Automatic Broaching Tool Design by Technological and Geometrical Optimization

The paper presents an approach for automatic broaching tool design for a user-defined complex-shaped slot. A systematic method was developed to generate a cutting strategy for the broach. A set of technological constraints such as maximum allowed cutting force per tooth or maximum allowed rise per tooth are considered. Thereby, an optimization based on the cutting forces is carried out.Aim of the automatic, technological and geometrical based broaching tool design is to reduce the total length of the broaching tool. Hence, manufacturing cost of the tool itself is reduced as well as manufacturing time of each slot and thereby, production costs of the slots are optimized.
