This paper presents the application of an experimental method for determining the numerical values of the machinability factors of medium alloy carbon steel in the drilling process. Research conditions are defined, including tools, machine, and machining parameters. The experiment was performed according to a two-factor orthogonal experimental plan, and the values of cutting forces were monitored using a dynamometer through other elements of the information measuring system. Cutting forces were also considered in relation to the drilling depth.

The trend of using micro-parts in modern industry puts new tasks for contemporary production technologies. If these parts are made of difficult-to-machine materials, machining problems become more complicated. On the other hand, the requirements go towards manageable and stable production processes, reduction of the processes number, reduction of the machining cost, using of clean technologies, etc. Use of mechanical solid tools in engineering materials micro-machining, many problems occur, such as: high machined surface roughness of the, tool deflection, intensive tool wear, etc. These problems lead to difficulties in establishing adequate process models, and thus the ability to control of micro-milling process and it’s including in smart processes and smart factory concepts. This paper presents the possibilities of using micro-milling in the difficult-to-process materials machining. The phenomena in micro-cutting are analysed, as well as the output machinability indicators (surface roughness, tool wear, etc.). As a conclusion, guidelines and technological frameworks for the application of micro-milling in practice are given.

A multi-agent Process Planning system for prismatic parts is proposed. This system consists of different basic agents and a negotiation protocol between the agents is described. The individual agents have the ability to communicate with other agents and make different decisions.
