Optimum Cutting

According to the principle producing the cutting track of cutter, to study the influence of the cutting track of cutter on the process of high speed ball-end milling, the single-factor models for evaluating the cutting track of cutter are established. Adopting four kinds of the typical cutting track of cutter, the experiment of high speed ball-end milling is processed. The model of multi-ply fuzzy comprehensive evaluation for the cutting track of cutter is established, fuzzy comprehensive evaluation for the cutting track of high speed ball-end milling cutter is accomplished by the application of fuzzy mathematics theory. Results show that the cutting contact curve of cutter affects directly the process of high speed ball-end milling, fuzzy and uncertain properties exist in the evaluation for the cutting track of cutter. The optimum cutting track can be selected by multi-ply fuzzy comprehensive evaluation for the cutting track of high speed ball-end milling cutter.

Abstract The analysis of the surface topography in ball end milling is an objective studied by many researchers, several methods were used and many combinations of cutting conditions and machining errors are considered. In the milling tool paths the trajectories presents a points of changing direction where the tool decelerates before and accelerates after respecting the velocity profiles of the machine. In this paper, we propose experimental investigations of the effect of the kinematic behavior of the machine tool on the surface quality. A poor topography and roughness are remarked on the deceleration and the acceleration zones compared to the stationary zone.

Cutting Parameters Optimization

High-speed cutting is a complexity and uncertainty process .The cutting parameters optimization is ambiguous. In this paper, based on the orthogonal experiment of high-speed milling aluminum alloy 7475, we use fuzzy comprehensive evaluation to optimize the parameters high-speed milling of aluminum alloy 7475 in the indication of surface roughness, cutting force, material removal rate. We have got cutting parameters optimal that is highly processing quality and productivity. Compared optimal results with orthogonal experimental results, we found that the optimal result is reliable. The study shows that fuzzy comprehensive evaluation method can optimize the parameters of high-speed milling of aluminum alloy 7475 accurately. This method has also a good application effect to other materials and great significance to guide actual production.

Ball End Milling

The ball end milling process, commonly used for generating complex shapes, involves continuous variation in the uncut chip dimensions, which depends on the cutter geometry and the machining parameters. The proposed analytical model evaluates the undeformed and the deformed chip dimensions including chip length, width and thickness. The undeformed and deformed chip dimensions, is a function of cutter rotation angle, instantaneous cutter radius, helix angle, and other processing parameters. The surface quality, in the form of surface roughness, during high-speed ball end milling of Inconel 718 is also analysed in this paper.
