The Keyence VR Series 3D profilometer measures shape, contours and roughness in just seconds. According to Keyence, "This wide-field 3D measurement system drastically changes the conventional working techniques of quality and metrology departments. Surface acquisition becomes simpler, more reliable and faster, and above all, the analysis of the results is greatly facilitated thanks to the powerful and intuitive tool panel. Simply place the part on the stage and the surface is scanned and measured in just 1 second."
In general, surface analysis performed with contact measuring machines (CMMs, contact profilers, roughness meters...) is time consuming and partial because of the limited number of probed points.
Built around an innovative optical technology, the VR-5000's approach is to scan, without contact, the entire surface to be analyzed, allowing to model it in 3D with a very high resolution. No preparation of the part is necessary, it is enough to put it down and to launch the measurement. In addition to the productivity gain, the VR-5000 offers a reproducibility of the measurement conditions. Finally, since the measurement is non-contact, parts with protruding shapes or made of flexible materials (rubber, silicone, elastomer...) or with fragile surfaces are not an obstacle for the VR-5000.
Innovations
The main innovation is the lighting system that projects a multitude of bangs deformed by the topography of the surface to be analyzed. These deformations are then analyzed by triangulation in order to determine the altitude of each point on the surface.
In addition, the VR-5000 features a telecentric lens, a technology that Keyence has long mastered. This lens provides a large depth of field while eliminating the effects of parallax. This eliminates the need to worry about focusing, even when the part to be analyzed has significant differences in height. Finally, the absence of aberrations and distortion guarantees a faithful reproduction of the dimensions of the part for an increased accuracy of measurement.
Manipulation within reach of all
The VR-5000 automatically adjusts to the orientation and tilt of the object. Simply place the target on the stage and click a button to start the measurement process.
It automatically detects the width and height of the target to automatically set the optimal measurement range.
In addition, the VR-5000 automatically detects a reference plane, the axis of a cylinder, the intersection between two planes or the center of a sphere in order to position the image of the part in space. The initial alignment of the part, a long, tedious and error-prone process, becomes totally superfluous.
The VR-5000 includes a set of automatic functions for part analysis. In addition to profile measurement, it can also analyze line and surface roughness.
The tool panel also includes functions for 2D measurement, flatness or co-planarity defects, volumes and areas.
Finally, the comparison function allows to quickly detect discrepancies between a reference part (compliant) or a 3D CAD model and a defective part. The investigation can then be focused on the suspect areas.
In addition, as with the entire Keyence metrology range, statistical tools for production control (Cp, CpK, trend curves and histograms) are available, as well as the production of automatic or customizable measurement reports.
Simplified calibration
The VR-5000 comes with a set of standards linked to the international traceability system. The user can thus proceed independently to the calibration and recalibration of his machine in compliance with the requirements of ISO-17025.
The procedure, extremely simple and guided, allows you to perform the operation alone in a few minutes. Beyond the time saved, this represents a substantial saving on the annual costs related to the usual maintenance contracts.
The VR Series is suitable for quality control in metallurgy (machined or stamped parts including special parts such as screws, cutting tools, drills), plastics and elastomers, but also electrical and electronic components, medical devices, and food packaging.
