**MITER BEND FORMULA**: **hey guys in this post I have taught about miter bend formula in easy way as you can see in below images.**

**The formula for miter bend cutting **

**CF × Cut Degree/360° × Number of Cut × 2**

**STEP 1..** **First of al**l **ensure the pipe diameter and then find out their Circumference.**

**the formula for finding** **circumference = outer diameter x 3.142 (the value of pie)**

so, **CF = OD x 3.142**

**CF = 168 x 3.142 = 527.85 mm**

**STEP 2.. Now After calculating the CF divide it by center line.**

** depend up on your choice how ever I am suggesting you to make it in eight center line.**

**lets start to make in eight center line in the pipe **

so, **OD = 168 mm**

and, **CF = 168 x 3.142 = 527.85 mm**

Now, **divide by center line**

So,**527.85/8 = 65 mm **

Now, **let it mark in surrounding of pipe as shown in figure**

**STEP 3..**

**Now, Calculate the CUTBACK and MIDDLE and SIDE PCS length. **

**for calculating the cutback use this Formula = **

So, **CF × Cut Degree/360° × Number of Cut × 2**

**= 527.85 x 90°/360° x 3 x 2**

**so**,** 47506.5/2160**

**So, 21.99 mm Cutback.**

**Now i am going to multiply it by 4 because i am going to make this elbow in short radius.**

**21.99 × 4 = 87.96 mm this is Middle Piece Length.**

**Now we will divide it by 2 for side piece length** **87.96/2 = 43.98 mm**

**Mark the Cutback in Pipe as Shown in below image**
