Abstract

This paper deals with the fabrication of micro cylindrical tools and micro flat drills of ultra-fine grain cemented carbides by grinding with ultrasonic vibration. The concept of this grinding is to reduce the grinding forces such that they will not cause any breakage to the micro tools. The grinding operations are performed using the end face of an offset grinding wheel. In grinding with ultrasonic vibration, better results in aspect ratio and tools of smaller diameter than conventional grinding are obtained. Due to the lower tensile strength of carbides, grinding under compressive force has made it possible to grind to a diameter of 11 μm with a length of 160 μm.

    Other examples of miniaturized products are manufacturing methods for micro tools like micro end mills [3], micro drills [6] and micro pencil grinding tools (MPGTs) [7]. A number of processes have been used to manufacture micro tools, including: grinding using thin grinding wheels [3], electrical discharge machining (EDM) [8] and laser processing [9]. In turn, these micro tools can be used to produce micro components and micro textured surfaces [3].

    Increasing the rotational speed of the tool increases the material removal rate and decreases the rate of tool wear [115,202]. The applications of micro RUM include not only drilling and grooving but also the fabrication of micro carbide tools (11 μm in the diameter and 160 μm in length) [185] and a carbide rod with aspect ratio 310:1 and diameter 42 μm [260]. The fabrication of thin, tens of micrometre thick SiC diaphragms for pressure sensors using ultrasonic vibration mill grinding is a novel application [141].

    Due to the problems arising from mechanical contact during micro tool fabrication, the major concern is to reduce machining forces [160]. In an attempt to reduce grinding forces Onikura et al. [160] efficiently used ultrasonic vibration grinding (75 kHz-0.5 μm), to fabricate micro cutting tools with diameters less than 100 μm and aspect ratios in the range of 3 to 18. They came into a conclusion that by applying ultrasonic vibrations, it is possible to achieve a 10–20% reduction in the diameter of micro tools and to increase aspect ratio about 50%.
