Types of cmm 3d coordinate measuring machine
Meeting the needs in various sectors require CMMs to be 3D coordinate measuring machines. These devices exist in many types. Each differs in how it shines light on, accuracy, flexibility, and features suitable for tasks in measuring. The main kinds of CMMs are discussed below:
Bridge CMMs
Thanks to their simple structure, bridge CMMs are the most common type of CMM. These machines have a bridge-like framework above the working area. The probe movement is controlled on three axes, commonly known as X, Y, and Z. They are one of the dimension measuring equipment suitable for general measurement with an allocation of accuracy. Moreover, they are perfect for a shop floor where bigger parts are measured. Those common features include:
- Accuracy: Bridge CMMs offer high accuracy, making them ideal for measuring medium to large-sized parts.
- Usability: Their straightforward design and user-friendly interfaces.
- Versatility: They support a range of probes and measuring tools for different materials.
Horizontal CMMs
Unlike bridge CMMs, horizontal coordinate measuring machines are mainly structured to work more effectively on a horizontal plane. They are largely used in measuring cylindrical and disk-shaped products like shafts and gears. Key features include:
- Orientation: The horizontal layout is perfect for measuring rotated parts, providing easy access from multiple angles.
- Measurement of Specialized Parts: Especially suited for parts with cylindrical features, making it ideal for gears, shafts, and other rotational components.
Vertical CMMs
Vertical CMMs operate precisely and are better on vertical measuring. As opposed to the bridge style, the probe's movement is measured along two horizontal axes with one vertical axis. These machines are well used in smaller, detailed metric parts. The following are the features that can be highlighted:
- Detail Measurement: Their vertical design makes them excellent for small parts and intricate geometries.
- Their vertical design minimizes floor space, making them ideal for environments with limited room.
Scanners CMMs
Scanner CMMs are developed to enable probe contact. This probe continuously scans the surface of the parts. A scanner CMM is beneficial for complex surface measuring where exact coordinates are needed. Notable features include:
- Surfacae Mapping: The ability to capture surface data makes them perfect for industries such as aerospace, automotive, and molds.
- Technology: Laser scanning probes enable the capturing of surface profiles in 3D, enhancing the precision of complex shapes.
