Abstract

Indigenous product development using conventional means involves a relatively long lead
time and cost, especially for replacing worn out and broken parts. This paper presents
methodologies and technologies for computer-aided reverse engineering, illustrated by a reallife
case study of an aluminium alloy separator body of a hydraulic filter assembly for the special
army vehicle. It involved reconstruction of part geometry using 3-D scanning, material
identification using spectrometry, casting process optimisation using simulation software, and
fabrication of prototype and tooling using rapid prototyping systems. It was found that the
fabrication of wax patterns directly from reverse-engineered CAD data in a suitable rapid
prototyping system (such as thermojet), followed by conventional investment casting, gives a
reliable and economic route for rapid development of one-off intricate parts for the replacement
purpose.
