Manufacturing Features in Cutting Shapes and Punching Holes in Sheet Metal

By examining sheet metal parts it is rather evident that each sheet metal shape has its own manufacturing procedure. There are several manufacturing devices behind each procedure. This means that each shape can be divided into manufacturing features, which consist of shapes of sheet metal and their manufacturing methods. When creating rules and structures for manufacturing features, it is possi...

Algorithms for sheet metal nesting

This paper discusses the problem of minimizing the cost of sheet metal punching when nesting (batching) orders. Although the problem is NP-complete, the solution to a linear programming relaxation yields an efficient heuristic. This paper analyzes the heuristic’s worst-case performance and discusses experimental results that demonstrate its ability to find good solutions across a range of cost ...

Mutual Inductance Problem for a System Consisting of a Current Sheet and a Thin Metal Plate

Rapid inspection of aircraft structures for flaws is of vital importance to the commercial and defense aircraft industry. In particular, inspecting thin aluminum structures for flaws is the focus of a large scale R&D effort in the nondestructive evaluation (NDE) community. Traditional eddy current methods used today are effective, but require long inspection times. New electromagnetic technique...

Three-dimensional localization of thin-walled sheet metal parts for robotic assembly

This article presents a technical demonstration of a system for determining the threedimensional spatial location of complexly shaped, thin-walled sheet metal parts grasped by robots during assembly. For successful part assembly, the precise location of grasped parts (essential for successful mating of parts) must be achieved. A localization system is implemented to determine the accurate posit...

Accuracy of a domain decomposition method for the recovering ofdiscontinuous heat sources in metal sheet

This paper describes a method for the retrieval of discontinuous heat sources involved in a metal cutting process. Two smoothing techniques were used in the present study in order to smooth noisy sensor data recorded by temperature sensors. The two smoothing techniques are a least squares polynomial t and a La-grangian smoothing. These data are then used to recover the heat source. It is found ...
