Time = (Outside Radius of The Workpiece-Instantaneous Radius For Cut)/(Rotational Frequency of Spindle*Feed). Outside Radius of the Workpiece is The radius of the outermost surface of the workpiece, away from the machining tool, Instantaneous Radius For Cut is the radius of the workpiece surface currently being machined, Rotational Frequency of Spindle is the number of turns made by the spindle of the machine for cutting in one second & The Feed is the distance the cutting tool advances along the length of the work for every revolution of the spindle.
