Tooling materials science| Summary: | The paper analyzes the influence of the injection of the regimes of cutting and wear of the cut for the correction of defects in the chipboard opening when cutting with a Forstner drill. In the course of the study, the main stages of the formation of the hole in chipboard were determined, as well as the value of the axial force P0 at all defined stages of processing. To assess the quality of the hole, the dimensionless Fed layering criterion was determined. It was established that the wear of the drill plates leads to an increase in the average P0 and the maximum P0 max of the axial cutting force. |
