Abstract

One of the major problem during sheet metal working is cutting of large and complex shapes on the sheet metal. This is due to errors and involvement of large process and equipment’s in drawing those shapes, like drawing a circle with big diameter is very difficult (Range of compass is 300mm diameter). Drawing a complex shape on sheet metal needs a scale, protector, compass, drafter etc., and for some shapes like parabola and ellipse, we do not have the equipment to draw. But a similar shape on in a smaller scale is easier to draw in software like AutoCAD and solid works and can easily take print out for the smaller scale. If the same drawing can be magnified, the difficulty in drawing the complex shapes on sheet metal can be minimized. Therefore, this project is aimed at developing a Pantograph mechanism, which can be used to magnify the smaller shapes on the sheet metals. And it replaces all the drawing tools on the work table. Another use of this mechanism is a single reference drawing is enough to draw a similar magnified drawing on many sheet metals.
