Parallel Radial Line Development In Sheet Metal

Radial line parallel line development sheet metal mathematics volume 2 of sheet metal layout simplified hugh b.

Parallel radial line development in sheet metal. But in parallel line development the reference lines are parallel like a picket fence. A flat steel square is used for making perpendicular or parallel lines. 8 30 transition piece a transition piece is one that connects two differently shaped differently sized or skewed position openings. Sheet metal layout simplified.

Feb 12 2008. In radial line development the reference lines radiate from the apex of a cone like the spokes of a wheel. In the method of layout known as parallel line development the flat steel square is used to create lines that are parallel to each other as well as perpendicular to the base line. But in parallel line development the reference lines are parallel like a picket fence.

The centre line of the hole and the corresponding heights have been projected from the front elevation. Radial line development. 04103 08 introduction to sheet metal layout and processes 7 5 hours introduces parallel line development radial line development and triangulation. Evenly spaced reference lines are necessary in both of these methods.

The radial line method is similar in some respects to the parallel line method. In most cases transition pieces are. Divides the surface into a series of parallel lines to determine the shape of a pattern. In general it is used to develop square rectangular and cylindrical.

Parallel line development uses parallel lines to construct the. Parallel line development. Lithographed by edwards bros 1963. 1 1 parallel line development the parallel line method of pattern development is based on a system of lines drawn parallel to one another on the surface of a sheet metal article and is used to develop items such as elbows segmental bends tee pieces or valve boxes for example.

Describes the hand and power tools used in the sheet metal trade including layout tools and cutting bending and forming machines. An example of radial line development is given in fig. The university of michigan. In radial line development the reference lines radiate from the apex of a cone like the spokes of a wheel.

The method of drawing a pattern for the branch is identical to that shown for the two piece elbow in fig. Includes safety and maintenance guidelines. The radial line method is similar in some respects to the parallel line method. This procedure is shown in figure 13 2.

Simply clamp the straightedge firmly to the base line. Evenly spaced reference lines are necessary in both of these methods. Radial line development uses lines radiating from a central point.
