This research work presents the results of the monitoring on a robotic cell operation for welding the bogie frame on a freight wagon for two months. The structure of the robotic welding cell is revealed and a register of the occurred failures was formed. A statistical processing of the received information has been made and an analytical expression about the trouble-free operation has been determined. Recommendations for increasing trouble-free operation are suggested.

This paper presents an option of formalizing input data in automated design processes for machining. A tabular data model required by the technology technician is designed to develop products for the machining process, namely a workpiece. A script-based approach of human-computer dialogue in the setup of structural and technology parameters of a workpiece is adopted as well as particular algorithms to be submitted into the system.

The article studies the prerequisites for the introduction of process innovations at ZMM Nova Zagora JSC. The main principles of an original approach for decreasing the degree of discrete manufacturing by introducing an innovative technological process for mechanical machining of tooth gears are expounded. The results of its introduction in the gear grinding workshop are presented.

The manufacturing programme, production conditions and applied technologies for the mechanical treatment of gears in company “ZMM Nova Zagora” Ltd. are analyzed in this article. The basic formulations of an innovative technological process for grinding of gears are presented. The awaited results of the initiation of the worked-out innovative technological process are exposed.
