“…The surface roughness of the machined surfaces can be affected by the kinematic-geometric parameters, frictional effects in the tool-work material inter-face [1], process stability [2], plastic-elastic deformations of work material induced by the ploughing mechanism [3,4], as well as the thermal phenomena in the cutting zone [5][6][7]. However, one of the most significant factors affecting milled surface quality is tool-work piece relative displacement (vibrations) [8].…”

Abstract. This paper is focused on the multi criteria optimization of precision ball end milling process of hardened 55NiCrMoV6 steel. The proposed method enables the selection of optimal input parameters which affect the minimization of cutting forces and vibrations signals, as well as the maximization of process efficiency. The experiment includes the measurement of forces and vibrations during the milling tests with variable input parameters. Ultimately, the optimization of the ball end milling process with the application of response surface method is carried out.

“…In the last time a lot of attention is directed to non-ferrous alloys such as nickel alloy. Also, the emphasis is put on the machinability improvement of difficult-to-cut materials [13][14]. The group of difficult-to-cut materials undoubtedly include nickel alloys such as Waspaloy [9][10] or alloys reinforced with SiC [1,[3][4][5], WC [7,[15][16] particles.…”

Abstract. In the aviation industry the nickel-based superalloys such as Waspaloy are very often used. Conventional machining of this alloys is difficult and expensive. Therefore a Waspaloy requires the new techniques for machining like e.g. Laser Assisted Machining (LAM). New development directions of mechanical engineering are focusing on this type of hybrid machining, where materials are heated and cut in the single process. LAM enables increasing the material machinability through the increase of its temperature in cutting zone. It is assumed that additional increased temperature in the contact zone between surface of material and cutting tool causes the increase of machinability. This paper presents the results of laser heat treatment process on Waspaloy material. The influence of laser heat treatment parameters on the surface condition and selected properties of Waspaloy were analyzed. Laser heat treatment was carried out using diode laser with nominal power equaled to 3.0 kW. The laser beam power density and its scanning laser beam velocity were analyzed. In the first step the single laser tracks were prepared and analyzed. In the second step the multiple laser tracks were prepared. The special attention was directed on change in microstructure. It was found that the laser heat treatment have significant influence on microstructure. The dendritic microstructure of Waspaloy which is characterized by a lower microhardness, causes better machinability of this material.

“…The chip material's removal during machining processes is accompanied by plastic-elastic deformations of work material induced by the ploughing mechanism [1,2], as well as the thermal phenomena in the cutting zone [3][4][5]. The appearance of these phenomena is strictly correlated with the generation of cutting forces and vibrations, which in turn can significantly affect the deterioration of the machined surface quality [6,7].…”

Abstract. In this paper the monitoring method of turning process of combustion engine piston's cylindrical surface is proposed. During this process, the PCD diamond tool cuts the piston's cylindrical surface with the 3 grooves. The first groove is made in the cast iron insert. In case, when the machining allowances are selected inappropriately, the tool cuts the cast iron insert and consequently generates the reject. The proposed monitoring system based on vibration signals analysis enables the detection of these critical situations and react, in order to maintain the production quality.
