REVERSE ENGINEERING OF IC ENGINE CONNECTING ROD OF HERO- HONDA MOTORCYCLE ENGINE

The connecting rod is modeled from cloud points obtained by laser beam scanning. The points are joined by lines and then creating bounding areas and filling the volume.The laser beam scanning method for inspecting a reflective surface has been studied with analytical derivations and numerical modeling. Specular reflection off the surface was assumed and mathematical relations consistent with analytic geometry were used to trace the laser beam and predict its screen projection. It was found that deviation of the screen projection is proportional to the surface slope along the projection direction at the reflecting point and the distance from the point to the screen. The 3-D modeling was validated with 2-D analytical relationship as a special case and was tested with a profiled SMC (sheet molding compound) panel.
