Apr 9, 2025 · What is the principle of CMM? The principle of a Coordinate Measuring Machine (CMM) is based on 3D coordinate measurement using a probe system. It records the precise X, Y, and Z coordinates of an object’s surface to determine dimensional accuracy, ensuring compliance with design specifications.
The coordinate measuring machine (CMM) is a mechanical system that moves a measuring probe to determine the coordinates of points on the surface of a workpiece.
Dec 4, 2020 · Fixed Probe Heads: Fixed probe heads are, as the name implies, are fixed pointing downwards in the Z minus direction on a CMM. These probes are specifically economic when you measure parts that are flat and only require you to use the XY Plane.
Dec 4, 2024 · The part that is to be measured is placed on the CMM’s base. The base is the site of measurement, and it comes from a dense material that is stable and rigid.
May 9, 2019 · Displacement measuring CMM probes are also known as scanning probes. This method generally involves passing the prob over a target surface at its working range. As the probe scans the surface, it transmits the continuous flow of data to the measurement system.
Feb 4, 2019 · There are several different types of CMM’s, such as bridge, gantry, horizontal arm, articulated arm, and cantilever. However, they all consist of the same basic components: a base, a computer, and a touch probe. The base of a CMM acts as a table for the part to be measured.
Dec 9, 2020 · Fixed Probe Heads: Fixed probe heads are, as the name implies, are fixed pointing downwards in the Z minus direction on a CMM. These probes are specifically economic when you measure parts that are flat and only require you to use the XY Plane.
Jan 18, 2021 · These compact, versatile CMM’s consist of a vertical post with multiple articulating segments and up to 8 axes of movement. A probe is mounted to an articulating joint at the end of the arm, and they often have a laser scanning apparatus allowing for …
The probe has two normal operating states, armed or triggered. The probe should be in the armed state except for the moments when the stylus is deflected against the workpiece.
May 9, 2023 · What the probe calibration is doing is teaching the CMM where the center of the probe tip is in relation to the head. Once that is known, the CMM knows where the probe tips are.
