Opis:
The paper presents the results of simulation research on buffer space allo-cated in a flow line and operation times influence on the throughput of a manufacturing system. The production line in the study consists of four stages and is based on a real machining manufacturing system of a small production enterprise. Using Tecnomatix Plant Simulation software, a simulation model of the system was created and set of experiments was planned. Simulation experiments were prepared for different capacities of intermediate buffers located between manufacturing resources and op-eration times as input parameters, and the throughput per hour and aver-age life span of products as the output.

Opis:
Tapping is an extensively employed manufacturing process by which a multi-teeth tool, known as a tap, cuts a mating thread when driven into a hole. When taps are new or slightly worn, the process is under control and the geometry of the resulting threads on the workpiece is correct. But as the tap wear increases, the thread geometry deviates progressively from the correct one and eventually the screw threads become unacceptable. The aim of this paper is to outline the development of a statistical process control strategy for decision making based on data coming from the current signal of the tap spindle for assessing thread quality. It could operate on line, and indicates when the tap wear is so critical that, if the process were continued, it would result in unacceptable screw threads. The system would be very cost-effective since the tapping process could be run without any operator intervention.

Opis:
Recent development in the field of numerical modelling of innovative manufacturing processes, in which nanolayered materials can be produced, is presented in the paper. Combination of the Angular Accumulative Drawing, continuous wire drawing and wire flattening were used to produce thin nanolayers that will be used for subsequent production of nanolayered metal strips using Accumulative Roll Bonding process. Proposed methodology combines microstructural aspects of deformation such as strain-induced precipitation processes and development of dislocation substructures. Additionally, multiscale modelling approach based on the 3D Digital Materials Representation was utilized to support experimental research and to investigate inhomogeneous material behaviour during deformation. Proposed methodology provides a possibility of forming materials, which are e.g. difficult to form in a conventional manner. Advantages and limitations of the proposed model are summarized and discussed with respect to its potential application to precipitation strengthened bcc nanolayered materials.

Opis:
The paper presents the issue of production processes improvement in foundries in the area of finishing treatment of iron casts manufactured on automated foundry lines with vertical or horizontal mould division. Due to numerous factors which influence the efficiency of the processes, multi-criterion assessment tools were proposed in order to select the optimal solution for the assumed criteria. After determining the criteria weight using the Saaty method, a simulation experiment was designed and carried out which presents possible scenarios of casts finishing treatment operations. Basing on experiment reports from a computer model, particular solutions were evaluated using the Yager’s method. The evaluation of the experiment results was performed by experts who assessed different options according to each of the criteria adopted. After the establishment of the total standardized ratings by averaging the scores given by individual experts, the final decision was generated. Using the presented method, the best solution was chosen from among the analyzed scenarios.

Opis:
The scope of this work focuses on the aspects of quality and safety assurance of the iron cast manufacturing processes. Special attention was given to the processes of quality control and after-machining of iron casts manufactured on automatic foundry lines. Due to low level of automation and huge work intensity at this stage of the process, a model area was established which underwent reorganization in accordance with the assumptions of the World Class Manufacturing (WCM). An analysis of work intensity was carried out and the costs were divided in order to identify operations with no value added, particularly at individual manufacturing departments. Also an analysis of ergonomics at work stations was carried out to eliminate activities that are uncomfortable and dangerous to the workers' health. Several solutions were proposed in terms of rationalization of work organization at iron cast after-machining work stations. The proposed solutions were assessed with the use of multi-criteria assessment tools and then the best variant was selected based on the assumed optimization criteria. The summary of the obtained results reflects benefits from implementation of the proposed solutions.

In the paper a method is presented of the best variant selection of a manufacturing process of a rotor to open end spinning machine with use of original optimization proceeding based on adopted criteria, taking into consideration their importance. Unit manufacturing cost and five criteria of manufacturing quality were taken as criteria to the assessment. The assessment criteria resulted from calculations and measurements were normalized. Knowledge of experts was used to determine importance of the criteria taken to the assessment. Each from the experts had built his own importance matrix of the assessment criteria, comparable in pairs, using the Saaty’s method. The weights of individual criteria were determined on the basis of cumulative matrix. In the next stage of the proceeding, normalized decisions were created by raising each assessment to a power equal to corresponding weight. In the last stage of the proceeding, a single optimal ordering comprising the smallest s-th components of the individual decisions d1, d2, …, dm was created. A variant which corresponds to the largest component of the optimal ordering is assumed as the best variant.

Opis:
The paper is to present a multi-criteria approach for sustainability assessment of manufacturing processes, which can be applied to carry out the sustainability assessment of manufacturing processes requiring less detailed data, time, and expert knowledge, but still providing a company-level analysis. The analytical hierarchy process method is used to determine ranking of simple and relevant activity areas for manufacturing processes in terms of sustainability objectives. Analytical technique is also employed to assess the degree of sustainability in manufacturing due to limited information which appear to be a characteristic of the case study presented. One goal of sustainability characterization methodology is to improve the manufacturing sustainability performance. Similar to the baseline scenario, sustainability reevaluation for sustainability improvement is also applied and discuses performance profile at the process level. This approach seems particularly useful when comparing different processes. It makes applicable for various industries and might be a challenge to derive priorities for systematic improvement. The applicability and usability of the proposed assessment method was verified by the case study in company producing heating devices.

Opis:
A review of various bulk metal forming processes that take into account influence of strain path changes on material flow is presented in this paper. Particular attention is put on computer aided design of innovative angular accumulative drawing (AAD) operation. Research in the area of development of metal forming processes taken advantage of strain path phenomena is conducted in many scientific laboratories as the strain patch change effect influences many crucial properties of the deformed material. As a result it provides a possibility of forming materials, which are e.g. difficult to form in a conventional manner. Advantages and limitations of the AAD process are summarized and presented in this work. Difficulties in development of the complex rheological model that takes in to account strain path changes in the deformed material are also presented and discussed.

Opis:
Concurrent execution of work orders in the small and medium size enterprises (SME) imposes a necessity to consider many control problems concerning systems of repetitive concurrent manufacturing processes using common resources in mutual exclusion. In many cases a production system with a given structure of the processes resource requests can be seen as composed of subsystems with n cyclic processes sharing one resource. For given sets of possible values of the processes operation execution times a problem of finding schedules guaranteeing that no process waits for access to the common resources is considered. In particular for the assigned times of the operations execution a subproblem of finding all possible starting times of work orders execution for which waiting-free schedules exist has been formulated as a constraint programming (CP) problem. The starting times derived can be used as an alternative starting times of work orders execution in case of their possible delays. A state space of the problem’s solutions has been reduced using constraints based on the necessary and sufficient conditions for existence of a waiting-free n-process steady-state schedule. An illustrative example of Mozart-based software application to the solution of constraint logic programming problem considered has been presented.
