Automated in-line dimension measurement

Nikon Metrology has added two new models to its Nexiv S-range of CNC video measuring systems, which are suitable for in-line, automated dimensional measurement tasks. The latest systems can automatically measure the dimensions of component features using Nikon’s optical and image processing technology. By analysing the captured image of a component, detecting feature edges at high speed accurately and repeatably, it is possible to quickly measure components with simple or complex features.

In November 2020, Nikon released the first in its line-up of new VMZ-S systems, the VMZ-S3020, which is part of the fourth generation of the series. Today, the VMZ-S4540 and VMZ-S6555 join and expand this line-up and are solutions for inspecting medium and large components, or multiple smaller components. Now that the full line-up is available, it is possible to select the most suitable machine according to a customer’s applications and installation environment.

Nexiv systems achieve high measurement accuracy using a stage featuring high-precision linear encoders. The Nexiv VMZ-S series is capable of capturing and processing images at higher speeds than the predecessor range. This advance has made it possible to reduce component measurement times without compromising accuracy or reproducibility.

Nikon has designed an optimised optical system to deliver high-quality images and acquire accurate measurement data from within the field of view. With a movable LED ring light and eight-segment LED illumination, users can resolve and capture the edges of complex shapes. In addition, a high-speed laser scanning at 1000 points per second is able to acquire the cross-sectional profile over a surface and evaluate the relative heights. This capability meets surface quality and feature measurement needs across a variety of samples.

Mitutoyo solution aids inspection efficiency

The recent installation of a turnkey CMM solution at Tecomet Sheffield, illustrates the design and build capabilities of Mitutoyo Gauging Technology (MGT), a specialist division of Mitutoyo. Throughout the project, MGT worked closely with Mitutoyo’s dedicated subcontract measurement department – Measurement Services.

Based on a Mitutoyo MiStar shop-floor CMM, the resulting inspection system allows the rapid, accurate and automated dimensional inspection of a range of femoral knee joints. Using custom-built, multi-station fixtures to enable the loading of multiple part batches, the solution features a dedicated user interface for ease of use, while a tailored reporting output aids part sentencing and quality control.

Explaining the reasons behind the recently installed Mitutoyo inspection system, Tecomet Sheffield product engineer Nigel Smith says: “Having won a long-term contract to produce femoral knee joints, we took the opportunity to carefully consider all of our related production and inspection options, and develop a range of effective new methodologies that would further increase our efficiency levels.

“As we regard inspection as an integral and vital part of our femoral knee joint production processes, we investigated ways of gaining additional efficiencies in this important area, while also seeking to improve our precision standards,” he continues. “The answer to our search was found in a custom-designed, highly-efficient inspection system from MGT.”

The MiStar 555 boasts a maximum permissible length measurement error specification of (2.2 + 3.0L/1000) μm and an XYZ measuring range of 570 x 500 x 500 mm. Mitutoyo’s CMM benefits from the company’s recently developed smart factory functionality that allows real-time monitoring of machine performance data, as well as measurement data.

Faster inspection of delicate parts

A new high-speed, non-contact sensor for use with CMMs from Hexagon’s Manufacturing Intelligence division addresses growing demand from the consumer electronics and medical industries to rapidly inspect delicate parts with a range of surface finishes, including those produced via additive manufacturing, without applying damaging pressure.

Manufacturers of components with vulnerable surface finishes struggle to achieve optimal efficiency because traditional tactile inspection can be time consuming, and parts often end up incurring damage during measurement. In cases requiring 100% component inspection, the deformation of delicate surfaces impairs productivity and, ultimately, the bottom line.

The new HP-OW chromatic white light sensor provides increased measurement speed and flexibility for OEMs, says Hexagon, and offers contract manufacturers the opportunity to employ new technologies and materials in production.

The sensor’s ability to measure components with transparent, polished, rough and matt finishes makes it easy to quickly and accurately measure parts made with delicate materials, including components such as LED vehicle lights and solar panels. Non-contact capabilities also offer high throughput inspection of medical devices, such as surgical implants, where the high-accuracy inspection of every part is essential.

Additive manufacturing processes pose unique challenges because parts often require measurement throughout production to ensure quality, but the cycle time needed to perform the precision inspection of rough unfinished parts can be prohibitive. As a new option in a line of specialised sensors extending the range of measurement technologies for use with a single CMM, the chromatic white-light scanning sensor offers an efficient way of scanning parts with high accuracy throughout production.

The new chromatc white light sensor is compatible with Hexagon’s Global S and Optiv M CMM lines.

LK releases CAMIO 2021 software

LK Metrology has released the latest version of its measurement, programming, analysis and reporting CMM software. Now called CAMIO 2021, numerous improvements help to increase inspection productivity, enhance the quality of data collected and gain better insight into the measurement of components.
For instance, CAMIO 2021 Geometry Validation reduces the time taken when preparing new inspection programs by automatically detecting which surfaces of the CAD model should be used to measure the feature. It ensures that all measurements are taken on suitable surfaces automatically, at the same time providing the programmer with the option to modify default settings and selections.

During programming of the feature, the CAD simulation highlights the geometry used for the validation and previews the measurement sequence. This preview combines with the teach path view to provide full visual and numerical evaluation of the programming sequence prior to executing the touch points or scanning sequence, enabling the programmer to get the inspection sequence right first time when programming online or offline.
Other improvements have been made to the programming workflow by extending the picking function to touch points and scan paths on a CAD model, and to indicate the selection of existing measured features.

New for CAMIO 2021, probe self-centring allows the centre point of a V-groove to be automatically located and measured using a scanning probe. This capability replicates hard gauging and measurement with gauge balls, typically used for gear tooth inspection and measuring countersink depth. Probe self-centring responds to the continuous deflections of an analogue probe in real time to locate the mid-point between two surfaces.
