“…Besides the chip-breaker, the macro surface structures shown another function in the previous research. Shu et al [13] manufactured inlet and outlet channels within the tool holder, and then assembled the insert upside down on the tool holder. The channels and grooved chip-breaker made up a sealed flow channel, which functioned as an internal cooling system.…”

In modern tool industry, the design and manufacture of cutting tool surface have been highlighted to fulfill the ever-increasing demands of advanced manufacturing, e.g., lean production, intelligent manufacturing and Industry 4.0. Chip-breaker is a triumph of applying the specific macro structure on rake face, not only contributing to chip controlling, but also being capable to reduce cutting force and tool temperature. In recent decade, surface texturing has been emerged on tool surface, indicating that research focus of surface structures on tools is evolving from macroscale to microscale. The present study reviews functions, optimization and manufacture approaches of different scale structures on cutting tools, aiming at providing a global view of related technologies and revealing the possible developing tendency in this field. This paper could greatly facilitate future research and industrial application of tool surface modification, especially for the integrated application in multi-scale.

“…Previous research showed that the maximum cutting temperature is located at a position that is near the center of the tool-chip contact area. For simplicity, the tool-chip contact face was assumed as a uniform temperature distribution area [14]. There are three different coordinate systems, which are defined as S(XOY), S 1 (…”

Abstract:The cooling system has emerged as an effective way to alleviate the excessive heat generation during dry cutting processes. In this paper, we investigated a novel type of internal cooling system, independent of additional mechanical accessories, as a promising cooling alternative. The proposed system is devised as connected internal fluid channels of a-"V" shape created according to the geometric shape of the tool-holder. Enabling quantitative evaluation of the effectiveness of the proposed system, a new numerical approach is established. Within the approach, heat transfer equations are deduced according to thermodynamics; parameters of the equations are specified via analytical modeling. As a result, cutting temperatures can be estimated with high precision according to the outlet temperature. Moreover, a cutting experiment was carried out to verify the effectiveness of the proposed numerical approach. Tool-chip interface temperatures were measured using an infrared thermal imager. Smooth measurements with suppressed noises are derived based on a new adaptive mean filter originated by empirical mode decomposition (EMD). The experimental results demonstrate the proposed system can reduce the temperature substantially (almost 30% at the measuring point) and the results are highly consistent with those of numerical simulation. The proposed cooling system is a prospective enhancement for development of smart cutting tools.

A thermal model estimating workpiece temperature in orthogonal turn-milling compound machining for the case with noneccentricity between rotation axes of workpiece and tool has been established in this paper. Milling tool and machining history were discretized into infinitesimal elements of equal size to deal with complicated cutter geometry and intermittent cutting procedure. The geometries of milling tool and workpiece were analyzed to calculate the instantaneous chip thickness, axial depth of cut, and angles of cutting entry and exit. Heat source during cutting process was considered as instantane ous moving rectangular heat source and heat conducting function in infinite solid thermal conductivity was developed. Experiments measuring cutting force and workpiece temper ature were launched to test validity of this model and figure out the importance of effects those factors have on workpiece temperature from variance analysis of orthogonal experiment results. Furthermore, simulations to calculate peak temperature of workpiece were carried out by this model with relevant machining parameters and the results matched conclusions from experiment well.
