RESEARCH ON THE FORMING ANGLE OF A1050-H14 ALUMINUM MATERIAL PROCESSED BY USING SINGLE POINT INCREMENTAL FORMING TECHNOLOGY (SPIF)

Abstract

Single Point Incremental Forming – SPIF is the recent manufacturing process of metal sheet forming by drafting a non-cutting edge sphere-tip tool on a clamped metal sheet. The formability of metal sheet in SPIF is considered by the forming angle (y)- the maximum draft angle so that the material is not torn. The experimental research on A1050-H14 aluminum sheet on Bridge Port VMC500-16 CNC milling machine in C1 workshop of the HCMUT in order to find out the regression equations to predict the maximum forming angle in the relation with four most important technology parameters in SPIF: size of the step down z, forming feed v_xy, spindle speed n, forming tool diameter d.
