This paper presents design and construction of an automatic moldboard profilograph by substituting an optical sensor and a control system together with its evaluation. The modified profilograph is an electro mechanical apparatus in which a micro switch and a DC motor was replaced with an optical sensor and a control system for revolution of a DC motor. Thereby, the considered surface is measured using a non – contact sensor. This apparatus has the capability of drawing the profilograms of a 3-D object as a 2-D drawing in the same contour lines. The profilograms drawn by this apparatus can be useful in moldboard design and its surface modeling. In the end, drawn profilograms before and after modification were compared. Then, to verifying apparatus performance, the horizontal and vertical profilograms of a cylindroidal moldboard was drawn.
