From a worn or obsolete component to the engineering information needed to make it again. Explore real parts, their reconstructed 3D models and a manufactured replacement.
An existing compressor crankshaft provides the physical reference for reconstructing the shaft, crank geometry and journal interfaces in CAD.

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.
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.
