Types of CMM

There are four basic types of stationary CMM:

• Bridge.
• Cantilever.
• Horizontal Arm.
• Gantry.

Bridge type CMM

BridgeCMMs are the most common type of coordinate measuring machine.

It is used for High accuracy, moderate flexibility, for medium sized components.

Cantilever CMM

Cantilever CMMsdiffer from the bridge-style in that the measuring head is…
