# Turning Operation, Process Calculations with a Calculator

In the industry, turning operation is extensively used to produce different kinds of parts and components. Like other manufacturing processes, strict calculations are required. You can use the calculator below to make the necessary calculations for turning operations.

## Turning Operation Calculator

You can use the turning operation calculator below to calculate all the parameters required to complete the turning operation.

## Turning Operation Calculator

The use of the turning operation calculator is very simple above. You just need to enter the original diameter of the part, cutting speed, depth of cut in the turning operation, feed, and length of the part. After entering these values click on the ‘Calculate!’ button to calculate the required parameters related to the turning operation. If you want to make further calculations, just click on the ‘Reset’ button then re-enter the required values again.

The turning operation calculator is very useful for the process designer. You can calculate all the turning process parameters in one shot. You can make successive calculations to obtain optimized values.

In this calculator, the units of the entered parameters related to the turning operation,

v: cutting speed = m/min or ft/min

Do: original diameter = m or ft

d: depth of cut = m or ft

f: feed = mm/rev

L: length of workpart = mm or in

## What Turning Operation Calculator Calculates?

With the turning operation calculator, you are calculating;

### Rotational Speed of Turning Operation

‘N’ is the rotational speed which has the unit of rev/min. The equation is;

In this formula, ‘v’ is the cutting speed, m/min or ft/min, and the original diameter of the part ‘Do’ which has the unit of m or it must be entered. The rotational speed is directly proportional to the cutting speed and inversely proportional to the original diameter.

### Final Diameter of the Work Part

‘Df’ is the final diameter of the work part after the turning operation is applied. The unit of the final diameter of the part is mm or in. The final diameter is calculated like this;

The final diameter ‘Df’ is calculated with the original diameter and the depth of cut which has the unit of m or in. With the increasing depth of cut, the speed of decrement of the diameter increases.

### Feed Rate of Turning Operation

‘Fr’ is the feed rate in the turning operation which gives the linear progression of the tool along the length of the part. The unit is mm/min or in/min. The feed rate is calculated like this for turning operations;

To calculate the feed rate, rotational speed and the feed must be entered inside the formula. Here the unit of the feed(f) is the mm/rev or in/rev that shows how much the turning tool progresses in each revolution. With the increasing rotational speed and the feed, the total feed rate of the turning operation increases.

### Total Machining Time of Turning Operation

‘Tm’ total machining time which is the total time that is consumed in the total machining operation. The total machining time or total turning time is calculated with the formula;

In this equation, you need to enter the original diameter, length of the part in mm or the feed, and the cutting speed. According to the turning time, turning time increases with the increasing original diameter and length and decreases with the feed and the cutting speed.

### Material Removal Rate of Turning Operation

‘Rmr’ is the material removal rate in the turning operation which has the unit of mm^3/min or in^3/min. It shows the total material removal in volume through the turning operation. The material removal is calculated like this;

To calculate the material removal rate, the cutting speed, feed, and depth of cut must be defined. The material removal rate is directly proportional to the three parameters.

## Conclusion

The turning operation calculator is very simple to use and very useful as you see above.
