1	Analysis of the Cross-Wedge Rolling Process of Toothed Shafts Made from 2618 Aluminium Alloy显示文摘The paper presents the results of a thermo-mechanical analysis of the rolling two stepped shafts.One of the shafts has a toothed step with skew teeth,while the other has a worm winding in the shape of a trapezoidal screw.The shape of the rolling tools resembles that of the tools used in the Roto-Flo rolling method;yet unlike in Roto-Flo,the shafts are hot-rolled and no centres are used to stabilize the position of the workpiece during the forming process.For the calculations made with use of the DEFORM-3D process simulation system it has been assumed that the rolled shafts are made from 2618 aluminium alloy.As a result of the calculations made,it has been found that the toothed stepped shafts can be formed in one pass by means of the cross rolling process.Additionally,the temperature and strain distribution in the rolled product have been determined as well as some data concerning the forces which are necessary for the rolling process have been obtained.

10	Numerical Analysis of Unconventional Forging Process of Hollowed Shaft from Ti-6Al-4V Alloy显示文摘This paper presents theoretical analysis of unconventional forging process of hollowed shaft from Ti-6Al-4V alloy in a three-slide forging press.This method in comparison with other metal forming methods allows for obtaining of hollowed products.The designed process is verified theoretically by means of numerical simulations based on finite element method with assumption of 3D state of strain.The following factors are considered in the analysis:material flow kinematics,strain distribution,temperature distribution and force of process.On the basis of results,it is stated that the application of designed technology allows for obtaining of a product of assumed quality.A comparison is made between material consumption in analyzed process and material consumption in typical metal forming methods,also in used at present technology of shaft manufacturing by machining only.It is stated that the application of forging in the three-slide forging press allows for a considerable decrease of manufacturing costs due to material savings and decrease of labor consumption of operations at finishing.
