The miter saw is a circular saw mounted to a mechanical arm that allows it to travel smoothly in the plane of the cut.  It can tilt up and down and it can move in and out from a fixed column in the back.  As such, it is less constrained than a radial-arm saw but more constrained than a hand-held circular saw.  The workpiece is held firmly against a fence in the back of the machine and the saw cuts from the front to the back.  The saw can be rotated with respect to the fence to do "miter" cutting.  The blade can also be tilted laterally to make "bevel" and "compound" cuts.

The miter saw is a circular saw mounted to a mechanical arm that allows it to travel smoothly in the plane of the cut. It can tilt up and down and it can move in and out from a fixed column in the back. As such, it is less constrained than a radial-arm saw but more constrained than a hand-held circular saw. The workpiece is held firmly against a fence in the back of the machine and the saw cuts from the front to the back. The saw can be rotated with respect to the fence to do "miter" cutting. The blade can also be tilted laterally to make "bevel" and "compound" cuts.
