Analysis of Hardfacing and Milling of Forging Die by CAx Technologies

Abstract

The contribution is dealing with the forging die renovation by hard facing and following machining processes. Deviation of weldment are creating during all types of welding technologies. Shape deviation determining is necessary to purpose of machining and welded layers control quality. The optical scanner ATOS II TripleScan was used to evaluate a quality and deformations of hard facing layers created by fusion welding. Obtained 3D model of the die was used not only for evaluation of quality but also to use as workpiece for CAM simulation of roughing process. The usage of obtained 3D model by ATOS II TripleScan indicate a significant improvement of machining time based on CAQ technology.

Modeling and multiple optimization in face milling of hardfacing welding applied steel: Force, roughness, power

“…As a result of the research, it was emphasized that an optical scanner is a convenient technique for measuring the size and deformation of weld joints, improving the milling process, and material analysis. 21 Poonnayom et al 22 investigated the machinability of hardfacing weld metal applied on JISS50C steel in dry and wet conditions in terms of microstructure, chip and wear properties, and surface roughness. In the study in which TiN+TiCN+Al 2 O 3 coated carbide tools were used, more tool wear was observed in the wet environment than in the dry condition, since sufficient coolant oil droplets could not enter the chip-tool interface.…”

Role of preplaced silicon on a TIG processed SiC incorporated microalloyed steel

“…An alternative source of surface melting to lasers is by the more economical tungsten inert gas (TIG) process, which received some early attention for titanium alloys [12][13][14]. High tonnage applications in agriculture, mining, civil engineering and transportation for example [15][16][17][18][19], require relatively cheap methods of surface engineering of steels, to develop a combination of good toughness and abrasive wear resistance. The application of TIG to incorporate ceramics, such as TiC [20][21][22] and SiC particulates [23][24][25] into the surface regions of steels has been investigated using a range of energy inputs and ceramic concentrations.…”

Influence of Finish Milling Strategies on the Tool Wear

“…In the major part of these publications, flank wear was the main criterion for evaluation of experiments. The article fastens on (15) which dealt with the roughing milling strategies for the same shape and material of workpiece.…”
