Machining Time for Turning Operation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Turning Time = Length of Cut/(Feed Rate*Angular Velocity of Job or Workpiece)
t_m = L_cut/(f_r*ω)
This formula uses 4 Variables

Variables Used

Turning Time - (Measured in Second) - Turning time is the duration required to complete a turning operation on a workpiece in a lathe machine, from the start of cutting to the finish.
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 towards the workpiece 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_r*ω) --> 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 <-- Turning Time

(Calculation completed in 00.004 seconds)

Diameter of Workpiece given Constant for Cylindrical Turning

Go Diameter of Workpiece = Constant For Machining Condition*Feed/(pi*Length of Cut)

Turning Length given Constant for Cylindrical Turning

Go Length of Cut = Constant For Machining Condition*Feed/(pi*Diameter of Workpiece)

Feed given Constant for Cylindrical Turning

Go Feed = pi*Diameter of Workpiece*Length of Cut/Constant For Machining Condition

Constant for given Cylindrical Turning

Go Constant For Machining Condition = pi*Diameter of Workpiece*Length of Cut/Feed

Machining Time for Turning Operation Formula

Turning Time = Length of Cut/(Feed Rate*Angular Velocity of Job or Workpiece)
t_m = L_cut/(f_r*ω)

What is Turning Operation ?

Turning is the removal of metal from the outer diameter of a rotating cylindrical workpiece. Turning is used to reduce the diameter of the workpiece, usually to a specified dimension, and to produce a smooth finish on the metal.
