“…Dry Drilling. Previous studies researchers proved by using the fast tool servo cutting tool could tremendously enhanced the drilling process with and under the circumstances that influenced the process of producing burrs in Al 7075 [4]. Drilling was carried out in dry conditions using conventional cutting fluid.…”

This study aimed to determine the effect of drilling parameters on hole cylindricity and surface roughness in drilling applications on aircraft wings. It was determined that increasing feed rate resulted in poor hole cylindricity and surface roughness. The ideal feed rate for better hole cylindricity is 0.230 mm/rev, while the ideal feed rate for better surface roughness is 0.200 mm/rev. Both hole cylindricity and surface roughness have a minimum correlation with each other in producing a good quality of drilled holes.

“…One feature of FTS turning is its high frequency oscillation which leads the potential fatigue issue to be carefully addressed during the design [35], [39]. Herein, the modified Goodman approach using the equivalent stress is employed to evaluate the safety factor S f of the optimized mechanism for its fatigue life characterization.…”

“…To investigate the fatigue behavior, the stress is assumed to be harmonically varied between 0 and σ m . Considering the fatigue stress concentration factor K f = 1.4, ultimate strength σ u = 1274 MPa, and endurance limit σ e =700 MPa for the steel [39], the safety factor S f is determined by [21]…”

This paper reports on the mechanism design, dimension optimization, closed-loop control, and practical application of a piezoelectrically actuated fast tool servo (FTS) for the diamond turning of micro-structured surfaces. With the mechanism, a finite element based analytical model is developed to theoretically relate the working performance with its structural dimensions. Considering its application for micro/nanocutting, the structural dimensions of the mechanism are deliberately determined through evolutionarily optimizing a comprehensive objective. To ultra-finely track the cutting trajectory with a high bandwidth, a PID controller together with the dynamics inversion based feedforward compensation is optimally designed with assistance of the Nyquist diagram, and a disturbance observer is further employed to compensate for the inherent hysteresis nonlinearity as well as external cutting force disturbances. Both open-loop and closed-loop experimental tests on the prototype suggest that a stroke of 15 µm and a closed-loop bandwidth of 1730 Hz are achieved. Taking advantage of the newly developed FTS, two typical micro-structured surfaces are ultra-precisely turned, well demonstrating the effectiveness of the FTS.

“…The FTS system normally includes a piezoelectric (or voice coils) actuator, flexure hinges, and positioning feedback sensor as illustrated in Figure 14 [23]. The piezoelectric actuator is a critical component in the FTS system and designed to perform precision positioning of the cutting tool during short stroke turning operations.…”

Smart machining has tremendous potential and is becoming one of new generation high value precision manufacturing technologies in line with the advance of Industry 4.0 concepts. This paper presents some innovative design concepts and, in particular, the development of four types of smart cutting tools, including a force-based smart cutting tool, a temperature-based internally-cooled cutting tool, a fast tool servo (FTS) and smart collets for ultraprecision and micro manufacturing purposes. Implementation and application perspectives of these smart cutting tools are explored and discussed particularly for smart machining against a number of industrial application requirements. They are contamination-free machining, machining of tool-wear-prone Si-based infra-red devices and medical applications, high speed micro milling and micro drilling, etc. Furthermore, implementation techniques are presented focusing on: (a) plug-and-produce design principle and the associated smart control algorithms, (b) piezoelectric film and surface acoustic wave transducers to measure cutting forces in process, (c) critical cutting temperature control in real-time machining, (d) inprocess calibration through machining trials, (e) FE-based design and analysis of smart cutting tools, and (f) application exemplars on adaptive smart machining.
