Technological process

Problem statement and the research purpose. The aim of this article is to analyse the wear of drill bits and to identify the elements of the bit that are responsible. Methods. The introduction of computerisation and automation in mechanical engineering has radically changed the approach to drill bit design. The hierarchy of functional elements of the drill bit is represented by a graph in which the drill bit as a product has the following levels: parts, components, zones.

Possibility of modeling statistical characteristics of technological processes at the syages of their design is considered in the paper. Models of technological operations enabling formation of difficult schema of technological processes are examined. Models are oriented to calculation of statistical characteristics with application of characteristic functions.

The paper proposes a new generalized accelerometer model and input parameters identification graph for solving technological processes design automation problem.

In the article the review of the problem of improvement of technology of high pressure hoses cutting on the hand cutting machines is analyzed. Different methods of cutting of high pressure hoses into the billets are overviewed and the quality of edge cuts of hoses is analyzed. The comparison of treatment on automatic cutting machines and on hand cutting machines is carried out. Different experimental techniques of improvement of the quality of edges cutting of high pressure hoses are presented.
