“…Over the last few years, new strategies for highspeed roughing have been introduced that offer significant increases in metal removal rates and provide much shorter machining times [3][4][5][6][7]. In paper [8], six different tool path strategies have been investigated on the surface finish and machining time of a rectangular cavities of ESR Stavax material.…”

In the article the technology of high-speed milling was observed as a key to the most promising methods of engineering products machining. It is indicated that the correct choice of the strategy for moving the cutting tool in the manufacture of products is the basis for ensuring the desired surface quality of the workpiece and its high processing efficiency. A review of the work devoted to the diagnosis of high-speed processing strategies was performed. Based on the up-to-date knowledge of the physics of the process of establishing of a qualitative surface, the article proposes to consider a new technology of high-speed milling with half-overlap. As the main idea of this technology, it is suggested to consider the work of the deformation component of cutting process as the main component of the complex energy-intensive process of high-speed milling. In addition, the paper suggests a technique for estimating the productivity of machining by the method of high-speed milling with half-overlap. It is theoretically justified that the specific productivity of the proposed technology is quite high Q=12.5÷4.2 cm 2 /min and depends on the technological regimes. The place of technology of high-speed milling with half-overlap in the technological process of manufacturing details of any complexity was noted. The area of further research is indicated.

Original scientific paper Virtual manufacturing systems can provide useful means for products to be manufactured without the need of physical testing on the shop floor. As a result, the time and cost of part production can be decreased. The paper presents the influence of tool path trajectory on surface deviation geometry when finishing inclined surfaces. The aim of the study is to optimize the milling process taking into account the milling strategy. The research was focused on ball end finishing because it is well known that in plain cutting, in the centre of the flat mill the cutting speed is vc = 0 m/min. According to that, the surface roughness is influenced by the fact that in this area a friction process occurs and not a cutting process. Six types of tool trajectories were simulated and surface deviation was evaluated.

“…The paper concludes that cutting speed has main effect on surface quality beside other geometric and tool parameters. Pena et al [8] present 5 different tool strategies and analyses them from the point of view of surface roughness in the case of 6061 aluminium. Due to different Ra parameters, a correction factor is introduced which modifies the feed rate in order to ensure better surface roughness.…”

When machining free-form surfaces with a ball-end milling tool, the working tool diameter is constantly changing even if the tool path is constant. The reason is that the surface normal of the milled surface is continuously changing along the milling path. When the working diameter is changing, the cutting parameters also change. This variation effects the roughness homogeneity of the smoothed surface. Simultaneous five-axis milling solves this problem; however, the price and complexity of this technology can be a problem for some industrial sectors. In the paper, the geometrical background of a solution to this problem is presented for a 3-axis ball-end milling process for machining a free form surface. The paper provides the deduction of the theory by the use of homogeneous transformations. The geometrical problem of the cutting process is treated locally where the general machined surface is substituted at every point by its tangent plane. From the result of the presented method, a milling strategy can be formulated for ball-end milling that minimises the change in the momentary working diameter thus providing a more constant cutting parameter.
