THE ANALYZE OF FRICTION CONDITIONS ON A RAKE FACE WHEN FINISH TURNING ON THE BASE OF CHIP THICKNESS CHANGES
Journal Title: Tribologia - Year 2010, Vol 232, Issue 4
Abstract
In the paper, the results of the analysis of theoretical equations to calculate middle coefficients of friction on a tool rake face during finish cutting are described. Equations viewed were compared with experimental results. The base magnitude that characterises friction conditions into the cutting zone is uncut chip thickness. Using its values, one may calculate shear angles and friction angles on tool rake face. The proposed method was used to analyse the process of steels 45, R35, 40H, NC6, duralumin PA6 and molybdenum turning with different conditions. Depending on chemical composition and physical-mechanical properties of material machined, using antiwear coatings and cooling conditions, middle coefficients of friction on tool rake face may be decreased from 10 to 20%.<br/><br/>
