TAP Statement

- 3 minute read
Panels are split into parts by seams. In the assembly process the parts are welded together along the seams. To ensure a good welding result the parts are sometimes extended with extra pieces of material, here called ‘taps’. Taps may be added when a seam passes across the following types of components:
-
Plate edges/ panel boundaries
-
Holes
-
Notches
-
Cutouts
Additionally, taps may be set at corners of panels when butt-welded to parts form another panel.
In the panel taps are represented only as attribute information. They are converted into real geometry in the automatic parts generation (ppanparts). In symbolic views they are represented by a special symbol.

Description
|
TYPE |
Is the standard type of a certain tap defined in __SBH_TAP_CTRL_ <type_code>::= <integer> |
|
COR |
Defines the corner of the plane panel where to place the tap. <corner>::= <integer> The keyword may only be used in combination with the keyword LIM. |
|
SEA |
Defines the intersecting seam <seam_no>::=<integer> |
|
LIM |
Together with COR: Defines the limit where to place the tap. Together with SEA; Defines the limit to be intersected by the seam to locate the tap. <limit>::= <integer> |
|
CNO |
Defines the hole to intersect with SEA. If the seam intersects the hole twice, there will be one tap at each intersection point. <hole_no>::=<integer> |
|
NOT |
Defines the notch to intersect with SEA. |
|
CUT |
Defines the cutout to intersect with SEA. <panel> is an intersecting panel with a profile for which a cutout is defined. If left out, a shell profile is assumed. <prof_no> is the profile number for which a cutout is defined. |
|
NO |
Normally, taps will be numbered automatically and get the first free tap number (1, 2, ... ). However, the tap numbers can be controlled via input. Note: Two taps may never be given the same number. <no>::=<integer> |
|
COLOUR |
Color of the tap defined in the statement. |
|
COMMENT |
An arbitrary comment string |
|
<symmetry> |
Taps in symmetrical panels ("SBPS-panels") are normally supposed to be valid portside and starboard. This clause may be used to indicate that a certain tap is relevant portside only or starboard only. It is relevant only for symmetrical panels. <symmetry>::= P | S P means port side specific S means starboard specific. |
Examples:
|
1 |
Tap at intersection between seam and limit |
|
TAP, TYP=2, SEA=1, LIM=2; TAP, TYP=2, SEA=1, LIM=4; |
|
|
2 |
Tap at intersection between seam and hole |
|
TAP, TYP=1, SEA=1, CNO=1; TAP, TYP=1, SEA=2, CNO=1; |
|
|
3 |
Tap at intersection between seam and notch |
|
TAP, TYP=2, SEA=1, NOT=1; |
|
|
4 |
Tap at intersection between seam and cutout |
|
TAP, TYP=1, SEA=1, CUT, 'AA123-345', LP13; |
|
|
5 |
Tap at corner of limit (in this example the plates parts are supposed to be butt-welded to parts from other panels along limits 2 and 4). |
|
TAP, TYP=2, COR=3, LIM=3; TAP, TYP=2, COR=4, LIM=3; |
