This work deals with problems of tool axis inclination angles in ball-end milling. Tool axis inclination angle contributes to improvement of functional surface properties (surface integrity surface roughness, residual stress, micro hardness, etc.), decreasing cutting forces and improving production. By milling with ball-end milling tool, using standard way of cutting, when work piece and cuttin...

In this paper, the straight flute end-milling cutter used for machining of Al-Si-Mg-Fe alloy work pieces was investigated. The machining processes could induce residual stresses that enhance greatly the performance of the machined component. Machining residual stresses correlate very closely with the cutting parameters. In the experiments, the residual stress on the surface of workpiece was mea...

This paper uses the artificial neural networks (ANN’s) approach to evolve an efficient model for estimation of cutting forces, based on a set of input cutting conditions. Neural network algorithms are developed for use as a direct modeling method, to predict forces for ball-end milling operations. Prediction of cutting forces in ball-end milling is often needed in order to establish automation ...

This paper focuses on the mathematical modeling for 5-axis milling with a filleted end mill. Several coordinate systems are introduced to describe the relationship between a cutter orientation and a machined surface. Then, a cutting point on a cutting edge is geometrically formulated as an integrated form of some expressions. The fundamental simulations based on the modeling were implemented to...

In this paper, an attempt has been made to design an computational intelligence technique based expert system using Adaptive Neuro-Fuzzy Inference System (ANFIS) for predicting surface roughness in end milling of Inconel 718. Two different types of membership functions are adopted for analysis in ANFIS training and compared their differences regarding the accuracy rate of the surface roughness ...

This paper presents the finite element analysis to study the stress distribution of nickel based superalloy HASTELLOY C-2000 in end milling operation. A commercial finite element software was used to develop modeling and analysis the distribution of stress components in the machined surface after end milling of HASTELLOY C-22HS using coated carbide tools. The friction interaction along the tool...

(Mo1-x-Crx)Si2 composite powders were successfully synthesized by ball milling of Mo, Cr and Si elemental powders. Effects of the Cr content, milling time and annealing temperature were investigated. X-ray diffraction (XRD) was used to characterize the milled and annealed powders.
