Przekształcanie cech konstrukcyjnych w cechy technologiczne wymaga wielu powtarzających się rutynowych etapów i czynności, dlatego proces ten - w obrębie określonego typoszeregu - jest podatny na algorytmizację. W artykule podstawowymi narzędziami tworzenia typoszeregów technologii są: - agregacja wiedzy z zakresu konstrukcji i technologii, - zastosowanie metod: teorii podobieństwa technologicznego, algorytmicznej, CAM, - tworzenie baz danych składników dokumentacji technologicznej.

The result of this paper is verification of established model of relation between constructional features (Ck) and technological features (Ct), what was verified on the example of hydraulic servo-motors manufacturing technology. Working on defined reports between construction and technology the row of applications and computational programmes were elaborated. Visual BASIC programming language as well as AutoLISP used in AutoCAD programme were applied in preparing computational programmes. Access and I-DEAS programmes were applied to create the databases of tolls and instrumentations.The basic tool of the series of types of technologies creating (Ten) on the basis of series of types of constructions is creation standard technological structure [3, 5] theory of technological similarity and algorithmic method.

W pracy przedstawiono metodologiczne podejście do tworzenia typoszeregów technologii z zastosowaniem teorii podobieństwa technologicznego. Związane jest to z przekształcaniem cech technologii wzorcowej zgodnie z wyznaczonymi liczbami podobieństwa technologicznego. Liczby te wynikają z rozpatrywanych stanów technologicznych dotyczących mocy skrawania, siły skrawania i objętościowej wydajności obróbki.

The theory of technological similarity is applied for elements characterized by constant constructional form and variational values of dimensions. Technological working plan is created by advanced graphic programs according to traditional methods. Standard structure is used to generate further technological structures by modification of chosen parameters. The selection and transformation of parameters is realized after having defined the system of relations and the system of connections and transformations between individual features. It is important that this method is to be applied to create of technological documentation for series of types of elements.

Purpose: The water and electricity (etc.) supply is the main problem that big agglomerations meet, therefore the non-excavation works are developed in areas of high buildings density. Design/methodology/approach: There are many construction solutions of erosion machines that has already been verified in real tests, but the current goal is to develop non – excavation robotized machine. Erosion machines with main dimensions of the tunnels which are: 1600, 2000, 2500, 3150 are design with use of the computer aided methods. Findings: The result is a modeled in I-DEAS advanced graphical program series of types of the erosion machines with two main designs. The assembly models were analyzed: by system analyze (work simulation of the assembly), by strength analyze (Finite element method) and saved in 2D drawings. Research limitations/implications: The practical methodology verification of creating the systematic part family was based on the designed erosion machines series of types. There were developed: the algorithmic selection methods of quantitative construction attributes, the construction similarity method of the erosion machines, variant analyzes in the I-DEAS advanced graphical program, program and relational parameterization [3,7,11]. There will be created manufacturing process of the parts, which allows to verify the technology on the CNC machines. Practical implications: The designed models will be modified and the construction will be consulted with manufacturers and erosion machine users like: OHL ZS a.s. from Brna, Tauber Rohrbau GmbH & Co.KG from Minster. The companies’ acceptance will result in practical verification by JUMARPOL company. Originality/value: The main achievement is the design of a robotized erosion machine to non – excavation works. The designing process was supported by computer aided methods invented on Silesian University of Technology in the I-DEAS advanced graphics program.

Purpose: The main reason to commence research concerning new methods of transformation technology into structure was introduced in the process of creating ordered technologies on the basis of series of structure. The worked out datum for these methods is as elaborated ordered families of structure in the form of series of types or modular series of elements structure. Design/methodology/approach: This paper shows algorithmic understanding to get input data in the process of technology creation based on data of structure. Basic tool to realize data selection for the process of manufacture is the theory of technological similarity, algorithmic method and use of advanced graphic programme. Findings: The basic result of the analyzed problem is to realize relations between structure and technology for specified series of machine engines elements types. Moreover, the theory of technological similarity with its essential constituents which determine input date for selection processes algorythmisation of technological features on the basis of constructional features was introduced. Research limitations/implications: Analyzed methods develop algorythmisation of designing environment and support integration with the process preparing production. Further analyses will be carried out on in order to specify the theory of technological similarity in new forms of computer-aided (relational databases, theory of automatic classification). Practical implications: Described methods were developed based on practical examples of the technological module systems creation for hydraulic cylinders used in mining, slag cars used in metallurgy and series of gears types. The represented methods are applied to the unit’s types of hydraulic servo-motors used in mining. Originality/value: Method of the technological similarity, the algorithmic method and CAM method are the basis for selection of technological features in the process, which creates the as ordered technology families (types and module systems of constructions). This method is characterized by a possibility to shorten time related to production preparation and series production increase.

Purpose: Theory of construction similarity has its roots in the theory of physical similarity. The model in the theory of construction similarity is a model construction. Model in the theory of similarity of construction and technology is construction and technology standard. Design/methodology/approach: The fundamental aim of the work is the selection of design features in particular type sizes of series of types that allows obtaining physical, stereomechanical and simple states that are identical as in the model construction. The basic form of the record of series of construction types is program and relation parameterization. Features are determined for the items stored in the form of series of construction and technology types. Research limitations/implications: Analysed methods develop algorithmisation of engineers and technologists environment and support integration with the process of preparation the production. Practical implications: Described methods were being developed on practical examples of creating the series of types of hydraulic cylinders used in mining. Originality/value: Method of the constructional similarity, technological similarity presented in the paper are basis of selection of design features in the process of series of types and module systems of constructions and technology creating. All of these methods support intensive development of the types of technical features and affect on their competitive on the ready market.
