01
A problem to clarify
We check part dimensions, geometry and tolerances against the technical drawing or CAD model.
DIMENSIONAL METROLOGY
CMM measurement and dimensional inspection services
Traceable CMM inspection to validate tolerances, compare against CAD and turn complex measurements into clear quality decisions.

REAL CMM MEASUREMENT EXAMPLES
See what we measure — and the information we deliver
Every component raises a different metrology question. We combine touch probing, continuous scanning, laser and vision with GD&T analysis and CAD comparison to turn geometry into quality decisions.
01Blade and aerodynamic profiles
Continuous scanning to analyse leading edge, trailing edge, curvature and the complete profile.
02Crankshafts and shafts
Control of diameters, positions, coaxiality, runout and relationships between multiple features.
03Engine blocks and automotive components
Measurement of planes, cylinders, bores, positions and functional datums in a single setup.
04Valves, seats and cylinder heads
Form scanning to verify roundness, taper, position and functional contact.
05Gaskets and flexible profiles
Controlled acquisition of contours, thicknesses, channels and deformation in delicate parts.
06Blisks and aerospace components
Inspection of complex geometry, profiles, twist and transitions with high point density.
07Combustors and formed sheet metal
Contact, vision and scanning combined for bores, surfaces and hard-to-reach features.
08Laser scanning on the CMM
Fast, non-contact point clouds for fragile surfaces, finishes and free-form geometry.
09Point cloud and CAD comparison
3D visualisation and deviation maps to quickly locate excess or missing material.
10Structured programming and inspection
CAMIO routines organised by features, tolerances and sequences to ensure repeatability.
11Cylinders, bores and internal geometry
Form, diameter, position and alignment analysis using multiple scanning sections.
12Measurement strategies and paths
Optimised paths to cover the right surface, reduce time and produce comparable data.
Representative CMM applications. Strategy, resolution and achievable uncertainty depend on the part, material, fixturing, tolerances, environment and inspection objective.
THE VALUE OF A PARTNER
A technical answer, not just a result
NM3D combines technology, software and application experience to turn data into a practical decision.
✓ Right method
✓ Clear result
✓ Specialists
✓ Continuity
HOW WE WORK
A simple process, from question to decision
Technical scoping
We collect CAD, drawings, tolerances, alignment references, part quantity and timing.
Work plan
We define fixturing, alignment, features to measure and the dimensional report format.
Execution and analysis
We perform CMM measurement and analyse deviations against the agreed tolerances and criteria.
Result and next steps
We deliver dimensional results and explain deviations to support decisions about the part or process.
Do you have a challenge that needs a technical answer?
We support projects in Portugal and Spain. Send the objective, photographs or CAD, dimensions and deadline.
Frequently asked questions
Que informação é necessária para pedir uma medição CMM?
Envie desenho ou CAD, tolerâncias, quantidade de peças, material, prazo e formato de relatório pretendido.
A NM3D realiza medições nas instalações do cliente?
Sim, quando a dimensão, logística ou processo justificam medição no local. A abordagem é validada antes do serviço.
O relatório inclui GD&T e comparação com CAD?
Pode incluir resultados dimensionais, GD&T, mapas de desvio e comparação CAD, de acordo com o plano de inspeção.
Quando compensa subcontratar a medição CMM?
É útil para picos de trabalho, validação inicial, peças especiais ou quando ainda não existe capacidade interna adequada.
