Our service engineers have extensive knowledge of how CMM’s are built and work, ensuring your system’s needs will be in good hands. Our services include installation, relocation, service, support, retrofits, training, turnkey programming, and calibration.

The Importance of CMM Calibration

One of the most advanced, accurate dimensional measurement devices is the CMM. To maintain its refined measurement abilities, a CMM should be calibrated at a frequency of at least once a year. Calibration involves verifying and adjusting the CMM and related equipment to a certain standard. CMM calibration ensures the machine is meeting measurement standards with consistency and accuracy. In the calibration process, the CMM measures verified artifacts in certain orientations to prove that measurements are accurate.

A CMM probe performance test is primarily done to ensure the probe remains accurate and repeatable.. This test can provide feedback on the condition of the probing system to better understand if there are potential issues that typically don’t present themselves during normal use.

Like any measuring device, a CMM will have a certain amount of uncertainty with its measurements. Most modern CMMs have tolerances at the micron level. With frequent use, measurement readings can grow or shrink beyond that base accuracy. Regular preventative maintenance and recalibration ensures that the accuracy expectations remain consistent.

Featured Calibration Services

A good CMM calibration will include multiple inspections and scheduled maintenance. All of our calibration services include:

  • Clean and inspect X, Y, and Z scales: Cleaning the scales is often the first step in any calibration process. This enables a complete and accurate inspection.
  • Inspect beam/plate parallelism: Checking the beam is parallel to the CMM’s working surface is the next step. Adjustments are made as needed.
  • Inspect X, Y, and Z fine adjustment: The fine adjustment devices naturally endure a certain degree of wear over time. If that is the case, the mechanisms will need to be tightened to ensure reliable measurements in the future.
  • Inspect linearity: Most CMM machines use a high-performance motor. These motors move the CMM frame in a linear motion, so the X, Y, and Z axes must be checked and adjusted as needed.
  • Inspect perpendicularity: Calibrating a CMM’s perpendicularity involves placing a stylus on various points of the surface plate and the L-shaped target, or the measurement plane. Adjustments are made accordingly.
  • Check reader heads: An oscilloscope is used to check the reader heads of each axis. Heads are adjusted as needed to ensure the best possible output.
  • Check for repeatability in X, Y, and Z axes: An electronic touch probe is used to check each axis for repeatability.
  • Test volumetric ball bar performance: ASME B89.4.1—which entails CMM calibration standards—establishes the recommended ball bar positions that this test will check for.
  • Calibrate the CMM for accuracy conformance: Volumetric accuracy testing is performed to the ISO 10360 standard utilizing the 7 orientations of the certified length artifacts.
  • Issue calibration certificate: At the end of the calibration, an official ISO/IEC 17025:2017 certificate is issued for the CMM. All readings are documented using a NIST traceability number.
