  1. 1. REVERSE ENGINEERING DEMONSTRATIONS Senior Engineer - Design & Development GTDMC, Pakistan Syed Zillay Ali
  2. 2. WHAT IS REVERSE ENGINEERING? A process of discovering the technological principles of a human made device, object or system through analysis of its structure, function and operation
  3. 3. Reverse Engineering Tools 3D-Printer Laser sintering machine CMM 3D-Scanner
  4. 4. 3D LASER SCANNER USED EXTENSIVELY FOR REVERSE ENGINEERING
  5. 5. PROJECT-1 DIGITAL PARTS CATALOGUE  Engine Housing for an obsolete model of agricultural Tractor vehicle required a complete set of Digital Drawings in order to ensure future repair and maintenance / spares manufacturability.  The Project was taken as a challenge  Starting by making 3D Point Clouds Data, the final CAD models for a total of 11 components were accomplished in less than 60 days Original part Point Cloud Data Model
  6. 6. PROJECT-2 CAD-TO-PART INSPECTION CAD VS. Cloud Inspection using PowerInspect® & Geomagic Qualify® Point Cloud Original CAD Model Original part • A Motorcycle Chassis Trim was manufactured using newly developed Toolings and it was required to be inspected if it conformed to the original Design. • So using 3D Laser Scanning, points-cloud data was generated and compared against the original 3D CAD model. • Variations were then traced and controlled.
  7. 7. • A sculpture of Mr. Muhammad Ali Jinnah (Quaid-e-Azam) – the Founder of Pakistan, was 3D Laser Scanned. The points-cloud data was used to produce a 3D CAD Model. • The 3D CAD Model was then used to produce 10 replicas of the same sculpture through SLS Rapid Prototyping methods.
