Tool wear modes and mechanisms of AISI 1030 steel during intermittent milling were not addressed and
therefore it is substantial to generate machining data for the same. The experimental work is to understand tool wear
modes and patterns of TiN (Titanium Nitride) coated and uncoated cemented carbide inserts during intermittent cut.
Tie bar plates made of AISI 1030 steel were selected for the experiment. Face milling along the bore of the tie bar
plate (where the intermittent cut takes place) was conducted in many trials. Experiments was conducted according
to the selected Taguchi’s L9 Orthogonal array in a Vertical machining centre (VMC – Deckel Maho make), and
finally the results were compared and validated.
