| Summary: | The increase of consumer needs for quality metal cutting related products (more precise tolerances and better
product surface roughness) has driven the metal cutting industry to continuously improve quality control of
metal cutting processes. Within these metal cutting processes, the end-milling process is one of the most
fundamental metal removal operations used in the manufacturing industry. The aim of the this study is to
develop the surface roughness prediction model for Hastelloy C-22HS with aid of statistical method, using
coated carbide cutting tool under various cutting conditions. This material is superior materials for corrosion
resistance which commonly used underwater applications such as submarine components and etc. This
prediction model was then compared with the results obtained by experimentally. By using Response Surface
Method (RSM) of experiment, first and second order models were developed with 95% confidence level. The
surface roughness was developed in terms of cutting speed, feed rate and axial depth using RSM and design of
experiment. In general, the results obtained from the mathematical model are in good agreement with that
obtained from the experiment data’s. It was found that the feedrate, cutting speed and axial depth played a major
role in determining the surface roughness. On the other hand, the surface roughness increases with a reduction
in cutting speed. |
