The wear of parts and components of machines during their work ultimately leads to disable their parts of further exploitation. The easiest way to repair this situation is the replacement of the defective part with a new one. The problem arises when the needed components are no longer commercially available and there is no access to their technical documentation. This kind of problem is often encountered in the industry. This mainly applies to machines and tools, which are manufactured individually, such as special machines, molds or stampings. Reverse Engineering is the solution for this kind of situations.
It is a process in which on the basis of the real object there is created the 3D CAD model. This method turns out to be very simple and inexpensive. It allows to make precise scan of the damaged object, recreating the technical documentation and ultimately produce a replacement for the part. The whole can be done by successive measuring of the coordinates of characteristic points which are stored in computer memory.
Techniques associated with reverse engineering are used wherever there is a need to create a digital model or documentation for objects that do not have it. This applies not only for worn elements. Increasingly, these techniques are used in industrial design, when the first physical prototype is created – often using hand tools. Then the digital model and technical documentation are created, to enable the implementation of production.
Centre for Innovative Technology has two 3D scanners:
- green light scanner – with scaning accuracy up to 0.01 mm,
- white light scanner – for medical purposes, exposure time about 1.5 seconds and a capability of color reproduction of the scanned object.
