Abstract

This paper attempts to represent a case of calculating of the energy power that is consumed by CNC milling machine when manufacturing via forming membrane metal sheet by SPIF (Single Point Incremental Forming), the recent manufacturing process of metal sheet forming by drafting a no cutting-edge spheric tip tool on a clamped metal sheet. The calculation is based on the disclocation, the crystal plasticity and the slip of lattices inside the structure of the deformed metal. In the while time there is a series of empirical species of 24 groups batch of workpieces that were also machined by CNC milling machine Bridge Port VMC500, CAD/CAM Lab., FME of HCMUT for checking this calculation on consumed power.
