Hexagon's Manufacturing Intelligence division has launched a wireless multisensor laser scanner offering metrological precision and specially designed for applications on CNC machine tools.
The LS-R-4.8 m-h, which can raise about 40,000 points per second, is an alternative to traditional feelers measuring individual points. It transmits data securely to the receiver via a radio link, allowing users to automatically switch the machine's sensors without manual intervention.
Whether done to control the machined part, temperature or tool, machine tool measurements are a valuable source of information during the machining process. The data obtained is used to verify parts before or during machining. They thus help to guarantee the quality of the products and optimize the manufacture, for example through an automatic alignment of the parts. These small improvements add up and increase production efficiency.
The wireless scanner removes bottlenecks with built-in measures that allow for an immediate improvement in the machining of CNC machine tools. In modern manufacturing units, production often has to be stopped until results are available. This new wireless laser scanner performs quick measurements on the machine tool itself, and sends the results quickly to the relevant stations, for example to quality engineers or manufacturing managers.
With 40,000 points per s, the instrument provides information about the entire piece, rather than selected individual points. This allows users to assess manufacturing quality, optimize production processes by identifying problems at an early stage, better align parts for the next steps, and obtain information on the quality of complete parts. "Wireless connectivity allows you to do these measurements without removing the part from the machine and without using external mobile measurement tools - which would take a long time," says Product Marketing Manager.
The increase in overtime and the best performance offered by the scanner is particularly important in areas where many machines are used for sequential manufacturing operations. The parts must be placed precisely to ensure precise milling. "The laser increases performance by raising the entire surface of the room instantly, while conventional methods slowly measure many individual points. It is much longer to measure parts with manual systems between the different stages than to use a built-in laser scanner. »
The wireless scanner is based on laser triangulation to provide a high level of speed and accuracy. The laser beam is projected onto the component, and the reflected beam passes through a lens, where it is detected by an imager. Position measurement points are determined using this information.
Specialized modular software presents the data in an explicit format, allowing machine operators and quality assurance teams to quickly identify quality issues and properly align a part to correct it while it is attached to the machine tool. The large amount of data provided by machine tool laser scanning offers new optimization possibilities for machine manufacturers and operators:
- Creating color images that overlay the jammed piece on the source CAD model to identify discrepancies
- Measuring free geometry surfaces with up to five axes, ensuring that virtually any part of the component is recorded
- Scan a part while it is on the machine tool, export an STL file to the CAD system, create a cloud of points for retrodesign, for example with Hexagon's REcreate software.
- Generating correction values using a "Best-Fit" software module, which can be loaded into the machine control for an automatic adjustment of the part.
The new pack contains the wireless scanner, modular software and the RC-R-100 multisensor receiver. The scanner is stored directly in the tool store inside the CNC machine and is inserted into the pin automatically without any manual intervention.
Working primarily with machine tool companies, enabling them to add value to their customers, Hexagon provides a solution that can be used on multiple machines from different machine tool manufacturers. The laser is part of a wide range of Hexagon measurement systems that transform a machine tool of any brand into multi-sensor equipment. For example, separate feelers can measure the temperature and thickness of the wall. Now the laser is taking up all the surface data.
The equipment works with a single receiver, and Manuel Muller says that wireless technology switches sensors instantly: "We work with manufacturers with multiple sensors on their machines, and these sensors can be switched automatically and easily in applications, depending on the user's program."
