Result of Manufacturing Curved Plates

The resulting information consists of:

• Jig object stored in the data bank.

• Lists.

• Drawings.

Further details are given below.

The positions of the jig rows are calculated as follows:

1. Intersect the assembly plane with a frame or waterline plane (depending on the selected direction seam).

2. Calculate a plane parallel to the intersection line defined by the JIG_PLANE_POSITION statement and perpendicular to the assembly plane. The plane should touch the utmost point of the given seam.

3. The intersection line between this plane and the assembly plane is defined as the direction line (=y-axis of the jig coordinate system).

4. Calculate a new plane perpendicular both to the assembly plane and the direction line (y-axis).

5. Let this plane touch the curved panel so that its intersection with the assembly plane, defined as the sight line, forms a coordinate system together with the direction line. Make the sight line the x-axis. Make the direction line the y-axis, and place the curved panel in the first quadrant.

The jig rows are parallel to the direction line (y-axis).

The jig row closest to the direction line (= the y-axis) is jig row A, the next one B, and so on.

The first jig row will be positioned at the distance given by the IP DIST_TO_FIRST_JIG_ROW from the y-axis. The first jig pillar in a jig row will be positioned according to the ip DIST_FIRST_PILLAR. The jig pillars of a jig row will have the standard partition as given by the IP PILLARDISTANCE. The partition between the jig rows is given by the ip DIST_BETWEEN_JIG_ROWS. The minimum jig pillar height is given by the IP MINPILLARHEIGHT.

The jig pillars in a jig row are numbered 1, 2, 3, ... , according to the order in which they appear in from the sight line (= the x-axis). The name of a pillar is a combination of the jig row name and the order of the pillar within the row. For example, the third pillar in row B gets the name B3.
