A special issue of International Journal of Machining and Machinability of Materials
The basic functions of a metal working (cutting) fluid (hereafter MWF) or simply the coolant are to provide cooling and lubrication and thus reducing the severity of the contact processes at the cutting tool–chip and cutting tool–workpiece interfaces. It is expected that MWF should also provide secondary service actions such as, for example, washing of the machined part or chip transportations as in deep-hole drilling where MWF transports the chip over significant distances. However, the cost of using MWFs is increasing as the number and the extensiveness of environmental protection laws and regulations increase. Although recent changes in MWF formulations have resulted in safer products, it is important to realise that MWFs may cause a variety of health problems. Ecological and health aspects of metalworking fluids' manufacture, use and disposal become very important due to new stricter legislation, notably in Europe.
At present, many efforts are being undertaken to develop advanced machining processes using less or no MWFs. High-pressure through-tool MWF supply, near dry machining (MQL) and dry machining have become popular avenues for reducing and/or eliminating the problems and cost associated with the MWF management. It has become apparent that, to make these technologies reliable, environmentally friendly and cost efficient, the whole picture has to be considered. Their success can be achieved if all components of machining or manufacturing system are suitable for these technologies.
This special issue invites the submission of high quality research papers related to various aspects of high-pressure through tool MWF supply, near dry machining (MQL) and dry machining.
Suitable topics include, but are not limited to, the following:
- Physical and tribological processes in near dry machining (MQL) and dry machining at the tool-chip and tool-workpiece interfaces: modelling, experimental studies and optimization.
- Design of the special cutting tools and apparatuses (nozzles, atomizers, holders, control and pre-setting units).
- Advanced concepts and methods, for example the "oil on water droplet", referred as OoW NDM, and advanced minimum quantity cooling lubrication NDM, referred as AMQCL.
- Advanced MWFs including bio-based, biodegradable, nanofluids etc.
- Implementation issues near dry machining (MQL) and dry machining in manufacturing cells and CNC machines.
- Ecological and health impacts.
