Development of a Drilling Machine for an Asymmetric Element with Multiple Holes

The aim of this paper is to develop a drilling machine for 5 holes simultaneously manufactured for an asymmetric element from automotive industry. The function analysis system technique (FAST) and SADT (Structured Analysis and Design Technique) is used to identify, describe and categorize the drilling machine functions in order to propose technical solution. The paper propose an original solution with flat extruded engine for the closest 2 holes to avoid the usage of multispindle head.
