Koordinátamérgépek

Koordinátamérgépek, otherwise known as coordinate measuring machines (CMMs), are precision engineering devices used to determine the physical geometrical characteristics of an object. By using a probe that contacts the workpiece and a computer to record the probe’s position, a CMM can measure linear dimensions, angles, and surface contours with a typical accuracy ranging from a few micrometers to sub‑micrometer levels.

The basic operating principle involves a coordinate system – usually defined by three mutually perpendicular axes – in which the probe moves and records data points. Modern CMMs may be tabletop, bridge, or gantry configured to accommodate different size ranges and production environments. In addition to mechanical probing, optical, laser, and ultrasonic sensors are also employed, providing non‑contact alternatives for delicate or hazardous materials.

CMMs are integral to quality inspection in aerospace, automotive, medical device, tooling, and semiconductor industries, where stringent dimensional tolerances are mandatory. They can verify parts against design specifications, perform statistical process control, and document as‑built data for future reference. Measurement data is often exported to CAD/CAM systems, enabling rapid feedback in the manufacturing cycle.

The first mechanical CMMs appeared in the 1960s, with Pasco Gains beautiful. Since then, advances in computer technology, machine kinematics, and sensor development have significantly increased measurement speed, ease of use, and data fidelity. Many modern systems feature automated probing, integrated machine vision, and cloud‑enabled data acquisition, further streamlining design‑to‑production flows.

Overall, koordinátamérgépek remain a cornerstone of precision manufacturing, providing reliable, repeatable measurements that support product integrity, certification, and continuous improvement.
