The History and Evolution of Coordinate Measuring Machine CMM Controllers
Computer numerical control (CNC) is a method for automating the control of machine tools by using dedicated hardware, software and microcomputers. It is commonly used in manufacturing for machining parts and measuring them, through the execution of a part program containing the instructions and parameters the machine tool or probe will follow, such as the feed rate and the axes speed and position.
The Difference Between a Certified Preowned and a Used CMM
Hexagon Manufacturing Intelligence Preowned CMM division's goal is to take the "used" feeling out of the used CMM buying experience. We don't believe in bait-and-switch tactics, selling old software or computers, and not backing up each and every purchase with parts and service availability, technical support, training and a warranty.
Laser tracker technology continues to advance, offering more capabilities and functionality than ever. This video shows advancements in laser tracker probing technology such as the Leica B-Probe, and Leica T-Scan 5 and discusses how tracker-machine automation is becoming a go-to technology in many industries that require independent positioning control and feedback for industrial robots.
Measurement Technologies Step Up to Production Machining Needs
With the evolution of this machinery and their related processes, manufacturers of high-to-medium volume turned parts are facing increased inspection requirements in terms of frequency, feature measurement, and production statistics, as well as rising accuracy specifications.
Model Based Definition Promises Big Dividends for Quality Assurance
In the long evolution of 3D CAD, you would not think innovative progress is possible at this point. Take Model Based Definition, or MBD, a term and methodology long tossed around by software developers and the aerospace industry.
Tube and pipe bending shops are a rare breed in the manufacturing industry and they face important challenges exclusive to their discipline. Measuring the very tubes and pipes they bend is one such challenge. In this industry, accuracy counts. A tube that does not meet specifications will likely head to the scrap bin, as it won’t have the proper clearance to mate-up and connect with subcomponents. Market forces demanding tighter tolerances and better costs are forcing tube and pipe benders to rethink their processes and improve accuracies as well. Advancements in measurement technology designed specifically for this application can increase productivity and precision while dramatically reducing scrap rates.
The Hexagon Metrology Special Systems Group (SSG) is a dedicated team within Hexagon Metrology that does design, system integration and project management for custom and semi-custom integrations of coordinate metrology products with other manufacturing technology.
Leica Geosystems was the first laser tracker manufacturer to put an ADM into a laser tracker. The introduction of the LTD500 in 1995 revolutionized the way that laser trackers were used. If the beam was interrupted the operator no longer had to return to a known location to “reset” the IFM distance.
Coordinate Measuring Machine Accuracy on the Shop Floor
Coordinate measuring machine (CMM) accuracy is dependent upon the ambient thermal environment in which it operates. Changes in temperature cause the scales, machine structure and artifacts being measured to expand, contract, and, in some cases, distort in a non-linear manner.
Gear Inspection with Leitz Coordinate Measuring Machines
CMMs, when properly equipped, are the ideal tool for measuring gears. They combine the flexiblity of a general purpose measuring system, with specialized probing and software that allows them to be fully functional gear measuring centers.
Few could have guessed that chewing gum would usher in an era of streamlined production, reduced costs, and unparalleled traceability. However, in June 1974, a 10 pack of Wrigley’s Juicy Fruit did just that as it became the first product scanned with a universal product code (UPC).
