Opis:
The use of hybrid machining methods for parts and devices production become more and more attractive nowadays. The paper presents results of modelling use of DPSS (Diode Pumped Solid State) pulse laser for intensification of electrochemical processes in machine part production. Application of DPSS pulse laser enables possibility to reach high level of localization in both machining and growth processes. Laser beam energy accelerates electrochemical processing, improves process localization and prevents other than the machined surface passivation. These conditions should improve electrochemical micro part precision of manufacturing by means of shape and dimensional accuracy in both machining and growth ECM processing.

Opis:
Electrochemical machining is an unique method of shaping in which, for optimal parameters tool has no wear, surface layer properties after machining are similar to the core material and surface quality and accuracy increase together with material removal rate increase. Such advantages of electrochemical machining, besides of some ecological problems, create industry interest in the range of manufacturing elements made of materials with special properties (i.e. turbine blades of flow aircrafts engines). In the paper the nowadays possibilities and recent practical application of electrochemical machining in aircraft have been presented.

Opis:
One of the research and development trends in nowadays manufacturing technology is integration of different manufacturing techniques into single machine tool. In the first part of the paper possibilities, goals, reasons and advantages of thermal and electrochemical interaction have been characterized. As literature review indicates such a connection can be realized as sequential or hybrid machining. The second part of the paper focuses on detailed analysis of laser assisted electrochemical process. For this purpose, the mathematical model of workpiece heating has been developed. Based on obtained results and literature review possibilities of technical realization and potential application have been discussed.

Opis:
Recent dynamic development of abrasive hybrid manufacturing processes results from application of a new difficult for machining materials and improvement of technological indicators of manufacturing processes already applied in practice. This tendency also occurs in abrasive machining processes which are often supported by ultrasonic vibrations, electrochemical dissolution or by electrical discharges. In the paper we present the review of new results of investigations and new practical applications of Abrasive Electrodischarge (AEDM) and Electrochemical (AECM) Machining.

Opis:
In the first part of the article the review of ceramic materials drilling possibilities was presented. Among the described methods special attention is paid to electrodischarge drilling. This process have especially been predicted for machining difficult-to-cut electrically conductive materials. The second part consist of the results analysis of electrodischarge microdrilling of siliconized silicon carbide. The experiment involves the impact of current amplitude, discharge voltage and pulse time on the hole depth, side gap, linear tool wear and mean drilling speed. The results shows that electrodischarge drilling is a good alternative when machining inhomogeneous ceramic materials and gives possibility to drill high aspect ratio holes with relatively high efficiency (the drilling speed >2 mm/min).

Opis:
W artykule przedstawiono koncepcję elektrochemicznej intensyfikacji procesu mikroskrawania. Wprowadzenie oddziaływań elektrochemicznych w warstwie powierzchniowej przedmiotu obrabianego umożliwia zmniejszenie wytrzymałości oraz twardości usuwanego materiału, co w efekcie powoduje obniżenie sił skrawania i zmniejszenie deformacji narzędzia oraz przedmiotu obrabianego. Prowadzi to do poprawy wskaźników technologicznych obróbki, umożliwiając rozszerzenie operacji mikroobróbki mechanicznej na wykonywanie struktur 3D m.in. operacjami mikrotoczenia, mikrowiercenia czy mikrofrezowania.
In group of methods worked out for machining technological equipment, MEMS parts, functional prototypes and tools for micro-casting and micro-forming special attention is paid for application of microcutting and unconventional processes. The recent development is focused on 3D-shaped surfaces manufacturing. In case of microcutting the main problem during machining is connected with size effect. Significant forces in machining area limit microcutting process application to machine 3D parts made of soft materials and dimensions > 50 žm. One of effective methods to overcome these problems and achieves high performance for micromachining process is combining various physical and chemical processes into one machining process, defined as hybrid machining. One of the possibilities to decrease cutting forces is to decrease the mechanical properties by workpiece surface layer electrochemical passivation before or during cutting process. Between workpiece and additional electrode the electrolyte is supplied. When electrolyte pH and voltage are properly selected on the workpiece surface the thin oxide layer occurs. This layer is fragile and softer than core material, so can be easily removed with relatively smaller cutting forces, what increases tool life, decrease probability of tool damage, and increase accuracy of shaping by decreasing tool and workpiece deformation.

Opis:
In the work results of research on electrodischarge machining (EDM) of titanium alloy Ti10V2Fe3Al with (α + β) structure were presented. Preliminary heat treatment of samples allows to obtain different morphology and volume fraction of the α phase. The main goal of research was to assessment of the material microstructure impact on EDM technological factors (ie. material removal rate, tool wear) and morphology of technological surface layer. Electrodischarge machining is alternative and increasingly used method of titanium alloys machining. Research allowed to indicate the possibilities and limitations of use EDM in this area. It is especially important in the aspect of parts produced for aircraft industry and related requirements for the technological surface layer quality.
