Metrology Fixture Design
We believe that having a creative and innovative approach to clients’ measurement challenges is crucial, whilst maintaining a robust and simple design. That is why over 150 client companies have partnered with Verus Metrology to design and develop bespoke metrology fixtures to date.
Our reputation for design optimisation will always have the end result as the key focus. We work closely with our clients from product concept to completion, developing and delivering world class metrology fixtures, in the most effective and efficient manner. The vast experience available within the design team continues to save our clients time and resources. We strive to offer the best advice to our clients on their components, considering processes and tolerances, while predicting any future potential metrology challenges.
Verus’ design team specialise in bespoke Metrology Inspection Fixtures for CMM and Vision systems and Hybrid Inspection Fixtures for use on Vision System CMMs with touch trigger capability. Our metrology fixtures can range from single station to large repeat multi-station solutions and can incorporate manual or auto-rotational features.
Through our metrology workshops at the beginning of a new project, the design team will work with the client and our metrology engineers, to develop initial concepts and single station prototypes. Once our digital concept is proven out and client approval is obtained, it is then ready for manufacture. This process ensures a fast design and development cycle and an optimised final Inspection fixture solution.
Designed by metrology engineers for metrology engineers, our bespoke fixtures help reduce operator interaction, minimising the risk of interrupting measurement results. Through innovative advancements, our metrology fixtures allow for the maximum number of measurements to be taken with the minimum number of setups. In most cases we can develop a single inspection fixture that will allow all dimensions to be taken on any component.
We develop the initial concept design into final high-cavitation multi-station fixtures. Our goal is to optimise client’s production processes through the innovative design and use of our bespoke metrology fixture solutions.

Metrology Fixture Manufacture
As toolmakers, Verus Metrology prides itself on the quality, precision, functionality and finish of the Metrology Inspection Fixtures we design and manufacture. From large, complex components to smaller, more intricate parts, our bespoke fixtures improve productivity and increase throughput, saving our clients time and resources.
Since our establishment, we have achieved immense expertise and experience in the manufacturing of our bespoke Metrology Inspection Fixtures. This wide spectrum of proficiency includes the manufacturing of fixtures for single component measurements right through to highly sophisticated, large multi-station metrology fixture solutions. Verus has the capacity and capabilities to provide superior, extremely complex, single-station and multi-station inspection fixtures fit for components of any shape or size.
To ensure a fast production turnaround, Verus provides a full in-house manufacturing facility offering highly skilled CNC Machinists, Engineers and Toolmakers. Our world-leading CNC machining teams produce a reliable and repeatable process, resulting in the highest quality of completed metrology fixtures. We develop close working relationships with our clients based on an innovative and mutually respected process of continual improvement.
The manufacture and assembly of our first-class metrology fixtures at each of our facilities enables Verus to service clients worldwide. Our manufacturing facilities, machines and services are tailored to respond to each of our global client’s individual metrology requirements.
Verus’ Fixture Manufacture Process
Adding extra value to client’s measurement activities, our metrology fixtures are second to none in the market. Verus’ in-house manufacturing process results in the highest quality of manufactured precision measuring equipment and metrology fixture solutions. Once our expert manufactures receive the required book of drawings to match the CAD model, our fixture manufacturing process involves:
- Order Any Required Material
- Mill + Turn the parts from Aluminium, Acetal, Peek, Stainless Steel and Tool Steel
- Fixture Functioning Approval
- Fixture Anodising and Hardening
- Laser Etched of Fixture (If Required)
- Final Assembly
Metrology Fixture Qualification
Verus Metrology strongly believes in delivering a Metrology Inspection Fixture that will perform and function to the highest of standards. To support this, we perform gauge R+R on all the Metrology Inspection Fixtures we provide.
Verus' Qualification Process
Gauge R&R is a statistical tool that measures the amount of variation in the measurement system arising from the measurement device and the people taking the measurement. A gauge R&R study allows us to investigate:
- Repeatability—How much variability in the measurement system is caused by the measurement device.
- Reproducibility—How much variability in the measurement system is caused by differences between operators.
When measuring the product of any process, there are two sources of variation: the variation of the process itself and the variation of the measurement system. The purpose of conducting the GR&R is to be able to distinguish the former from the latter, and to reduce the measurement system variation if it is excessive.
The Gauge R&R studies carried out by Verus on all our metrology fixtures aim for a GR&R variation of less than 10% of the tolerance range.
Once the gauge R+R has been completed, the results are loaded into our statistical software package. Only once it has passed our strict criteria is the metrology fixture released for delivery.
CMM/Vision System Programming
Along with the gauge R+R report, our bespoke fixtures can be shipped with a programme ready to be loaded to the clients CMM or Vision system metrology machine. Our expert Metrology Engineers can create, verify and install bespoke metrology fixture programmes on multiple CMM and Vision Systems.
They variety of machines types we work with, along with our capacity enables Verus to offer individually tailored solutions designed to meet each client requirement.
If requested by the client, onsite support can be provided by one of our expert engineers for installation and qualification.
Tests and validations of the programme can be completed and sent to the client before shipping to ensure no delay in the inspection fixture deployment.
We also recommend Metrology Inspection Fixtures are returned for requalification on an annual basis depending on levels of use. The metrology fixtures will be inspected checked for wear and tear and a new gauge R+R carried out to re-qualify.
