Parallel Radial Line Development In Sheet Metal
A flat steel square is used for making perpendicular or parallel lines.
Parallel radial line development in sheet metal. An example of radial line development is given in fig. Radial line parallel line development sheet metal mathematics volume 2 of sheet metal layout simplified hugh b. Radial line development uses lines radiating from a central point. Radial line parallel line development sheet metal mathematics sheet metal layout simplified volume 2 hardcover january 1 1981.
The method of drawing a pattern for the branch is identical to that shown for the two piece elbow in fig. 04103 08 introduction to sheet metal layout and processes 7 5 hours introduces parallel line development radial line development and triangulation. Includes safety and maintenance guidelines. The radial line method is similar in some respects to the parallel line method.
Lithographed by edwards bros 1963. Feb 12 2008. The centre line of the hole and the corresponding heights have been projected from the front elevation. Transition pieces are the sheet metal objects used for connecting.
Evenly spaced reference lines are necessary in both of these methods. 8 30 transition piece a transition piece is one that connects two differently shaped differently sized or skewed position openings. Divides the surface into a series of parallel lines to determine the shape of a pattern. 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.
In most cases transition pieces are. But in parallel line development the reference lines are parallel like a picket fence. The radial line method is similar in some respects to the parallel line method. Describes the hand and power tools used in the sheet metal trade including layout tools and cutting bending and forming machines.
In radial line development the reference lines radiate from the apex of a cone like the spokes of a wheel. Sheet metal layout simplified. Simply clamp the straightedge firmly to the base line. 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.
The university of michigan. Evenly spaced reference lines are necessary in both of these methods. Parallel line development. Parallel line development uses parallel lines to construct the.
In radial line development the reference lines radiate from the apex of a cone like the spokes of a wheel. But in parallel line development the reference lines are parallel like a picket fence. Sheet metal construction is the most common.
