Purpose: The paper is focused on the assumptions of the method of discretizing the states of sequential systems for an exemplary robotized metallurgical semi- finished products treatment department. The control of digital equipment is described on the bases of the patterns of control bites sequence configuration. The need for the development of a discretization method stems from difficulties encountered in representing the state of a process of an analogue nature. The crucial barrier is the method of treating the input signal to the visualization system. Design/methodology/approach: The proposed method is based on determining the variables that control the course of visualization in a manner enabling the treatment of all signals as boolean variables. Such approach requires a proper formulation of the input information flux to secure an explicit identification of the states of the served process. Findings: On the grounds of the assumptions a system of visualization is created to attempt the service of a robotized treatment centre. The main emphasis is put on devising an unambiguous way of identifying the states of an industrial robot and its cooperating sensors. Research limitations/implications: The result is the presentation of the combination of control elements in a bite vector used for defining the state of failure or for detecting operational irregularities. Originality/value: The originality of the paper is the approach towards the problem of processes visualization which may be categorized to a group of discrete processes with elements of analogue control data processing.

Purpose: of this paper is present a new approach to modelling and design the low cost mono-block dental implants based on the integration of the computer aided techniques. This approach provides the automation of the design process of the mono-block dental implants. Design/methodology/approach: The approach used to develop the modelling and design of the mono-block dental implants are based on the parametrization of the main geometric features of the implants. This approach allows to generate several designs of the implant with different configurations respect to the dimensions, forms and tolerances. Findings: The findings are focused on two main topics. The first one is the minimization of the manufacturing cost and time based on the manufacture process automation. The second one is the integration, in the same informatics platform, of the design, analysis and manufacturing environment. Research limitations/implications: The implications are focused on the development of a new design of mono-block dental implants. One of the main features of this design is associated to the reduction of the surgical stage and their simplification respect to other commercial implants. Practical implications: The main outcomes and implications of this research is the design of a low cost dental implant. This solution is implemented to assist the social programs of oral health. Originality/value: The originality of this research is the design of a new model of mono-block dental implant. The structure of this implant improves the mechanical properties; reduce the manufacturing cost and the surgical complications.
