Effect of tool vibrations on surface roughness during lathe dry turning process

Effects of Cutting Tool Parameters on Vibration

“…They concluded that the feed didn't influence the vibrational signal and had a little effect on surface roughness. Thomas [15] studied the effect of tool vibration on surface roughness during lathe dry turning process on mild carbon steel samples at different levels of speed, feed, depth of cut, tool nose radius, tool length and work piece length. Safeen [16] studied the effect of cutting tool vibration on surface roughness of work piece in dry turning operation .The surface roughness of the work piece is proportional to cutting tool acceleration.…”

Contour finish turning operations with coated grooved tools: Optimization of machining performance

“…This equation works quite well for moderate machining involving medium cutting conditions, but finish turning operations always seem to give much higher measured R a values than the predicted theoretical values by this equation (Jawahir et al, 1992). This is because the real surface roughness can be attributed to the influence of physical and dynamic phenomena such as friction of the cut surface against tool point and vibrations (Thomas et al, 1996). Hence, the database for surface roughness is experimentally created and a cubic spline interpolation method is applied to obtain the surface roughness function.…”

Surface roughness prediction in turning using artificial neural network

“…It has been assumed that one of the major sources which cause visual differences between the theoretical and natural surface roughness is the relatively strong adhesion at the tool-chip interface at the rake surface. Thomas et al [13] studied the effect of tool vibration on surface roughness in dry turning operations. They have performed experiments at different levels of speed, feed, depth of cut, tool nose radius, tool length and work-piece length for the mild carbon steel work-pieces.…”
