Our objective is to make machinery for stamping details on water bottle cap. As company is small scale company it requires a machine with low cost, high accuracy, less floor area and less interaction of human being. We made a machine with same requirement using Geneva mechanism for indexing purpose which reduces human interaction. For stamping we use electromagnetic actuator which is actuated using ultrasonic sensors to read the location of cap under the plunger. Geneva table reduces the floor area and also makes the loading, unloading and indexing simple in one mechanism. Using sensors stamping becomes automatic and overall cost becomes very low as compared to the machineries used in industries like laser printing and all.

This paper describes a scheme which allows two separate finite element meshes to slide into and thus overlap each other. The Lagrange multipliers method is used to couple the two meshes together at their boundary. Overlapping elements are dealt with by adjusting the contributions of the elements of one of the two meshes to the system matrix according to the extent of overlap in such a way that at total overlap, those elements are effectively decoupled from the model. Applications include the modelling of electromagnetic plunger type devices.
