In the present study, high-speed and ultra-high-speed face milling of AISI H13 steel (4647 HRC) was conducted in order to acquire a thorough understanding of the Al2O3-based micro-nanocomopsite ceramic cutting tool AWT10 wear mechanisms in high-speed hard milling. For different cutting speeds, the typical tool wear mechanisms is analyzed and compared. The analysis of the tool wear show that abrasive wear, adhesive wear, spalling and breakage are the primary wear mechanisms of AWT10 when cutting speed reaches 3000m/min. Micro-nanocomposite ceramic material AWT10 has favorable property of shock resistance. Improved cutting speed is in favor of cutting force reduction.

Cutting Model

Cutting tool temperature is the main factor that directly affects tool wear and tool life. In this paper we developed temperature model of tool insert during slot milling process, constructed by a combination of cutting time model and non-cutting model. A set of experiments are designed and carried out to obtain cutting induced temperatures at different cutting speeds during slot milling of AISI H13 steel. Experiments results indicate that tool insert temperature increases first and then decreases as the cutting speed grows, and a critical cutting speed for the tool insert temperature exists during slot milling of AISI H13 steel. Some possible reasons for the drop of tool insert temperature are proposed and discussed, and they are decreased heat flux into tool insert and increased heat convection coefficient.

For the purpose of acquiring thorough understanding of the characteristics of cutting force in high and ultra-high-speed face milling of hardened steel, experimental investigations on face milling of AISI H13 steel (46-47 HRC) are conducted in the present study. The cutting speed of 1400 m/min, at which relatively low cutting force and relatively low surface roughness can be obtained at the same time, is considered as a critical value for both mechanical load and surface finish. The Taguchi method is applied to investigate the effects of cutting parameters on cutting force in different speed ranges (below and above 1400 m/min). In different speed ranges, the contribution order of the cutting parameters for the resultant cutting force is the same, namely axial depth of cut, cutting speed and feed per tooth. However, the contributions of cutting speed and feed per tooth increase substantially as the cutting speed surpasses 1400 m/min. Within the range of cutting parameters used in the present study, the optimum cutting conditions for the cutting force are cutting speed 200 m/min, feed per tooth 0.02 mm/tooth and axial depth of cut 0.1 mm.

Tool Wear Mechanisms

An experimental investigation of wear mechanisms in high-speed turning of superalloy GH2132 with Al2O3-based ceramic was conducted under dry cutting condition. The tool wear mechanisms were characterized by observation of tool wear morphology using scanning electron microscopy (SEM) and detection of the element distribution of the worn tool surface utilizing energy dispersive X-ray spectroscopy (EDS). The results of turning experiments indicated that the major wear mechanisms of the ceramic cutting tool were synergistic interaction between abrasive wear and adhesive wear, and meanwhile the micro-chipping was also observed. It is also shown that cutting distance of the Al2O3-TiC ceramic cutting tool at the speed of 420 m/min was higher than that of the speed of 360 m/min and 540 m/min.

In this paper, the oxide nanometer composite cutting performance of ceramic tools cutting cast iron were studied. And the tool failure modes were mainly analyzed. Through the study found that, with the increase of tool wear with cutting speed, failure forms mainly adhesion wear. When the cutting speed is low, the knife before the crater wear become the main form of ceramic cutting tool wear, boundary wear and the surface of the knife after wear is also very serious. And in the process of cutting, the collapse edge can also occur now; With the increase of cutting speed, collapse become the main failure forms of cutter blade.

Wear Monitoring

The wear of TiCN coating carbide cutting tools (Sandvik® Grade 1010 and 4220) in different hard-milling machining conditions was monitored, analyzed, and discussed for AISI H13 steel. This material is commonly used in the forge industry in order to optimize the manufacturing process according to a qualimetry/cost compromise criterion. AISI H13 steel generally is used in modern production for high wear-resistant dies and molds. One of the most basic and primary geometric shapes in the manufacture of molds and die cavities is the geometry known as "inclined plane." Experimental investigations were carried out on a "mold model" design with the aim of analyzing and optimizing the principal manufacturing conditions. The tests are dependent on manufacturing factors, particularly their impactin a complex tribological process. Five clearly defined different surfaces of the hardened AISI H13 steel model mold, with appropriate geometries were studied; i) vertical downward; ii) curved downward; iii) horizontal; iv) curved upward; and v) vertical upward.The analysis of cutting tool wear during this process was based on computerized measurements of visually observable wear and power consumption. Morphological investigations of the surface topography for the cutting tool, as well as of the work-piece surfaces, were systematically carried out. Moreover, the interactions with simultaneously measured energy consumption during the process are also explicated in the present study and therefore tentative methods to optimize hard-milling machining are offered.
