Abstract
The attempt of the present study has addressed an area that has been relativelyneglected in the past researches. This area focuses on studying and analysis the effect
of different centered and un-centered workpiece lengths, using turning machine
tailstock, on the products surface roughness, and then collecting data to generate an
experimental charts and equations for the prediction modeling of surface roughness
and increasing productivity for many turned products. These charts and equations
could be serving as a quick indication for manufacturers to avoid pre-chatter conditions
and the trial and error methods, and consequently reduce the required experience in
this field. So, the applicable range of workpiece lengths can be safely extended from
10 mm to 60 mm bars with 10 mm in diameter, and from 10 to 75 mm bars with 20
mm in diameter. This range could be increasing as bar diameter increasing and vise
versa.
