Size Compensation for Swaging

All parts are in the model described to their nominal sizes, also swaged parts. In applying the swages the extension of the plate is reduced, since part of the plate is "consumed" by the swages. Consequently, when extracting the parts from the model their size must be compensated for the amount of plate that goes into the swages.

The swage object contains information about the material addition caused by the swages. There are the following options.

Figure 2:1. Height and width of swage.

• The amount of material addition is specified for one swage.

• It should be set up individually for each type (and size (H) in case of multiple sizes) of swage.

• The addition can be defined as depending on the plate thickness.

• It is possible to define the width (D in the figure above) of a zone around the description line of the swage that should be subject to deformation. This zone will then be stretched accordingly when the plate parts are extracted.

The two lines restricting the zone of width D intersect the outer contour of the plate part. After stretching the two intersection points along one edge will be connected by a straight line. If the swage intersects the edge at an angle this will introduce small knuckles in the edge contour.
