Abstract
In integrated manufacturing systems, a very important issue is the problem of ensuring the reliability of cutting tools, in particular high-speed steel broaches. To ensure the required quality of machining, the tool should be changed at specified intervals. Determining the tool replacement period and forecasting the tool's working ability is a difficult and complex issue due to the dispersion of the properties of the tool material and the workpiece. The paper presents the results of research on the dynamics of wear of HS 18-0-1 steel broaches, conducted under production conditions. Based on the analysis of the obtained results, it was shown that the scatter curves of the wear broach teeth VBalong its length and the standard deviation are in the form of a bathtub curve, which indicates uneven work of the broach teeth. In turn the teeth wear variance coefficient can be used to assess the effectiveness of its work. The research also shows that coated broaches are characterized by greater teeth wear stability and double reliable operation.
