Nowadays, CMMs rely upon the position of the recorded probe points and the data coming from special software that calculates the position. When low-cost PCs were introduced into businesses in large numbers in the 1990s, geometric error compensation allowed for improving the accuracy of CMMs and reducing the cost of inspection. COORD3 introduced Silicon Carbide bases, which is stiffer and lighter and has better properties compared to granite, although this has not been universally adopted by manufacturers. However, the use of new probe types demanded a better structure as more forces are involved. This has barely changed at all in design or composition. The granite base still used by many large CMMs would be recognisable by the earliest machine operators. Another substantial innovation are measuring scales that increase the accuracy of the machine in all environments. It results in higher accuracy due to decreased deformation of the structure. Newer CMMs offer a lighter, more durable and tougher structure, and improve the dispersion of temperature changes. It is worth noting that all of these innovations to the CMMs are based on technology from outside of the industry. It has allowed operating a machine at higher acceleration levels and speeds. The introduction of the digital CNC controller has been used to deliver more accurate motion path and ensure circular motion paths instead of only straight lines. Newer CMMs made use of lighter synthetic materials rather than traditional steel and granite designs. Their mechanical structure has improved, making them lighter with better repeatability. Hardware Innovations Post 1980sĮven though CMM parts evolved dramatically between 19, the core technology behind coordinate measurement has been comparatively static for the last 30 years. Further innovations included automatic probe changing racks, affordable scanning probes, and automatic probe stylus evolution. Renishaw changed the performance capabilities of CMMs once again in the early 1980s, when the motorised probe head was introduced. This device has changed the measurement process of parts and played a huge role in the globalisation of CMMs. With a touch probe, it’s possible to generate automatic measuring points on the surface while recoding the XYZ position in space of the taken point. It uses discrete points to show the size and position with high precision. The CMM can read the touch probe input, as pre-set by software or by the operator.

Every axis has a scale system that shows its position relative to other points. 3-Axis, 3D SystemsĪ classic CMM has an X, Y, and Z axis and operates in a 3D system. This invention resulted in a revolution of 3D measurement, opening the world up to accurate and automatic measurements of separate components and entire assemblies. The co-founder of Renishaw, Sir David McMurtry, invented the Touch Trigger Probe in 1970, which enabled the Olympus engines used in Concorde aircrafts to pass specific requirements. After this their use by businesses of all sizes quickly gathered pace. Several big companies from the most developed countries of that time, including the USA, Japan, Germany, and France joined in the production of commercial CMMs during the 1960s. They were manufactured by Ferranti, a British company that also developed the first commercial computer for a general audience in 1951.

The history of CMMs started in 1959 when they first appeared at the International Machine Tool Exhibition in Paris. As ubiquitous as CMMs now are in manufacturing, it is hard to imagine a world when quality control was dependent on hand measurements. These CMMs can be Manual, where an operator guides the machine, CNC machines that are driven automatically by a special program. The modern CMM industry produces over 6,000 new CMMs every year, as well as retrofitting and upgrading tens of thousands more. Coordinate Measurement Machines have an interesting history going back almost 60 years.
