“…For example, the drilling of AISI 1040 steel with high speed steel (HSS) drills under MQL conditions was found to improve the accuracy with an average temperature reduction of 10% at the tool chip interface in addition to providing the best hole surface texture [85]. Zeilmann et al conducted drilling tests on AISI P20 steel using carbide drills with different drilling conditions being applied during machining, namely dry, emulsion and MQL [86]. Continuous drilling was adopted for the emulsion case whereas a pecking cycle was used for both dry and MQL conditions with an advance of 1.5 mm followed by a retreat out of the hole.…”

Government legislation and public opinion are the main drivers behind the movement of manufacturing companies towards sustainable production. Fundamentally, companies want to avoid future financial penalties and the industry is therefore under pressure to adapt new techniques and practices in order to become environmentally friendly. The cost efficiency of metal cutting operations is highly dependent on accuracy, excellent surface finish and minimised tool wear and, to this end, has traditionally made abundant use of cutting fluid in machining operations. However, these cutting fluids have been a major contributor to environmental and health issues. In recent years an enormous effort to eradicate these adverse effects has been made with one important focus being the implementation of minimum quantity lubrication (MQL). In the present work the authors have reviewed the current state of the art in MQL with a particular focus on drilling, turning, milling and grinding machining operations.Overall it is concluded that MQL has huge potential as a substitute for conventional flood cooling.

Drilling is one of the machining processes most used by manufacturing companies and is very complex from the perspective of scientific study. The geometry and the surface are generated in a single operation with many influential parameters. Geometric and dimensional control are more critical when the use of cutting fluids is reduced or eliminated because the temperatures in the process can influence the shape and the dimensional accuracy of the holes. However, this influence is not completely understood. With this goal, this article presents a dimensional analysis of holes made with carbide drills in AISI P20 steel under the fluid application of emulsion, minimal quantities of lubricant and dry machining. The dimensional parameters analyzed were the diameter and the circularity of the holes. Special highlight can be given to shape results, which were evaluated at different depths (beginning, middle and end of the hole), and along the evolution of the number of holes. Some differences of the investigated results compared to the literature are due to the formation of adhesion on the wall of the hole, resulting from passage of the edge on this particular severity condition.

“…A certain amount of the buildup may result in the severe chip clogging leading to the failure of a drill. When chips produced in MQL drilling cannot be efficiently evacuated from a drilling hole, pecking is often effective to extend tool life, e.g., MQL drilling of aluminum-silicon alloy containing 6% silicon with a DLC coated drill (49) and MQL drilling of hardened plastic mold steel (AISI P20 steel) of 36-38 HRC with a coated carbide drill (50). Thus, MQL drilling is not as effective as not only MQL milling but also MQL turning, unless cooling and lubrication in MQL drilling are not enough for the combination of the work and tool materials and adopted cutting conditions.…”
