• Abstract:

  This study aims to evaluate

  the behavior of zinc sheets using single point

  incremental sheet forming process under four

  different lubricants. This stamping technique

  has gained prominence because it allows

  forming in CNC machining centers, without

  the need for specialized tooling, allowing the

  process of sheet forming at a relatively low

  cost. Part geometry was generated in a CAD/

  CAM software and plates were fixed in the CNC

  machine through a clamping device. Parameters

  were set according to works of previous authors

  in stamping of zinc and stainless steel parts.

  Roughness tests were conducted to evaluate

  surface quality, and material mechanical

  properties were assessed through tensile

  tests. Results indicated that the zinc covered

  steel used possess good formability. Besides a

  slightly better surface quality was observed for

  lubricant containing graphite.
