Process foundation Component quality is dependent on machine performance. Without understanding the errors in a machine it is impossible to have confidence that your components will meet specification. Accurate measurement and set-up of machines is the foundation of process control, providing the best performance and stable environment for the machining process. Quantifying process capability reduces costs and improves efficiency.

Laser interferometry provides the most accurate and repeatable method of calibration, offering solutions for a wide range of applications. Machine verification Specialist laser triggering The XL-80 laser system is primarily used for the verification of motion systems. Measuring machine performance allows users to be confident in their machining or identify issues before they are seen in manufactured parts. Some applications require the laser to capture data at custom times or synchronised locations. This can be achieved with the CARTO software suite’s Capture application using the keypress, position...

Dual axis Laboratory applications In some installations, one axis of a machine is controlled by two drives and two feedback systems (for example, spar mills, lathes and large gantry type CMMs). In this instance, two laser set-ups coupled with dual axis software provide the capability to automatically capture data of parallel axes simultaneously. The XL-80 laser has become the system of choice for a variety of laboratory applications since its introduction, including in many of the world’s prestigious calibration houses. Its ultra-stable laser frequency, published error budgets, and unbroken path...

Now, we are very well organised and using the Renishaw equipment means we know much more about our machines and our processes. We’re always looking for ways to do things better. Our performance standard is zero defects, which is the third absolute in our quality philosophy. Nothing leaves this machine shop unless it is exactly right, but we couldn’t do it without Renishaw. FMC Technologies (United Kingdom) We have found many benefits using Renishaw’s XL-80 laser. It is easy to operate, has fast set-up and user-friendly software with an intuitive interface. Compared to the laser brand we used...

System overview XL-80 laser XL-80 laser Accurate – an extremely stable laser frequency that is traceable to national and international standards. The XL-80 laser has an integrated USB port. The laser features an auxiliary analogue signal output as standard, with quadrature output as a factory option. The Aux I/O socket accepts a trigger signal input for remote triggering. The XL-80 quadrature laser is subject to export control regulations. Note: XL-80 lasers with quadrature output should not be used in a feedback system.

Renishaw calibrations are traceable to signatories of the CIPM MRA, which provides consistent measurement standards around the world Convenient to align Lightweight optics and a comprehensive range of quick fixturing solutions. Optics give nonoverlapping output and...

XL-80 measurement types Linear measurement his is the most common form of T measurement performed with a laser. When performing linear measurement the XL-80 laser measures the change in relative distance between a reference and measurement optical path. Either optic can be moving, providing one remains stationary. The XL-80 laser system provides accuracy performance of ±0.5 ppm with a resolution of 1 nanometre. A long range linear kit is available for 40 m to 80 m applications. Angular measurement Angular measurements are made by monitoring the change in optical path generated between a fixed...

Squareness measurement his measurement determines T the perpendicularity of two nominally orthogonal linear axes. Squareness errors could be the result of movement in machine foundations, misalignment of home position sensors (on gantry machines) or poor build control. They will directly impact the geometry of parts produced by this machine. The squareness between two axes can be calculated using a calibrated optical square and combining two straightness measurements. To complete a squareness measurement involving the vertical axis, additional optical accessories will be required. Flatness measurement...

The optics mounting kit is used to mount the measurement optics to the machine under test in a variety of set-ups. 2 Magnetic base The magnetic base is used for mounting the optics or the XL-80 laser (when used in combination with the XL magnetic base adaptor). The base features an on/off switch for quick mounting and a female M8 fixing thread. The supplied kit contains 2 bases. 3 Large retroreflector The large retroreflector is used for straightness and squareness measurements involving the vertical axis of the machine. 4 Straightness base The straightness base is designed to mount the straightness...

The pan and tilt adaptor kit is designed to allow flexible mounting of laser calibration equipment at angles between 0° to 90° with an infinite pan rotation. 11 Long range linear optics kit Over long distances a laser beam diverges. Outgoing and incoming laser beams may interfere with one another. The long range linear kit includes a periscope to separate the beams and a large retroreflector to maintain separation. The target provided makes alignment easier and allows for measurements of between 40 m and 80 m. 12 Small linear optics kit The small linear optics kit allows an XL-80 laser system...
