The lack of uniformity of the deformations and the degree of deforming in case of orbital deformation

Abstract

Abstract. The degree of deformation and the lack of uniformity of the deformations are two important factors orbital deformity. The degrees of deformation in the case of orbital oscillating deformation between 40 and 70%, is much higher than in conventional methods. Two other important parameters that may change unevenness strains are axial force and advance. Their influence can be seen from the diagrams unevenness, and hence the higher the value of these parameters is reduced unevenness strains.

“…In metal processing by plastic deforming, one of the processes that imposes greatly nowadays in the direction of obtaining parts with a specific form as close to the finished product form as possible, directing pressure due to deformation in certain directions during convenient in relation to the geometry of the work piece, is defined as orbital plastic deformation. [1], [2] Focusing the plastic deformation effort in a limited volume and its displacement volume subjected to plastic deformation draw in itself, besides the possibility of routing the deform state on the imposed work piece's geometry directions, a 5…20 times reduction of the workforce and an rise in the deforming degree [2], [3]. Orbital deformation it is non-conventional technology like water jet cutting [4], [5], rapid prototyping [6], rapid tooling [7].…”
