Abstract

Nowadays, by technology progression (CAD), controlling tools movement in Incremental forming process, caused improvement of forming function mechanism-manufacturing symmetrical and asymmetrical pieces, as by determination of an ideal direction pattern and the way of contacting tools with pieces, Caused improvement of forming behavior in sheet metals and geometry firming of complicated forms, was used in airspace and auto-making industries. In present research Two-point incremental Forming of sheet metal was studied experimentally by investigating priority of tool movement in negative and positive limit of geometrical profile in central cavity die. Moving pattern of tools rotationally and spindle axis constant of system (Z) around die geometrical profile, was investigated for positive and negative forming. Used sheet metal in this research is 1050 aluminum with 15mm thickness. The results of die geometrical profile showed that critical area with maximum thinning led to tearing of all samples of sheet metals in negative forming limit while moving pattern of rotator caused decrease of tearing rate and thinning relative to constant tools in sheet metal. Maximum rate of deep, formed in negative critical area of die geometrical profile, occurrence time of tearing in sheet metal Z=-25. 2mm in rotational case of tools with first negative and second positive forming pattern, is the most ideal two-point forming case in central cavity pieces
