Endcut Standards in AVEVA Marine, Principles

AVEVA Marine contains a vast in-built endcut standard that is delivered to all customers. The standard is divided into a number of predefined endcut types. An endcut type corresponds to a certain geometrical pattern. Its actual shape may be controlled by a number of parameters some of which are set up in a standard table. Others must be given by the designer or are calculated automatically by the system, for example, depending on the connection in which the profile end is involved. A typical example of a simple endcut for a flat bar is illustrated below (standard endcut type 11).

Figure 6:1. Standard Endcut 11.

The shape of this and all other endcuts is controlled by three different types of data items.

1. The endcut type (in the example above the endcut type is 11).

2. A number of implicitly defined parameters with standard values. The parameters that may have standard values are individual to a certain endcut type. These parameters have a restricted number of values and each combination of them is identified by an endcut code. The standardized parameters are either radii or fixed angles of the endcut and they cannot be given explicitly by the designer but are selected via the endcut code. In the figure above R1 and R2 are such parameters.

3. A number of additional parameters which may take any value and which are explicitly given by the designer or automatically calculated by the system.

   In the example above V is such a parameter. These parameters are given as explicit complements to the endcut code.
