Abstract

The local plastic deformation of a sheet, using a unique tool by different controlled path strategies with the absence of punch and die is called Single Point Incremental Forming (SPIF). It is an environmental friendly sheet forming process compared to stamping, where the manufacturing and disposal of dies are creating a huge environmental footprint. In SPIF, the forming tools are mainly kind of a metal spike with a spherical or flat end on top of it, where the diameter of the tool tip is 10 mm in average. In this study, the effects of different parameters of SPIF on the hardness of aluminium alloy sheet 1100 have been carried out experimentally and studied. The analysis of the test results has shown that hardness remarkably increases by increasing the tool speed. Furthermore, the increase in the feed rate leads to an increase in hardness. Besides, the use of various greases with not-environmental coolant oil effects presented that hardness increases using coolant oil and decreases using grease when applying the same feeds.
