Abstract
Abstract A graphical method for determining corrections required to align one machine element with another employing a plotting boardoverlay combination comprising a grid, said grid comprising scale means whereon is represented machine element spatial orientation and dimensions, and a transparent or semi-transparent form for overlay onto said plotting board whereon is plotted said one machine element spatial orientation and dimensions. The method comprises superposing said form onto said plotting board, plotting machine spatial orientation and dimensions of said one machine element onto said overlay form, repositioning said overlay form to correspond with existing machinery orientation, and reading magnitude and direction of said required misalignment corrections directly from said plotting board grid.
