What is a three-dimensional measurement?
Volume is a three-dimensional measurement; that is, it measures the combined length, width, and height of a figure. Because planes, polygons, and other two-dimensional figures don’t have height, they have no volume. Only solids and figures with dimension greater than or equal to three have volume.
What are CMM machines used for?
Geometry
Coordinate-measuring machine/Calculation supported
A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, including mechanical, optical, laser, and white light.
Which of the following is provided as a scale in three-dimensional measuring machines?
Which of the following is provided as scales in three dimensional measuring machines? Explanation: Laser interferometers are provided as scales in three dimensional measuring machines. A cooling system is also provided in this machine.
What is portable CMM?
Portable CMM is a device for collecting measurements off the surface geometry of an object. Each time you touch the surface of an object with the probe it collects one measurement point, or a 3D coordinate (XYZ).
How much does a portable CMM cost?
Portable CMMs have traditionally been priced in the $30,000 to $50,000 range.
How does a CMM machine work?
A coordinate measuring machine (CMM) works in much the same way as your finger when it traces map coordinates; its three axes form the machine’s coordinate system. Instead of a finger, the CMM uses a probe to measure points on a workpiece. Each point on the workpiece is unique to the machine’s coordinate system.
How many types of CMM machines are there?
four
There are four main types of coordinate measuring machine (CMMs): bridge, cantilever, gantry and horizontal arm. The one you choose will be determined by what you wish to use it for. All CMMs have three orthogonal axes, X, Y and Z which operate in a 3D coordinate system.
Which of the following is a three-dimensional scale?
Answer: globe is a three-dimensional scale model of Earth, the only geographical representation suffering no distortion.
