摘要:

A new scaling linkage is presented which allows arbitrary magnification or reduction of curves and drawings in theydirection while leaving dimensions in thexdirection unchanged. The anisotropic pantograph represents a significant simplification over previously reported devices capable of this operation. MagnificationsMyin the range 1.05–80.0 and reductionsRyin the range 0.0125–0.95 are obtained using a single operation, and the tracking accuracy is <±150 &mgr;m. With the aid of a circle template or flat compass, the device may be used to draw arbitrary ellipses. A method for effecting arbitrary shears, and various methods for arbitrary scaling in two orthogonal directions are outlined.
