# CNC Radius Calculator Online

In the world of Computer Numerical Control (CNC) machining, precision is paramount. An essential tool that enables this accuracy is the CNC radius calculator, offering flawless measurements to craft perfect circles. This tool significantly contributes to the efficiency and effectiveness of CNC operations.

## Definition

A CNC radius calculator is a sophisticated digital tool designed to calculate the radius of a circle in a CNC operation. It determines the radius based on three distinct points located on the circle’s circumference. By reducing the chances of manual error, it increases the accuracy and consistency of CNC operations.

## How the CNC Radius Calculator Works

The CNC radius calculator utilizes a geometric approach, accepting the coordinates of three distinct points on the circumference of a circle. Through a series of computations involving distances and perpendicular bisectors, it determines the circle’s center. The distance between the center and any of the three points yields the circle’s radius.

## CNC Radius Calculation Formula

The CNC radius calculation process involves multiple steps, each step using a specific formula:

1. Calculate the distances between the three points A(x1, y1), B(x2, y2), and C(x3, y3):AB = sqrt((x2 – x1)² + (y2 – y1)²) BC = sqrt((x3 – x2)² + (y3 – y2)²) AC = sqrt((x3 – x1)² + (y3 – y1)²)
2. Find the midpoint of AB and BC, then calculate the slope of AB and BC, and their perpendicular slopes.
3. Find the equations of the perpendicular bisectors of AB and BC.
4. Solve the system of equations to find the center of the circle (x, y).
5. Calculate the radius as the distance from the center to any of the three points.
