CASE 01 / REVERSE ENGINEERING

Compressor crankshaft

Recreating complex geometry at an 8-metre scale

Overall length
8 m
Main & crankpin journals
Ø 400 mm

An existing compressor crankshaft provides the physical reference for reconstructing the shaft, crank geometry and journal interfaces in CAD.

CASE 02 / REVERSE ENGINEERING

Compressor cylinder

From the installed component to a digital model

Material
Cast iron
Weight
800 kg
Overall length
880 mm
Outside diameter
535 mm

The cast-iron cylinder is documented as a 3D model, capturing its overall form, flanges and connection geometry.

AFTER RESTORATION

Precision is checked
on the component

Watch a close-up dial-indicator check on a machined surface after restoration. Measurement connects the engineering model with the physical result.

Inspection methods and acceptance criteria are defined for each component and its operating requirements.

FROM SAMPLE TO MANUFACTURING INFORMATION

A clear route to your replacement part

01 / Inspect & measure

Review the physical sample, damage, available drawings and critical interfaces. Capture dimensions and geometry through measurement and 3D scanning.

02 / Reconstruct & document

Build the CAD model and develop manufacturing drawings, with materials, tolerances and interfaces defined for the agreed scope.

03 / Manufacture & verify

Coordinate manufacture against approved documentation and verify the component against the agreed inspection requirements.

PROJECT QUESTIONS

From an existing part to manufacturing information

Explore compressor and turbine repair ↗

Can a component be reproduced without original drawings?

An existing part can provide the starting point for dimensional measurement and CAD reconstruction. Wear or damage must be assessed so the engineering model does not simply reproduce defects in the sample.

What is the difference between a 3D scan and a CAD model?

A scan captures measured surface geometry. CAD reconstruction interprets that information into a component model. Manufacturing drawings then define the agreed dimensions, interfaces, materials and tolerances needed for production.

Which components are shown in these examples?

The case studies above show compressor crankshafts, cylinders and a crosshead. Send photographs, available dimensions and operating information to discuss an obsolete or damaged component and the documentation required.
