A new method for evaluation nominal coefficient of friction and frictional forces in turning and inserts characterization using cutting forces profiles

This study presents a formulation of the nominal’s coefficient and friction forces generated in machining between workpiece and cutting tool using cutting force profiles. The obtained equations led to the evaluation of coefficient, frictional forces and cutting inserts characterization in terms of better surface finish and lowest frictional forces. | A new method for evaluation nominal coefficient of friction and frictional forces in turning and inserts characterization using cutting forces profiles Engineering Solid Mechanics 4 2016 1-8 Contents lists available at GrowingScience Engineering Solid Mechanics homepage www.GrowingScience.com esm A new method for evaluation nominal coefficient of friction and frictional forces in turning and inserts characterization using cutting forces profiles Hamid Tebassia Mohamed Athmane Yallesea Ikhlas Meddoura a Mechanics and Structures Research Laboratory LMS May 8th 1945 University BP 41030 Algeria ARTICLE INFO ABSTRACT Article history Serviceable engineering components not only rely on their bulk material properties but also on Received 6 April 2015 the design and the characteristics of their surface. These characteristics influence directly the Accepted 19 October 2015 surface quality of the machined products. In terms of surface roughness the influence of the Available online tool material can be also caused by its tribological properties i.e. a contact behavior between 28 October 2015 cutting tool and workpiece. This study presents a formulation of the nominal s coefficient and Keywords Tribology friction forces generated in machining between workpiece and cutting tool using cutting force Coefficient of friction profiles. The obtained equations led to the evaluation of coefficient frictional forces and Normal forces cutting inserts characterization in terms of better surface finish and lowest frictional forces. Frictional forces Indeed results show that the contact between cutting tool and workpiece depends on the Inserts characterization materials cutting tool nature and that the cutting tool type can influences the surface roughness of the machined surface. 2016 Growing Science Ltd.
