2020, Journal of Materials Processing TechnologyCitation Excerpt :The advantages of HPC mentioned above mainly derive from its ability of delivering high-pressure coolant to the contact regions between tool and chip/workpiece, which gives HPC outstanding cooling and lubrication ability. Wertheim et al. (1992) applied high pressrue flow in metal cutting processes and claimed that HPC can get good access to cutting heat sources by seeping into cutting regions. Sharma et al. (2009) reviewed the role of HPC in turning and pointed out that HPC can penetrate the tool/workpiece interface to create hydraulic wedge, resulting in alteration of chip flow conditions and reduction of tool-chip contact length.
Novel cutting inserts with multi-channel irrigation at the chip-tool interface: Modelling, design and experiments
2020, CIRP AnnalsCitation Excerpt :With more advanced materials, e.g. superalloys, applied in various high-value industries, the cutting tool performance is facing critical challenges due to the complex properties of those materials such as high strength at high temperature, which thereby lead to severe thermomechanical loads and result in accelerated tool wear [1–4]. High pressure coolant is of advantage to reduce the cutting temperature and enhance chip control in superalloys machining to enable adequate surface integrity and cutting tool performance [5–7]. However, the conventional solutions (Fig. 1a) for high-pressure cutting fluid delivery rely on “macro-nozzles” (i.e. dimensions comparable with those of the cutting tools) positioned outside the chip-tool interface that miss to deliver the coolant at the critical tool-chip/workpiece contact zones efficiently [6,8].
Chip control in turning with synchronization of spindle rotation and feed motion vibration
2018, Precision EngineeringCitation Excerpt :However, turning often generates long chips during machining because the tool surface is continuously in contact with the workpiece during the cutting process. For this reason, it is difficult to supply coolant to the interface between the chip and the tool even if a large amount of coolant is used [1]. Therefore, insufficient lubricity of the tool surface can cause adhesion to the tool.
