CMM / Laser Tracker
Our portable coordinate measuring machines allow anyone to easily measure 3D/GD&T features, compare to CAD, and automatically generate detailed inspection reports anywhere, including the shop floor. The handheld probe allows for the ease and full-range of motion of hand tools, while providing the capabilities and accuracy of a CMM. Along with no required CNC programming and no moving parts, our CMMs provide significant accessibility for companies with no previous CMM experience, or looking for complementary tool to reduce inspection bottlenecks.
The XM Series is a handheld coordinate measuring machine (CMM) that lets anyone easily measure 3D/GD&T features. The system is portable and shop-floor ready, so measurements can be taken in any location. The unit also automatically records measurement data and creates detailed inspection reports. The image showcases our latest XM-T2200 model which has a measurement area for up to 3' parts as well as a newly-developed rotational XΘ stage to easily approach parts without having to move and fixture the piece.
The WM Series Wide-Area Coordinate Measuring Machine is a new handheld CMM designed accurate 3D and GD&T measurements over a large 10m (32 ft) area. Similar to the XM Series, the unit is portable and shop-floor ready, so measurements can be taken in any location including in the machine tool. The unit also automatically records measurement data and creates detailed inspection reports. The image showcases our latest WM-3000 model which uses a wireless, handheld probe with on-screen visual guidance to have a single operator easily inspect parts with complex dimensions or would normally require multiple inspectors due to part size.
A coordinate measuring machine (CMM) is a measuring device that measures the geometry of objects by establishing discrete points on a physical surface using a contact probe. The machine will specify the probe's position in terms of displacement from an origin point in a three-dimensional coordinate system (XYZ axes). A CMM can measure critical 3D dimensions with high-accuracy, record the measured data and obtain complex GD&T features. Non-contact models use other methods such as cameras and lasers.
Benefits of Coordinate Measuring Machines (CMMs)
Coordinate measuring machines (CMMs) have three-dimensional measurement capabilities (X, Y, and Z directions), unlike hand tools such as micrometers, vernier calipers, or height/depth gauges, which are limited to measurement in only one direction at a time.
CMMs accurately track a probe tip in 3D space and create dimensional measurements through shape building via the points taken through contact with the measurement piece. An even greater number of points can be taken over a larger area on the part to map the surface and compare to CAD data for shape, form, and warpage inspection.
A powerful advantage of coordinate measuring machines (CMMs) is that they can measure items that are difficult to measure with other measuring machines to a high degree of accuracy.
Another feature that stems from the CNC nature of the measurement system, is the ability to measure the three-dimensional coordinates of a specific point (a hole, etc.) from the virtual origin with a hand tool such as a caliper or micrometer. Also, measurement using virtual points and virtual lines and geometrical tolerances are difficult with other measuring machines but can be measured with a 3D CMM machine.
Coordinate measuring machines (CMMs) are automated inspection tools. Skilled programmers create a measurement routine or program by measuring any required 3D or GD&T dimensions on a part.
Once the program is registered and an origin point is established through a coordinate system, parts can then be fixtured in place and operators can have the coordinate measuring machine run an automated measurement procedure. While there is a good amount of time invested in the program creation, the actual part inspection can be left to run automatically.

Frequently Asked Questions About Coordinate Measuring Machines (CMMs)
Coordinate measuring machines (CMMs) are intricate inspection tools with many moving parts, temperature and humidity sensitive components, and various fragile items. This makes the harsh production environments where there's a much higher potential for costly damage or nonoptimal measurement conditions leading to inaccuracies during the inspection. Quality labs are designed to be safe zones, environmentally regulated, and provides favorable conditions for proper inspection.
KEYENCE's XM Series handheld coordinate measuring machine is a portable, shop floor Coordinate measuring machine (CMM) designed to enable any user to easily and accurately measure 3D and GDT features, anywhere. Once the part is measured, the system automatically records the data and creates an inspection report. Our latest unit allows for CAD comparison and 3D CAD export. When compared to a traditional Coordinate measuring machine (CMM), companies see a significant reduction in inspection time and increased throughput through shop floor checks by anyone and helping to eliminate any Coordinate measuring machine (CMM) backlog.
