Mechanical Engineering Case Study

Reverse Engineering Crankshaft Design for Automotive Parts Manufacturers & Suppliers, USA

The Client
Automotive Parts Manufacturer, USA

The Objective

To reverse engineer crankshaft and identify accurate dimensions needed for manufacturing.

The Solution

The point cloud data captured was converted into polylines & this data was then imported to Pro/E. With the data, a Pro/E model was created which was used to carry out further analysis of the design & create production ready drawings, once the necessary modifications were carried out.

Reverse engineering benefits in obtaining useful design information about components becoming obsolete and have few information available to re-manufacture. It is a vital tool to study the component design in layers of information and identify the effort required to recreate the same.

A leading auto parts manufacturer in US was in need of reverse engineering the crankshaft, which was designed to be utilized in vintage cars. Due to unavailability of design information, manufacturing the crankshaft required suitable production ready drawings.


Engineering Solution

The problem was dealt with Hi-Tech’s three step process of Reverse Engineering: Data digitization-Data Integration–3D CAD Modeling. To accurately reproduce the design of the crankshaft, all the dimensions were first digitized using manual laser scanning & CMM measurement techniques.
