Special Issue Information

Dear Colleagues,

“High-Speed Machining” broadly relates to advanced technologies and systems that allow materials to be processed at very high speeds to achieve significant improvement in both productivity and quality at equal or lower cost. This essentially includes dimensional and shape accuracy, as well as surface topography and surface integrity with regard to the material to be processed. Initially the focus of the majority of high-speed machining research has been directed towards improving material removal rates. Tool materials capable of withstanding high cutting speeds have become available and the focus of research has now shifted to maximizing the cutting performance of the machine tool. Measurements of cutting performance, chatter avoidance, structural design, tool retention, and axis control have become important research topics over the years. In addition to a focus on successful and critical applications of high speed machining, this Special Issue of JMMP, seeks to publish original and review articles that advance productivity and quality of conventional and non-conventional material processing technologies. The Special Issue intends to publish original research from a broad range of topics and approaches critical to new application areas of high speed machining; machine and component design for reliable implementation of high speed machining; modeling, monitoring, and control of high speed machining processes; integration of high speed machining with new manufacturing paradigms; reliability and cost control of high speed machining.

The topics include, but are not limited to:

  • High Speed Machining of aluminum and other non-ferrous metals
  • High Speed Machining of hardened materials in die/mold manufacturing
  • High Speed Machining of advanced materials, such as composite and ceramics
  • Cutting tools for High Speed Machining
  • Surface engineering for cutting tools in High Speed Machining
  • Tool interface design and automation
  • Machine structure dynamics: stiffness, damping, and vibration
  • Cooling and lubrication strategies, chatter suppression
  • Modeling of High Speed Machining processes
  • Precision and quality control of High Speed Machining
  • Integration with new manufacturing paradigms, such as additive manufacturing
  • CAD/CAM, process planning, and factory layout to take advantages of High Speed Machining
  • Reliability and cost control of High Speed Machining
  • High speed implementation of non-conventional manufacturing processes, such as high-speed laser cutting, water-jet cutting, plasma etching, EDM, etc.

When machining titanium alloy parts, aside from accuracy, the other key concern when evaluating their quality is the integrity of the machined surface. Residual stress can have a significant impact upon this. A certain amount of residual stress can help to strengthen the workpiece, but excessive residual stress can lead to its deformation. In this paper, we report on an experimental study of the surface integrity of titanium alloy after milling with a microtextured ball-end cutter. Tests were conducted to assess the residual stresses on the surface of titanium alloy workpieces according to the direction of feed and milling. The impact of different micro-texture parameters was also assessed; namely, the diameter, depth, spacing and distance from the cutting edge of the individual pits. Range analysis, which is an orthogonal test, was used to analyze the results of the experiments and a prediction model of surface residual stress was established for the milling of titanium alloy with micro-textured ball-end cutters. This model can provide theoretical support for the optimization of the parameters involved in future milling processes. Full article

We provide experimental evidence that the laser beam scanning strategy has a significant influence on material removal rate in the ultrafast laser machining of glass. A comparative study of two laser beam scanning methods, (i) bidirectional sequential scanning method (SM) and (ii) bidirectional interlaced scanning method (IM), is presented for micromachining 1.1-mm-thick borosilicate glass plates (Borofloat® 33). Material removal rate and surface roughness are measured for a range of pulse energies, overlaps, and repetition frequencies. With a pulse overlap of ≤90%, IM can provide double the ablation depth and double the removal rate in comparison to SM, whilst maintaining very similar surface roughness. In both cases, the root-mean-square (RMS) surface roughness (Sq) was in the range of 1 μm to 2.5 μm. For a 95% pulse overlap, the difference was more pronounced, with IM providing up to four times the ablation depth of SM; however, this is at the cost of a significant increase in surface roughness (Sq values >5 μm). The increased ablation depths and removal rates with IM are attributed to a layer-by-layer material removal process, providing more efficient ejection of glass particles and, hence, reduced shielding of the machined area. IM also has smaller local angles of incidence of the laser beam that potentially can lead to a better coupling efficiency of the laser beam with the material. Full article
