How Does a 5 Axis CNC Machine Work?

What Is a 5 Axis CNC Machine?

A 5-axis CNC (Computer Numerical Control) machine is an advanced machining tool capable of moving a cutting tool or workpiece along five different axes simultaneously. Unlike traditional 3-axis machines, which operate along the X, Y, and Z linear axes, a 5-axis machine adds two rotational axes (A and B or C) for greater flexibility and precision.
