Abstract

Incremental forming is a sheet metal forming technique in which a uniform sheet is plastically deformed through the progressive action of a rounded tool. The movement of the tool is governed by a CNC machine. By this way the tool locally deforms the sheet through pure stretching deformation. In this research incremental forming experiments were carried out on Aluminum 1100 sheets to form a cone shape. Roughness was studied by varying the input parameters (tool speed, feed rate and lubricant). From the study, it was found that the surface roughness was improved as tool speed and feed rate increases. Also it was found that using grease improve the surface roughness compared with using the coolant oil.
