Abstract
This paper presents the development of mathematical models for torque and
power in milling 618 stainless steel using coated carbide cutting tools. The
response surface method was used to predict the effect of power and torque in
the end-milling. From the model, the relationship between the manufacturing
process factors, including the cutting speed, feed rate, axial depth and radial
depth with the responses such as torque and power, can be developed. Beside the
relationship, the effect of the factors can be investigated from the equation
developed. It can be seen that the torque increases with a decrease of cutting
speed with an increase of the feed rate, axial depth and radial depth. The
acquired results also show that the power increase with an increase in cutting
speed, feed rate, axial depth and radial depth. It can be found that the second
order is more accurate based on the variance analysis and the predicted value is
closely matched with the experimental result. Third- and fourth-order models are
generated for both responses to investigate the 3- and 4-way interaction between
the factors. The third- and fourth-order models show that 3- and 4-way
interaction was found to be less significant for the variables.
Keywords: torque, power, end-milling, response surface method.
1 Introduction
In this work, experimental results were used for modeling using response surface
roughness methodology (RSM) [1]. The RSM is practical, economical and
relatively easy to use and it has been used by many researchers for modeling
