| Summary: | Tool wear prediction plays a significant role in machining industry for proper planning and control
machining parameters and optimization of cutting conditions. This paper aims to investigate the effect of
tool path strategies that are contour-in and zigzag tool path strategies applied on tool wear during pocket
milling process. The experiments were carried out on CNC vertical machining centre by involving PVD
coated carbide inserts. Cutting speed, feed rate and depth of cut were set to vary. In an experiment with
three factors at three levels, Response Surface Method (RSM) design of experiment with a standard called
Central Composite Design (CCD) was employed. Results obtained indicate that tool wear increases
significantly at higher range of feed per tooth compared to cutting speed and depth of cut. This result of
this experimental work is then proven statistically by developing empirical model. The prediction model for
the response variable of tool wear for contour-in strategy developed in this research shows a good
agreement with experimental work. |
