Highly Efficient Milling on the Example of Selected Machining Strategies

Abstract

The pursuit to achieve a broadly defined optimisation of the manufacturing processes imposes the use of the increasingly innovative machining methods. The increase of the machining efficiency, assuring a high surface quality as well as precision of dimensions and shapes, necessitates the search for new methods to meet the demanding requirements, apart from the development of materials used for the working parts of tools, wear-resistant coatings or improvement of the cutting tool point geometry. One of the methods to improve forming by machining is the optimisation of the machining strategy during the manufacture of the components having complex shapes. The progress in this field is particularly noticeable along with development of the software for machining on multi-axis machines. This article presents the results of tests for the impact of machining strategy on passive force, cutting torque, material removal rate, topography of the obtained surface and the shape of chip resulting from the aluminium alloy milling. The tests were performed by comparison of the classic strategy available in the NXCAM system to the iMachining technology.

Prediction of QCE using ANN and ANFIS for milling Alloy 2017A

“…Most researchers who have worked on surface quality as a function of the tool path have used a single machining feature in their studies. Examples of this claim are the work of Zaleski et al 11 and Ali et al 12 Indeed the use of interacting features with a set of tool paths can lead to logic of the choice of surface quality. On the other hand, an overlay of tool paths when machining Fi features can modify the surface texture of the machined part.…”

Effect of the Geometry of Thin-Walled Aluminium Alloy Elements on Their Deformations after Milling

“…In such cases, it is necessary to take into account the anisotropy of mechanical and structural properties in individual directions in relation to the rolling direction. Furthermore, large quantities of chips, accounting for over 95% of a given semifinished product, imply the need to resort to high performance cutting and high speed cutting [12,13], which fit into the trend of reducing manufacturing costs via a faster removal of machining allowances than observed in traditional methods [14][15][16]. At the same time, taking into account the thin walls and dimensions of the manufactured elements, the application of, e.g., plastic working is practically impossible.…”
