I need to create the 3D model (Reverse Engineering) from actual parts (pinion and gear Spiral Bevel set). How the tooth dimensions (such as pitch diameter, root diameter, form diameter, clearance, helix angle, etc, etc) can be extracted from the actual parts in order to create the 3D model of this set?. Does anyone know the typical procedure to follow?. I am thinking in "gear gauges" or special template for the tooth form and for the spiral angles (something like the thread gauges that can be superposed on the actual thread, so the thread can be identified). The basic "external" dimensions such as the major and minor diameter of the cone, the taper of the cone, tooth face width, number of teeth can be roughly be figured out, but what about the information to 3D model the tooth geometry?. Thank you in advance!.

Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
