Modeling the cost of varying surface finish demands during longitudinal turning operations
(2016) In International Journal of Advanced Manufacturing Technology 84(5). p.1103-1114- Abstract
- Tolerances, including geometry, dimension, and
surface roughness, are an important part of production where
the desire to manufacture quality products have to be weighed
against the increase of manufacturing costs. The desired tolerance
will influence the choice of both manufacturing method
and machine tool. Given that machining is an adequate
production method, variation of the required tolerances will
imply a variation of the part cost which needs to be taken into
account during production planning. Thus, the term “tolerance
cost” is introduced. The paper presents a model for evaluating
the tolerance cost in respect to the surface roughness... (More) - Tolerances, including geometry, dimension, and

cost” is introduced. The paper presents a model for evaluating
the tolerance cost in respect to the surface roughness during
longitudinal turning operations, enabling a better comparison
between different production alternatives. Through knowledge
of the required surface roughness, it is possible to estimate
appropriate cutting conditions. Knowledge of the cutting
conditions and the part geometry then makes it possible to
calculate the cycle time, information which in turn may be
used for calculating the corresponding part cost. Through
using experimental data, it is proven that the required surface
roughness has a significant influence on the attained
manufacturing cost. For instance, while longitudinally turning
AISI 4140, it was shown that an improvement of the surface
roughness from Ra=3.2 μm to Ra=1.6 μm will entail an increase
of the part cost by roughly 20 %. Similarly, a decrease
of the required surface quality (larger Ra value) will imply a
significantly reduced part cost. (Less)
