Machining Time for Turning Operation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Machining Time = Length of Cut/(Feed Rate*Angular Velocity of Job or Workpiece)
t_m = L_cut/(f*N_v)
This formula uses 4 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.
Length of Cut - (Measured in Meter) - Length of cut (LOC) is a measurement of the functional cutting depth in the axial direction for a machining process.
Feed Rate - (Measured in Meter Per Revolution) - Feed Rate is defined as the tool's distance travelled during one spindle revolution.
Angular Velocity of Job or Workpiece - (Measured in Radian per Second) - Angular Velocity of Job or Workpiece is defined as the number of rotations the workpiece makes in a unit amount of time.

STEP 1: Convert Input(s) to Base Unit

Length of Cut: 9 Millimeter --> 0.009 Meter (Check conversion here)
Feed Rate: 0.7 Millimeter Per Revolution --> 0.0007 Meter Per Revolution (Check conversion here)
Angular Velocity of Job or Workpiece: 200 Revolution per Minute --> 20.9439510228654 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_m = L_cut/(f*N_v) --> 0.009/(0.0007*20.9439510228654)

Evaluating ... ...

t_m = 0.613883351957144

STEP 3: Convert Result to Output's Unit

0.613883351957144 Second --> No Conversion Required

FINAL ANSWER

0.613883351957144 ≈ 0.613883 Second <-- Machining Time
