Summary: Flexible technoly has become an unavoidable factor in
modern production systems design. In relation to constructional and
technological characteristics of mechanical products there are plenty of
requirements on flexibility of production systems. The largest processing
posssibilities are offered by the systems wit huniversal flexibility. The
high flexibility level of production system often results with the increase
of the production system price, drop in savings and drop in quality.
Therefore, it is to be recommended the optimal correlation between
flexibility and productivity of the production system.

Summary: One of the basic factors for effective operative process
control is cycle of processing. Precisely determined structure and lasting
of all activies of processing cycle is the fundamental prerequisite for
itďs safe use at operative determining (defining) of work piece course
during a process of production. However, difficulties may appear
considering determining of the same. One of the ways, rather precise and
reliable is determining of the cycle off processing by a graphic method,
based on discreet simulation of the conditions of the production process
course. Researches that were carried on (regarding structure and lasting of
cycle of processing in various models of production systems) prove that the
graphic method is enough precise and reliable.

Summary: Cast manufacture, using that term taking in to account the
production process of the casting plant, is on on-stream production, as it
involves supply, flow and handling of large quantities of material.
Material costs make four fifths of overal costs, therefore, specifying of
the kind and quantity of the material to be used in the production process
is significant. In order to determinate it in the stage of designing of the
technological process, it is necessary to define, on the bases of through
research, adequate methods for determining of raw material quantities to be
processed. As input data in the early stage of technological process
determining net cast mass and casts design are at disposal only. Research
of the set production conditions of the casts will be done in the Casting
plant Torpedo.

Summary: This paper identifies requirements which tool wear and tool
break sensors as a part of flexible manufacturing systems must satisfy for
comercial application. The paper gives a survey of tool wear, tool break
and collision sensors on direct and indirect sensing techniques. All
characteristics of different methods and set-ups are presented. The results
of investigation of tool wear and tool break sensors application based on
the measurement of cutting forces by strain-gage technique are systematised
and analysed. The sensing method is tested by variation of work and tool
material in experimental measurements. Reliability and economy for this
chosen method are estimated.
Keywords: Sensors, tool wear, tool break, flexible manufacturing system, cutting forces

Summary: The concept of the PPS software program aid is based upon
adequate data-basis, numerical data processing and interactive activity of
the planner, allows a quick, efficient and scientifically based elaboration
of manufacturing system project concept. A developed program comprises:
- the generation of a data-base
- segmenting of a conplex manufacturing system into basic subsystems, based
on suitable grouping of similar workpieces
- dimensioning of the system by capacity
- defining and joing of basic manufacturing system models suitable in the
conceptďs implementation phase, by which the manufacturing equipment group
structure is determinated, mode of manufacturing process control, surface
and price.
The computer aid is developed in the Pascal program language.
