## Chamfer Diameter Calculator

Enter any 2 values to calculate the missing variable

The Chamfer Diameter Calculator is important when it comes to accurate measurement in manufacturing and engineering design. Our calculator lets you to measure chamfer diameter in length, radius and size by using the accurate formula. Moreover, in design engineering, chamfer angle calculator and countersink diameter calculators are also used in calculating the diameter in required figures.

**Formula:**

The formula is:

$\text{CD} = D – 2C$

Variables

Variable |
Meaning |
---|---|

CD | Chamfer Diameter (reduced diameter after chamfering) |

D | Original Diameter (before chamfering) |

C | Chamfer size (the width of the chamfer from the edge) |

**Solved Examples:**

**Example 1:**

**Given:**

- Original Diameter ($D$) = 10 mm
- Chamfer size ($C$) = 1 mm

Calculation |
Instructions |
---|---|

Step 1: CD = $D – 2$ |
Start with the formula. |

Step 2: CD = $10 – 2(1)$ |
Replace $D$ with 10 mm and $C$ with 1 mm. |

Step 3: CD = $10 – 2$ |
Multiply $2 \times 1$ to get 2 mm. |

Step 4: CD = 8 mm |
Subtract 2 mm from 10 mm to get the chamfer diameter. |

**Answer:** The chamfer diameter is **8 mm**.

**Example 2:**

**Given:**

- Original Diameter ($D$) = 20 mm
- Chamfer size ($C$) = 2 mm

Calculation |
Instructions |
---|---|

Step 1: CD = $D –$ |
Start with the formula. |

Step 2: CD = $20 – 2(2)$ |
Replace $D$ with 20 mm and $C$ with 2 mm. |

Step 3: CD = $20 – 4$ |
Multiply $2 \times 2$to get 4 mm. |

Step 4: CD = 16 mm |
Subtract 4 mm from 20 mm to get the chamfer diameter. |

**Answer:** The chamfer diameter is **16 mm**.

**What is Chamfer Diameter Calculator ?**

The Chamfer Diameter Calculator is very helpful that lets you to calculate the effective diameter of a part after a chamfer has been applied to it. In simple terms, the chamfer is a beveled edge that reduces sharpness and provides a smooth transition between two surfaces. It is often used in machining to remove sharp corners or edges.

The formula $\text{CD} = D – 2C$ calculates the diameter after the chamfer is applied by subtracting twice the chamfer size from the original diameter. It makes sure that the reduction in diameter due to the chamfer is accurately accounted for in the design or machining process.
