Pantograph Engraving Machine - A Review
This project ‘Pantograph Engraving Machine (PEM)’ is designed and is used mainly to cut wood, plastics, mild
steel plates in to any shapes with desired accuracy and correctness. The Pantograph machine consists of the traditional
cutting equipment along with a pantograph which is a mechanical linkage connected in a manner based on parallel orgasm
and which is further used for copying and scaling line drawings and complex images. The working principle of pantograph
engraving machine is based on four bar mechanism in which one link is fixed and other links are pivoted. These other links
move according to the movement of the tracing link. This is a low cost and high valuable apparatus. In this project, a model
of the Pantograph engraving machine will be designed using CAD packages like AutoCAD, pro- e etc. taking into
consideration of the commercially available components. Care has been taken in the fabrication of components. The lack of
accuracy and precision in fabricated components would lead to a diminished performance of the machine resulting into a
poor surface finish.
