RESEARCH CONCERNING THE FORMING FORCES AT COLD TOOTHING BY INTERMITTENT BLOW

Among the processing methods by cold flow, toothing by intermittent blow is one of the most widespread. The size of the forming force is the most important criterion in establishing the technological system for the processing by cold volume flow. The knowledge of its values enables the choice of the smallest size order of the machine tools, respectively of the special device. The paper presents aspects of the experimental research on the process of cold toothing by intermittent blow. There are presented the expressions of consecutive forming forces (pressures) using mathematical statistics and the conclusions which highlight the fact that the forming forces at cold toothing by intermittent blow depend on the nature of the material to be machined and the toothing process parameters, the feed travel of the semiproduct) and the toothing speed (V-d).
