Special Issue Information

Dear Colleagues,

Recently, industries and manufacturers have been increasingly attracted to the production of micro- and nanoscale components because of their many advantages, such as lower production energy, minimal material waste, and corresponding stability issues, as well as their suitability for smart systems. However, selecting an appropriate manufacturing method for these purposes is always challenging because of size limitations and strict tolerances. Machining processes are effective and cost-effective production methods used for the production of miniature components because of their high production rate and appropriate accuracy. However, the advancement of these methods for massive productions with reliable accuracy still merits further comprehensive research in wide relevant aspects.

Accordingly, we are organizing a Special Issue entitled “Micro/Nano Machining Technology and Applications” to address the previously mentioned challenges. The topics covered in this SI can be summarized as follows:

  • Micro-machining based on the mechanical material removal process;
  • Non-conventional micromachining;
  • Micro-machining modeling using theoretical and numerical simulation;
  • Geometrical and dimensional tolerances and surface roughness inspection;
  • Process condition monitoring;
  • Micro-cutting tools;
  • Micro-machining for medical devices.

Real-time parametric interpolation plays a crucial role in achieving high-speed and high-precision multi-axis CNC machining. In the interpolation cycle, the position of the next interpolation point is required to be calculated in real-time to guide the action of the machining process. Due to the existence of the positioning error of the interpolation point, it is extremely difficult to eliminate the feedrate fluctuation, which may lead to dramatic decreases in machining quality and the driving capabilities’ saturation of each axis. A computationally efficient and precise feedrate fluctuation minimization method is proposed for the NURBS tool path interpolation in the CNC milling process. The model for the arc length and curvature, with respect to the parameter of the NURBS tool path, is established to reduce the calculation amount required by interpolation points determination. The deviation between the theoretical and actual interpolation step length is decreased by the proposed arc length compensation method to minimize the feedrate fluctuation. In addition, the interpolation points derived from the arc length compensation process are further corrected by performing the Newton iteration to restrict the feedrate fluctuation within the preset accuracy threshold. The effectiveness and superiorities of the proposed feedrate fluctuation minimization method are verified by simulation and milling experiments. Full article
