2-Axis Tool Strategy Applied on NC Lathe Machine to Manufacture Revolved Parts by Means of SPIF Process

ISF process is a promising flexible process that attracts several researches during the last decade. Applied on a CNC machine thin sheet are shaped through incremental plastic deformation trigged by a tool path programmed with a G-Code. This paper presents an experimental investigation on Single Point Incremental Forming applied on NC turning machine to manufacture revolved parts made of AA1050-H14 material. The idea is to use a 2-axis tool path strategy through the program of a paraxial roughing cycle used in machining to bore cylindrical parts. In fact, using this program, sheet metal can be shaped by incremental plastic deformation to the desired part. The effect of penetration increment, the shape of the final part on formability, appearance of cracks and the part finishing quality is analyzed. Results carried out show the efficiency of this tool strategy to manufacture parts usually manufactured through a 3-axis milling strategy in SPIF process. Certainly, SPIF applied in NC lathe gain the advantage of a rapid procedure and a low cost.
