Opis:
Commonly applied theories of self-excited vibrations in machine tools are prevailingly based on frequency domain analysis of linear models and are devoted in most cases only to evaluation of stability limits of strictly linear systems. In this way, the behaviour of more stable or more unstable systems cannot be studied and analyzed. Certain important nonlinear effects cannot be studied as well for limitations connected with classical representation of systems only in the frequency domain. Evaluation of stability by analysis of nonlinear systems in time domain has not been applied until now. The paper shows a new approach based on interpretation of the self-excited vibration systems as nonlinear servo-systems. With this approach, linear and nonlinear systems of any degree of stability can be studied by combination of frequency and time-domain methods. This can considerably contribute to better understanding of complex phenomena in various regimes and special situations.

Opis:
Prezentowany artykuł przedstawia wybrane zagadnienia związane z poprawą jakości frezowanych przedmiotów cienkościennych poprzez ograniczenie błędów procesu skrawania. Na wybranych przykładach przedstawiono sposoby zmniejszania błędów obróbki poprzez zastosowanie skrawania z podwyższonymi prędkościami (HSC), optymalizację parametrów skrawania oraz dobór odpowiedniej strategii obróbki. Do obróbki HSC posłużono się wysokoobrotowym wrzecionem z napędem pneumatycznym. Wykazano, że powierzchnie przedmiotów cienkościennych, frezowane z wysokimi prędkościami skrawania, charakteryzują się większą regularnością śladów obróbkowych oraz niższą chropowatością i falistością w stosunku do powierzchni obrabianych z klasycznymi parametrami skrawania. Rozważano naprężenia własne w WW wykonywanych przedmiotów. Wykazano też, że właściwy dobór parametrów skrawania pozwala uzyskać poprawne geometrycznie przedmioty cienkościenne.
Paper presents some problems concern with quality improvement of milling thin-walled parts through the cutting process error limitation. On the chosen examples the manners of cutting errors decreasing, relies on application of high cutting speed (HSC), cutting parameters optimization and proper cutting strategy selection are presented. HSC machining was performed with the help of a pneumatic high speed turbine. It was proven that surfaces of the thin-walled parts, milled with high cutting speeds are characterised by more regularity of cutting traces, lower roughness and waveness in relation to the surfaces machined with classical cutting parameters. Residual stresses in the upper layer of machined parts were considered. It also was proven that the proper cutting parameters selection permits the correctly geometrical thin-walled parts achievement.

Opis:
Machining center is the complex machinery, with high level automation and complicated structures, so there are lots of failures. When a random failure occurs, the failed machining center stops and causes a production line or even the whole workshop to stop functioning. The frequent failure leads to the low levels of reliability and production rate. In order to help users and manufacturers optimize maintenance policy to improve the reliability for machining center, this paper presents descriptive statistics of the failure data and develops the failure trend using power-law process, simultaneously establishes the routine inspection and regular inspection as well as the sequential preventive maintenance under maintenance cost constraints. The proposed model could be a useful tool to assess the current conditions, predict reliability and optimize the machining center maintenance policy.
Centrum obróbkowe to skomplikowany mechanizm o wysokim poziomie automatyzacji oraz złożonej konstrukcji, w związku z czym ulega licznym uszkodzeniom. Przy wystąpieniu przypadkowej awarii, uszkodzone centrum obróbkowe przestaje działać i powoduje zatrzymanie linii produkcyjnej a nawet całego oddziału produkcyjnego. Częste awarie obniżają poziom niezawodności oraz tempo produkcji. Aby pomóc użytkownikom i producentom zoptymalizować politykę utrzymania ruchu w celu poprawy niezawodności centrów obróbkowych, w niniejszym artykule przedstawiono statystyki opisowe dotyczące danych o uszkodzeniach i opracowano trend uszkodzeń w oparciu o proces spełniający prawo potęgowe. Jednocześnie ustalono zasady rutynowej inspekcji i okresowych przeglądów, jak również sekwencyjnej obsługi zapobiegawczej przy ograniczonych wydatkach na utrzymanie ruchu. Proponowany model może być użytecznym narzędziem dla potrzeb oceny aktualnych warunków oraz przewidywania niezawodności w celu optymalizacji polityki utrzymania ruchu centrum obróbkowego.

Opis:
The machining allowance variation is significant for the reliability of a part during the machining process. Usually, when the machining allowance of a part increases, the machining and production cost also increase. When the machining allowance decreases, the machining surface will have defects. The parts will produce manyscraps andreliability will decrease. The machining allowance of a part consists of multiple process machining allowances. To analyze the impact caused by machining allowance variation, the hidden quality loss and process machining allowance are combined through theprocess capability index (PCI). Then the asymmetric quadratic quality loss function (AQF) and quadratic exponential function (QEF) are used to analyze them. A prediction model of hidden quality loss of process machining allowance is proposed. On the premise that the quality characteristic value obeys normal function distribution, a numerical model is given and used to obtain process machining allowance-inherent reliability of the product. The actual case is used to compare and verify the two models.

Opis:
The article presents a review of research methods for the cutting process using the abrasive waterjet machining. The focus was on assessing the possibility of monitoring the cutting process based on the parameters available for direct or indirect measurement. An attempt was made to evaluate their influence on the machined surface after treatment with the abrasive cutting method. These parameters include, inter alia, vibrations of the cutting head, force effects on the head support structure and the material to be cut, dynamic properties of the machine support structure and high pressure pumps. As part of the own research, correlation was sought for the registered selected signal characteristics with the cutting parameters responsible for the process course and the parameters related to the obtained machined surface. For this purpose, a model of the deflection angle of the abrasive waterjet was proposed, which qualitatively determines the condition of the surface after cutting. The angle of inclination of the abrasive waterjet is determined on the basis of the registration of the feed force during the cutting process. The research on surface topography was extended by an attempt to determine the surface roughness by measuring vibrations and looking for correlation between the displacements of the cutter head tip and the measured roughness height profile. These tests also allowed the identification of selected frequencies that clearly result from the set parameters of the cutting process. The last stage of the research was to monitor the cutter head behaviour using a deformation sensor as another concept for recording the forces during the cutting process. Finally, the proposed methodology was characterized in the context of its usefulness in the on-line process monitoring and supervision system.

Opis:
Next-generation of High-Speed Machining (HSM) systems demand advanced features such as intelligent control under uncertainty. This requires, in turn, an efficient administration and optimization of all system's resources towards a previously identified objective. This work presents an optimization system based on Markov Decision Process (MDP), where an intelligent control guides the actions of the operator in peripheral milling processes. Early results suggest that MDP framework can cope with this application, yielding several benefits, which are discussed in detail. Future work will address the full integration of the developed optimization scheme within a commercial machining center.

Opis:
This paper will introduce a novel methodology for the performance evaluation of machining strategies of engine-block manufacturing. The manufacturing of engine components is vital to the automotive and vehicle manufacturing industries. Machining are a critical processes in the production of these parts. To survive and excel in the competitive manufacturing environment, companies need to improve as well as update their machining processes and evaluate the performance of their machining lines. Moreover, the lines and processes have to be robust in handling different sources of variation over time that include such examples as demand fluctuations, work-piece materials or even any changes in design specifications. A system dynamics modelling and simulation approach has been deployed to develop a methodology that captures how machining system parameters from the machining process are interacted with each other, how these connections drive performance and how new targets affect process and machine tool parameters through time. The developed model could provide an insight of how to select the crucial machining system parameters and to identify the effect of those parameters on the output of the system. In response to such an analysis, this paper provides (offers) a framework to examine machining strategies and has presented model that is useful as a decision support system for the evaluation and selection of machining strategies. Here a system dynamics methodology for modelling is applied to the milling operation and the model is based on an actual case study from the engine-block manufacturing industry.

Opis:
In the era of Industry 4.0, the digitization of production processes is one of the important elements contributing to the reduction of uncertainty related to the implementation of new production methods. The worldwide epidemic situation and its constraints have resulted in supply chain continuity problems. These problems make enterprises look for the possibility of producing products that they need at the moment and which they cannot obtain from the market. In special cases, this may also apply to spare parts necessary to maintain the continuity of production. The main reason for research on comparing production processes is meeting the challenges related to the pandemic situation and problems in maintaining timeliness, flexibility, and continuity of the supply chain. The first stage of the research was to visualize the course of the process and determine the lead times for both production methods. For further analysis, a digital process model was used to compare the hybrid and the classical method to check the viability of the interchangeability of methods for the production process of the flange part. The interchangeability of production methods was dictated by problems related to the supply of components for the execution of orders. The article simulates the model for unit and small-lot production in batches of 10 and 100 pieces, considering such aspects as: order completion time, energy consumption of the process, production costs, taking into account the classic and hybrid methods. The conducted research was aimed at determining the profitability of the production of flange-type products by means of classical processing and hybrid and checking the interchangeability of production methods in accordance with quality requirements as well as reducing uncertainty with the implementation of new production systems in changing market conditions. The simulations show that the use of hybrid production is recommended for unit production. In the case of small-lot production, already with 10 items, production in the traditional process is 21% cheaper, and for the production of 100 items, the cost of traditional production is reduced by 33% compared to hybrid production.

Opis:
Sawing is often the first work step in the metal cutting production chain. Especially for larger workpieces, bandsawing is used for this purpose. Nevertheless, studies on sawing have led a niche existence in the research landscape for a long time. However, as a result of the optimization of manufacturing processes in terms of economic efficiency, bandsawing is increasingly becoming the focus of research, since there are still saving potentials here. The aim of this paper is to investigate the extent to which the bandsawing process can be influenced by active, low-frequency vibration superimposition in the feed direction. First, analogue tests were carried out and parameter combinations were determined which have a positive influence on the process. Subsequently, these parameter combinations were investigated on a real sawing machine with an excitation unit, analysing the extent to which the results from the analogue tests could be transferred to the real process.

The article presents the results of the simulation studies concerning the impact of random production interruptions on the efficiency of multi-spindle machining centers. Four different machining center configuration models were developed using a dedicated class of stochastic Petri nets. In addition to the number of machine spindles, the number of simultaneously mounted parts, loading time of parts, their machining time, and reliability parameters regarding the frequency of machine interruptions caused by random factors were also taken into account as model parameters. A series of virtual tests was carried out for machining processes over a period of 1000 hours of operation. Analysis of the results confirmed the purpose of conducting simulation tests prior to making a decision regarding the purchase of a multispindle milling center. This work fills the existing research gap, as there are no examples in the technical literature of evaluating the effectiveness of multi-spindle machining centers.

Artykuł omawia zagadnienia związane ze skutecznością procesu wycinania elektroerozyjnego WEDM (Wire Electrical Discharge Machining) i dokładnością kształtu wykonywanych przedmiotów. Badania wstępne służące doborowi parametrów procesu cięcia przeprowadzono na próbkach ze stali HS 18-0-1 o wymiarach 10x10mm oraz stali nierdzewnej o grubości 3mm. W badaniach poświęconych dokładności kształtu wycięto w blasze ze stali nierdzewnej dwa cylindry o średnicy 30mm i grubości 15,43mm. Dodatkowo, dla jednego z otworów pozostałych w próbce po procesie WEDM wykonano obróbkę wykończeniową. Dokonano pomiarów odchyłek okrągłości i błędów walcowości otworów i wyciętego cylindra, przy pomocy przyrządu pomiarowego Talyround 365. Analiza tych wyników wykazała wyraźną poprawę dokładności kształtu dzięki obróbce wykończeniowej. Zaobserwowano też różnice wymiarowe w mierzonych płaszczyznach. Było to spowodowane, prawdopodobnie specyficzną charakterystyką procesu WEDM. Produkty odpadowe erozji, gromadziły się bowiem na bazowej powierzchni walców, co powodowało większą intensywność wyładowań w tym obszarze.
The paper presents efficiency of WEDM process (Wire Electrical Discharge Machining). Preliminary tests, to check the effectiveness of generator, were performed with specimens made of HS 18-01 steel and stainless steel. Two cylinders with diameter 30mm and thickness 15.43mm were cut. Additionally, for one hole, the finishing cut was performed. The hole roundness as well as cylindricity accuracy were measured by means of Talyround 365. The results for the hole number 1 (without finishing cut) and number 2 (with finishing cut) were analyzed. The hole number 2 showed better results. A dimension difference in measured planes was noticeable. It was probably caused by specific operation of WEDM. Waste products of erosion which gathered in the base area of cylinders resulted in greater intensity of discharges.

Opis:
Turning machining is a complex process in which many variables can influence the desired results. Among those variables, cutting tool vibration and cutting force greatly affect the precision of the workpiece and the tool life. While the tool vibration and cutting force in feeding are primarily determined by cutting speed, feed rate, and depth of cut as well as the dynamic characteristics of the machining system. This paper presents an analytical modeling approach to investigate the effects of machining conditions based on the governing equation of the machining system. The machining behaviors under different conditions were simulated by Simulink block diagram. Basically, the cutting speed is considered the parameter dominating the vibration behavior and hence is served as the primary input for the simulation. The effectiveness of constant surface speed (CSS mode) or function G96 in the turning process was further examined through comparisons of the variations of vibration and cutting force generated in feeding with different conditions.

Opis:
The study aimed to develop a system supporting technological process planning for machining and 3D printing. Such a system should function similarly to the way human experts act in their fields of expertise and should be capable of gathering the necessary knowledge, analysing data, and drawing conclusions to solve problems. This could be done by utilising artificial intelligence (AI) methods available within such systems. The study proved the usefulness of AI methods and their significant effectiveness in supporting technological process planning. The purpose of this article is to show an intelligent system that includes knowledge, models, and procedures supporting the company’s employees as part of machining and 3D printing. Few works are combining these two types of processing. Nowadays, however, these two types of processing overlap each other into a common concept of hybrid processing. Therefore, in the opinion of the authors, such a comprehensive system is necessary. The system-embedded knowledge takes the form of neural networks, decision trees, and facts. The system is presented using the example of a real enterprise. The intelligent expert system is intended for process engineers who have not yet gathered sufficient experience in technological-process planning, or who have just begun their work in a given production enterprise and are not very familiar with its machinery and other means of production.
