摘要

The knowledge of this research is established on the newly proposed internally cooled tool having the cooling channel make inside the insert. In the high pressure coolant turning, the differential pressure caused by the hydraulic pressure at the flank wedge and atmosphere pressure at each end of cooling channel is able to advance the cutting heat dissipation by enhanced flow. This paper focus on the relation between tool wear and cutting fluid flows produced by cooling channels having different angular positions. Computational fluid dynamics analysis based on the three-dimension turbulent model was used to simulate the flow streamline to clarify the cooling ability, followed by the experimental verification in the high pressure jet assistance turning of Inconel 718. As a result, applying cooling channel was proved can prolong tool life by about 40 most and received an advanced surface quality even the critical pressure was reached. The cooling channel made near to the cutting notch and major flank significantly suppressed the notch wear and flank wear, respectively.
