Drilling is a highly complex machining process coupled with thermo-mechanical effect. Both the rapid plastic deformation of the workpiece and the friction along the drill-chip interface can contribute to localized heating and increasing temperature in the workpiece and tool. The cutting temperature at the tool-chip interface plays an important role in determining the tool thermal wear. This in turn affects the dimensional accuracy of the workpiece and the tool life of drill. A new embedded heat pipe technology has been proven to be able to effectively not only remove the heat generated at the tool-chip interface in drilling, but also minimize pollution and contamination of the environment caused by cutting fluids. Less tool wear can then be achieved, thus prolonging the tool life. 3D Finite Element method using COSMOS/works is employed to study coupled effects of thermal, structural static and dynamic analyses in a drilling process to check the feasibility and effectiveness of the heat pipe drill. Four different cases, solid drill without coolant, solid drill with coolant, heat pipe drill, and heat pipe drill with coolant, are explored, respectively. The results from this study can be used to define geometric parameters for optimal designs.

ABSTRACTIn forming procedure of the micro grooves in the flat micro-groove heat pipe, the tie rod is often observed to be broken and the multi-tooth cutter is damaged due to the sharp increase of the ploughing-pulling pressure. This paper theoretically analyzes the factors affecting the capillary heat transferring limit of the micro-groove heat pipe, and simulates the machining process using finite element to acquire the best processing parameters: the squeeze angle is 120°, the drawing depth is 0.25mm, and the ploughing-pulling velocity is 100mm/s. Then these parameters are verified by real manufacturing experiments. The experimental results show that the ploughing-pulling pressure of the micro-groove forming process is close to the strength limit of the rod or multi-tooth cutter, and the process makes little swarf during work. Thus, only using the appropriate machine tool parameters, forming parameters and forming methods can make the wicking structure of flat micro-groove micro-heat pipe with the best heat transferring performance.

Heat Transfer Theory

The cutting temperature is a key factor which directly affects thermal distortion, the machined part’s dimensional accuracy, as well as the tool wear in machining process. Aiming to effectively remove the cutting heat yields in machining process, the cutting tool with heat pipe cooling has been developed in recent years. This research focuses on developing a clear understanding of the temperature distribution in end mill embedded with heat pipe. Mathematical model is developed based on the heat transfer theory and the metal-cutting theory. 3-D finite element models are set up. The thermal boundary conditions are properly set, and contrasts of the temperature field in end mill with and without embedded heat pipes by numerical simulations are given.

Tool materials used in ultramicrotomy are glass, developed by Latta and Hartmann (1) and diamond, introduced by Fernandez-Moran (2). While diamonds produce more good sections per knife edge than glass, they are expensive; require careful mounting and handling; and are time consuming to clean before and after usage, purchase from vendors (3-6 months waiting time), and regrind. Glass offers an easily accessible, inexpensive material ($0.04 per knife) with very high compressive strength (3) that can be employed in microtomy of metals (4) as well as biological materials. When the orthogonal machining process is being studied, glass offers additional advantages. Sections of metal or plastic can be dried down on the rake face, coated with Au-Pd, and examined directly in the SEM with no additional handling (5). Figure 1 shows aluminum chips microtomed with a 75° glass knife at a cutting speed of 1 mm/sec with a depth of cut of 1000 Å lying on the rake face of the knife.
