“…The minimum surface roughness is achieved near the minimum UCT which is estimated to be 0:2 À 0:3 ð Þ r b . The deviation from the theoretical value has also been investigated by Childs et al [154,155]. They thought the feature of the cutting tool that determined the machined surface roughness changed from the tool nose radius to the tool edge radius, as the feed was reduced in turning process.…”

Micro-and nano-machining technology has been applied in industry to generate high-precision parts with micro/nanometric accuracy or feature size in the recent decades. Cutting is one of the most powerful manufacturing processes, and the material removal mechanism is urgently demanded by the industry to understand and improve the micro/nano-machining process efficiently at a low cost. This paper presents the recent advances in cutting mechanism and its applicability for predicting the surface generation and chip formation, especially when material is removed in micro-and nanoscale. In addition to the industry-concerned performance parameters, fundamental physical parameters such as stresses, strains, temperatures, phase transformation, minimum uncut chip thickness and size effects are discussed in this paper for the indepth understanding of the micro/nano-cutting process.

“…The accurate tool path generated by the stable and rigid slides 3 and spindle of the diamond turning machine as well as the good cutting performance of the single point diamond cutting tool makes the machined surface to have a good form accuracy and a high surface quality. [4][5][6][7] The fast tool servo system has been developed for improving the bandwidth of a diamond turning machine so that the micro-structured surfaces can be generated. 8 A fast tool servo is generally composed of an actuator for driving the cutting tool, a capacitive sensor for measuring the actual depth of cut and a controller for feedback control of the tool displacement.…”

This paper presents the experimental results of investigating the performances of an air-bearing displacement sensor for surface form measurement of micro-structures, such as micro-lenses, on an ultra-precision machine tool. The sensor consists of a stylus for contacting the surface, a shaft for mounting the stylus, an air-bearing for suspending the shaft and a blade spring for applying the measuring force against the surface. At first, experiments were conducted on a vibration isolated table to identify the basic performance of the sensor for displacement measurement. Then, the sensor was mounted on a diamond turning machine for evaluating the performance of the sensor for on-machine surface form measurement of micro-lenses. A roll workpiece, on which a micro-lens array was fabricated by using a fast tool servo on the diamond turning machine, was employed as the specimen for the on-machine experiment of surface profile measurement.

“…Liu [11] reported that the micro cutting process is affected by two mechanisms, chip removal and plowing due to the minimum chip thickness effect. The surface quality is affected by a variety of factors including machining parameters, tool geometric, and workpiece material [12][13][14]. It is found that in micro cutting, the surface roughness at first decreases with feed, reaches a minimum, and then tends to increase with further reduction in feed.…”

Since the uncut chip thickness is comparable to the cutting edge radius, in fact, micro cutting is a negative rake angle cutting process. The minimum chip thickness has great effect on the cutting process. This paper presents an experimental investigation of specific cutting energy and surface quality based on the negative effective rake angle in micro turning. A new model is developed to calculate the negative effective rake angle in micro cutting. The effective rake angle is found to be more negative with the decreasing ratio of uncut chip thickness to cutting edge radius. The minimum chip thickness is calculated to be about 0.2-0.3 times of cutting edge radius based on the critical negative rake angle. The turn point of the nonlinear increase of specific cutting energy is observed to be at the critical negative rake angle. The minimum surface roughness also is found to be achieved near the critical negative rake angle.
