Statistical Tolerance Analysis of Gears by Tooth Contact Analysis

Jérôme Bruyère; Jean-Yves Dantan; Régis Bigot; Patrick Martin

To analyze the influence of geometrical variations of parts on functional characteristics, a powerful way consist to simulate its geometrical behaviour. For gears, a specific method based on Tooth Contact Analysis is developed to evaluate influence of intrinsic and situation deviations of pinion and wheel on the assembly. Moreover, a statistical analysis allows to determine probability distribution of the functional characteristic - cinematic error for a list of random geometrical deviations.

Experimental investigation of thixoforging tubes

Eric Becker; Régis Bigot; Florian Baratto; Jean-Baptiste Croué; Olivier Gyss

The fields of industrial applications of the thixoforging applied to steels remain to be set as more conditions as the most suitable materials, the dimensional limits, the limitations associated with tooling, the heating means, etc.To thixoforging in good conditions, the steels must have low melting temperatures and a low temperature slope to achieve complete melting that allows the use of less specific heating means.This article presents the results of thixo-extruded tubes of C05 steel grade, a low carbon steel grade. These experimental tests use flashless forging process on screw press. In this work, a geometrical parts analysis shows a good dimensional performance of thixoforging process. Another feature of thixoforging these tubes is that it pushes the dimensional limits of the thickness of the can wall compared with the case of conventional forging.The fields of industrial applications of the thixoforging applied to steels remain to be set as more conditions as the most suitable materials, the dimensional limits, the limitations associated with tooling, the heating means, etc.To thixoforging in good conditions, the steels must have low melting temperatures and a low temperature slope to achieve complete melting that allows the use of less specific heating means.This article presents the results of thixo-extruded tubes of C05 steel grade, a low carbon steel grade.

Impact of tool wear on cross wedge rolling process stability and on product quality

Catalina Gutierrez; Laurent Langlois; Cyrille Baudouin; Régis Bigot; Eric Fremeaux

Cross wedge rolling (CWR) is a metal forming process used in the automotive industry. One of its applications is in the manufacturing process of connecting rods. CWR transforms a cylindrical billet into a complex axisymmetrical shape with an accurate distribution of material. This preform is forged into shape in a forging die. In order to improve CWR tool lifecycle and product quality it is essential to understand tool wear evolution and the physical phenomena that change on the CWR process due to the resulting geometry of the tool when undergoing tool wear. In order to understand CWR tool wear behavior, numerical simulations are necessary. Nevertheless, if the simulations are performed with the CAD geometry of the tool, results are limited. To solve this difficulty, two numerical simulations with FORGE® were performed using the real geometry of the tools (both up and lower roll) at two different states: (1) before starting lifecycle and (2) end of lifecycle. The tools were 3D measured with ATOS triple sc...
