Abstract

Nowadays the design constructional process is almost exclusively aided with CAD/CAE systems. A design engineer is subjected to a series of design iterations prior to the final required design in any CAD package. The major concern of a design engineer is to develop the required product through design iterations at the least time possible, which is possible only through automating the tasks. This paper is to illustrate a method to automate the repetitive tasks included in the designing process. Here, we take the example of a popular mechanical part, i.e., cam to illustrate automation in the CAD package CATIA V5. The aim of this work is to automate the 3D modelling of different types of cam profiles within the CATIA V5 environment by using Visual Basic programming (VBA) language and integrating it with user-form from the conventional designing procedures. The developed user form using VB programming will enable any engineer to design the part even without any prior knowledge or skills in CAD/CATIA V5. It is observed that 90% time will be reduced by using this automated designing and also chance of errors also reduces.

After designing a part, the engineer is then concerned about how long the designed part will last, i.e. life. So, determining the life of the part is also an important task. The second part of this paper is the life assessment of the designed cam due to the dynamic loads acting on it. Fatigue life of the cam is estimated by simulating the cam-follower motion in ANSYS 18.
