XM series - Handheld Probe Coordinate Measuring Machine

Handheld Probe Coordinate Measuring Machine XM series

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 images showcases our latest XM-5000 model which allows high-accuracy measurement for palm-sized parts to large applications.


WM series - Wide Area Coordinate Measuring Machine

Wide Area Coordinate Measuring MachineWM series

The WM Series Coordinate Measuring Machine is a new handheld CMM designed accurate 3D and GD&T measurements over a large 15m (49 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.

Coordinate Measuring Machine (CMM) Parts

Typically, most CMMs are bridge or gantry-types as seen in the diagram. The spherical contact point attached to the tip of the probe is applied to the object on the stage, and the coordinate values in three dimensions (X, Y, Z) are specified and measured.
It is mainly used for three-dimensional measurement of dies such as automobile parts and various mechanical parts, three-dimensional objects such as prototypes, and measurement of differences from drawings.

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

Laser Cutting Machine

Laser cutting     is a fabrication process which employs a focused, high-powered   laser beam   to cut material into custom shapes and designs. This process is suitable for a wide range of materials, including metal, plastic, wood, gemstone, glass, and paper, and can produce precise, intricate, and complex parts without the need for custom-designed tooling. There are several different types of laser cutting available, including fusion cutting, oxidation cutting, and scribing. Each laser cutting process can produce parts with precision, accuracy, and high-quality edge finishes, and with generally less material contamination, physical damage, and waste than with other conventional cutting processes, such as mechanical cutting and waterjet cutting. However, while laser cutting demonstrates certain advantages over more conventional cutting processes, some manufacturing applications can be problematic, such as cutting reflective material or material requiring secondary ma...

 Biomechanical engineering is a field that integrates principles of mechanical engineering with biological systems, particularly focusing on the interaction between mechanical factors and living organisms. Here are some key aspects and applications of biomechanical engineering: Biomechanics : This involves the study of the mechanical aspects of biological systems, such as how forces affect cells, tissues, and organs. Biomechanical engineers apply principles from mechanics (statics, dynamics, fluid mechanics, etc.) to understand and analyze biological structures and functions. Medical Devices : Biomechanical engineers design and develop medical devices such as prosthetics, implants, orthotics, and assistive devices. These devices aim to improve mobility, enhance bodily functions, or replace damaged biological structures. Tissue Engineering : This field combines engineering principles with biology to create biological substitutes that restore, maintain, or improve tissue function. Bi...

Coordinate Measuring Machine Probes

Image
  A  Coordinate Measuring Machine  is defined by the ability of its probe. As with CMMs, there are several types of probes available. There is the contact probe, which measures the workpieces by making contact with them. The non-contact probe that employs lasers or machine vision probes which scan with optical sensors. Contact probes are a more accurate way of measuring. However, the laser or machine vision probes are far quicker to use, while still holding a high degree of accuracy. There are also multi-sensor probes which combine both touch and optical scanning, giving the benefit of both types in one probe. Coordinate Measuring Machines: Contact Probes The two most common contact probes are Touch Trigger Probes and Analog Scanning Probes. Touch Trigger Probes: A touch trigger probe has a stylus that is attached to a bearing plate. This is then connected to pressure sensors inside the housing of the probe. Each time the probe makes contact with the workpiece, it generat...
