Automated dimensional measurement systems online
July 23, 2021

Two new models suitable for automated dimensional measurement tasks online have been added to Nikon Metrology's latest Nexiv S range of CNC video measurement systems.

The Nexiv CNC video measurement system can automatically measure component dimensions using Nikon's world-renowned optical and image processing technologies. By analyzing the image taken from a component, detecting the edges of the characteristics at high speed, both accurately and repeatedly, it is then possible to quickly measure components with simple and complex characteristics.

With the growing demand for smaller components with higher performance, as well as the increase in the number of electronic components in automobiles, video measurement systems need to measure more components at a higher speed in automated production lines.

The Nexiv VMZ-S series enables this by maintaining and improving the performance of the previous model of the Nexiv VMZ-R series. Indeed, in November 2020, Nikon launched the first model in the range of new VMZ-S systems, the VMZ-S3020, which is part of the fourth generation of the Nexiv series. The VMZ-S4540 and VMZ-S6555 now complete this range: they are solutions for medium or large components or for loading several components.

All models of the Nexiv VMZ-S series are now available, offering a choice of machines depending on the applications and the customer's installation environment. In addition, thanks to the Remote Control SDK software (optional), several Nexiv systems can be fully integrated into the production line, with remote access and control.

Improved throughput

According to Nikon, Nexiv systems achieve the highest level of measurement accuracy thanks to an exceptional platform including high-precision linear encoders. The Nexiv VMZ-S series is capable of taking and processing images at higher speeds than its predecessor, the Nexiv VMZ-R series, reducing component measurement cycles with accuracy or reproducibility.

High-quality images and accurate measurement data

Nikon has designed and optimized an optical system to provide high-quality images and accurate measurement data within the field of view. With a removable LED lighting ring and 8-segment LED lighting, it is possible to observe and measure the edges of complex shapes. In addition, a scanner at the scanning speed of 1000 points/sec can acquire the cross-sectional profile of a surface and evaluate the relative heights. This meets the needs of surface quality and feature measurement for a wide variety of samples.

Advanced ergonomics

AutoMeasure's measurement software environment enables high accuracy, high speed, with simple measurement functions. A large library of valuable tools is available in a user-friendly interface. For simple components, a helper function is used to automate part of the measurement programming process.

The joystick unit used to move the tray and the measuring head have also been redesigned to offer even greater ergonomics to the operator.

Control multiple Nexiv systems remotely

Up to 10 Nexiv systems can be controlled remotely with the optional Remote Control SDK, which enables centralized management and distribution of measurement programs and results from a single location. By controlling Nexiv and measurement programs from a location away from the production line, such as a control room or office, the workforce can be streamlined and productivity improved.
