Inspection fixture design
We design inspection fixtures and gauging devices tailored to your part, to check dimensional conformity quickly, repeatably and in a way that is easy to use in production. To learn more, see the Wikipedia article on quality control.

An inspection fixture positions and holds a part in a defined position, to check whether it meets the dimensional specifications. It allows quick, repeatable inspection, directly in production or in the quality lab.
At INOVAMIND we develop the fixture design: we study the part and the inspection requirements and define the most suitable positioning, clamping and measuring solution.

How we define positioning in inspection fixtures
The part must sit in a single, repeatable position. For this we use the references from the drawing (the datums): three support points define the main plane, two define the direction and one locks the rest. If the drawing does not define them, we propose the most logical ones and validate them with you.
What type of inspection fixtures you need
| Type | What it is for |
|---|---|
| Inspection fixture | Checks the position and shape of the part and shows deviations |
| Holding fixture for measurement | Holds the part during CMM or 3D scanner measurement |
| Go / no-go gauge | Very fast check of a specific feature |
| Holder for dial gauges | Measures a specific dimension directly on the part |
Designed for the people who use it
A good fixture is simple to use: the operator understands where to place the part, the clamps always tighten the same way, measurement access is easy and the reading is clear. We also think about maintenance: wear of the supports, replacement of parts and reliability over time.
How we work on inspection fixtures
Analysis
We study the part, the drawing and the inspection requirements. If there is no CAD model, we can 3D scan the part.
Design
We design the fixture in 3D: positioning, clamping and measurement access.
Review
We validate the design with you before moving on to manufacturing.
Delivery
We deliver the fixture design, ready to be manufactured.
Inspection fixtures
What is an inspection fixture?
It is a device that positions and holds a part in a defined position to check whether it meets the dimensional specifications. It allows quick, repeatable inspection, directly in production or in the quality lab.
When is a fixture better than a measuring machine?
A fixture is suited to frequent, quick checks carried out by operators on the line. A measuring machine or a 3D scanner gives a more detailed analysis. They are often used together: the fixture for daily inspection and detailed measurement to validate and analyse deviations.
Do I need to have the CAD model of the part?
It helps, but it is not essential. If there is no CAD model, we can 3D scan the part to obtain the data the design needs.
Does INOVAMIND manufacture the fixtures?
We develop the fixture design. Manufacturing is not included; we discuss the best solution with you for each case.
How do I request a proposal?
Send us the drawing or photographs of the part and the inspection requirements, through the contact form, WhatsApp or by phone. We analyse the request and reply with a proposal.
What is the difference between a fixture and a go / no-go gauge?
The gauge checks a single feature (for example, a hole). The fixture holds the whole part and lets you check several features at the same time.
What information do I need to provide?
The drawing or CAD model of the part, the tolerances and features to inspect, the quantity to produce and the place of use (production or lab).
Can you design from the part, without a drawing?
Yes, we scan the part and create the base model for the design.
