Opis:
Constantly improving, which is one of the principles of quality management is the base for good understanding, behaviour of individual processes, investigating variability and impact on its the process. The aim of every business is to increase profits. Reducing the cost of tools can also contribute to this. Utilising the DOE method to reduce the durability of removable cutting plate, as describe the article, is one of way, how to apply this method in practice. The DOE method enables find factors that are the most relevant to the production process and determine their best values. Using this method, you can set the selected inputs so that, the process achieves the desired results with maximum stability and resilience. The article contains a brief overview of Minitab software by which the collected process data was analysed. The core of the article describes how to solve the problem using the singular phases of the DMAIC cycle. Each of these phases has its own specific aim, which logically defines what activities each step is aimed at. DMAIC is extended variant of the process improvement model based at the Deming circle PDCA. Six sigma methodology is used as a standard procedure for project planning and realisation. At the end of an article is described that by increase durability of removable cutting plate the problems found in the analysis of the current condition that have been validated by a case study in the company have been eliminated.

The investigation ofthe Low Temperature Co-fired Ceramic (L TCC) via filling process quality is presented in this paper. The goal of this paper was to propose and to validate a way of the verification whether the L TCC fabrication was conducted correctly. The work presents an application of the Design of the Experiment (DoE) methodology in such validation and discusses usefulness and drawbacks of the chosen solution. The optimized technology of via filling will be applied in the fabrication of tactile displays for blind people.

Opis:
Many manufacturing systems must operate under resource constraints. Simulation can help to improve the operation of such manufacturing systems. This paper presents a practical approach how to conduct a simulation project. A Flexible Manufacturing System (FMS) was chosen for the simulation. The targets for FMS improvement were given. A set of measures was proposed to meet the given targets. Design of Experiments (DoE) was used to minimise the number of simulation experiments. There were simulated and evaluated various measures and control strategies and their influence on the FMS characteristics. Rough cost analysis of each simulated variant was done. Future research targets are presented.

Opis:
Vibratory peening is a mechanical surface treatment process to improve both the fatigue life and smooth surface finish of metallic components in a single operation. Almen intensity is a significant parameter to relate the compressive residual stresses induced by the peening processes. In this study, the design of experiments (DOE) was used to investigate the effect of seven vibratory peening process parameters on Almen intensity. A specific vibratory peening machine, with the tub vibrating in a vertical pattern and resting on airbags, was built. Two empirical linear models were fitted. First, a screening model with primary effects showed that the media mass, airbag pressure, specimen longitudinal position, and lubrication rate have minor influence on Almen intensity. Secondly, a definitive model showed that high eccentricity, high frequency, and deep specimen immersion are required to reach high Almen intensities. The complex interactions between eccentricity, immersion depth, and frequency are described.

Opis:
This paper presents a multi-objective extended optimization methodology applied in the machining of a randomly oriented GFRP rod. Design of Experiment (DOE) has been selected based on a L9 orthogonal array design with varying process control parameters like: spindle speed, feed rate and depth of cut. Multiple surface roughness parameters of the machined FRP product along with the Material Removal Rate (MRR) of the machining process have been optimized simultaneously. The Fuzzy Inference System (FIS) has been proposed for providing feasible means for the meaningful aggregation of multiple objective unctions into an equivalent single performance index (MPCI). This Multi-Performance Characteristic Index (MPCI) has been optimized using the Taguchi method. The approach adapted here is capable of overcoming limitations/assumptions of existing optimization methodologies available in the literature.

Opis:
The present study explores the influence of variables like particle size of coal, load, speed and sliding distance on weight loss in manganese-steel (Mn-steel). The observations are made using pin-on-disc apparatus. Specimen prepared from Mn-steel used for the wear test. The size and shape of specimen is in accordance with ASTM G99 standard. From design of experiment (DOE) procedure the variables load were altered to assess the weight loss in material. It is observed that with the increase in particle size and load, the weight loss increases when other variables are constant. Mn-steel shows decrease in weight loss at higher load due to property of dipole interaction and stacking fault energy (SFE). Decrease in weight loss at higher load results in transition in wear mechanism from scratch to groove formation as observed under field emission scanning electron microscope (FESEM).

Opis:
The aim of this paper is to present methods of digitally synthesising the sound generated by vibroacoustic systems with distributed parameters. A general algorithm was developed to synthesise the sounds of selected musical instruments with an axisymmetrical shape and impact excitation, i.e., Tibetan bowls and bells. A coupled mechanical-acoustic field described by partial differential equations was discretized by using the Finite Element Method (FEM) implemented in the ANSYS package. The presented synthesis method is original due to the fact that the determination of the system response in the time domain to the pulse (impact) excitation is based on the numerical calculation of the convolution of the forcing function and impulse response of the system. This was calculated as an inverse Fourier transform of the system’s spectral transfer function. The synthesiser allows for obtaining a sound signal with the assumed, expected parameters by tuning the resonance frequencies which exist in the spectrum of the generated sound. This is accomplished, basing on the Design of Experiment (DOE) theory, by creating a meta-model which contains information on its response surfaces regarding the influence of the design parameters. The synthesis resulted in a sound pressure signal in selected points in space surrounding the instrument which is consistent with the signal generated by the actual instruments, and the results obtained can improve them.

This paper describes the p-diagram (parameter-diagram) and its application in planning a DoE (Design of Experiments). A case study describing an actual problem from industry is presented where the planning phase started to go wrong as difficulties in selecting the right variables for the DoE were discovered. Furthermore, running these experiments became prohibitively expensive, due to the large number of such experiments that would be needed, and though the exploitation of a p-diagram it was then possible to come up with a feasible DoE.
