“…The maximum hole perpendicularity error value occurred at a feed rate of f = 900 mm/ min and was minimum at a feed rate of f = 300 mm/min. Similar trends were observed by previous researchers when drilling aluminum and titanium alloys [42,43]. Generally, it was observed that hole perpendicularity error increased with the increase of the feed rate for all depths of cuts which is mainly due to the increase in the feed force as it can be seen from Fig.…”

“…Previous studies investigated the effect of cutting parameters, tool coating, tool geometry, and coolants on hole perpendicularity error for a variety of metallic materials such as steel, aluminum, and titanium alloys [37][38][39][40][41][42][43][44][45][46] and composite materials [36,47]. The studies found that three most significant variables on hole perpendicularity error were cutting speed, feed rate, and depth of cut [40][41][42][48][49][50]. Other studies reported that the application of machining coolants did not have an influence on the hole dimensional and positional accuracy such as its perpendicularity error and cylindricity expect for certain cases, which was mainly attributed to the size and type of cutting tool used [40].…”

Conventional twist drilling is a widely used machining process for creating holes in aerospace and automobile structures. Drilling at room temperature can sometime affect the quality of machined holes due to increased thermal effects on the workpiece. Thermal effects can be a cumbersome when machining composites and fiber metal laminates due to their different thermal expansion coefficients, which may introduce additional stress in the structure. Thermal machining effects can be minimized using coolants supplied either directly or indirectly to the cutting tool-workpiece interaction zone, to remove away part of the generated heat. The use of coolants adds extra costs for handling, disposal, and environmental impact. Therefore, environmentally friendly cooling technologies are replacing conventional cooling methods to reduce costs and impact on the environment. In addition, the selection of machining parameters has great influence on the hole quality. This paper investigates the impact of drilling parameters and two modern cooling technologies namely cryogenic liquid nitrogen and minimum quantity lubrication on the hole perpendicularity error of fiber metal laminates commercially known as GLARE® (Glass Laminate Aluminum Reinforced Epoxy). It was also found that applying cryogenic liquid nitrogen or minimum quantity lubrication does not lead to an improvement in hole perpendicularity error in GLARE® laminates.

“…High temperature in the machining process of such steel limits the usage of carbide cutting tools if effective cooling and/or lubrication are not implemented [1]. The conventional cooling approach is accepted as an effective way for most applications, but from an environmental standpoint, it is not always the way preferred by the machining community [3][4][5]. Therefore, dry machining [6] is used in the machining process of hardened steel [7].…”

This experimental study focuses on various cooling strategies and lubrication-assisted cooling strategies to improve machining performance in the turning process of AISI 4140 steel. Liquid nitrogen (LN 2) and carbon dioxide (CO 2) were used as cryogenic coolants, and their performances were compared with respect to progression of tool wear. Minimum quantity lubrication (MQL) was also used with carbon dioxide. Progression of wear, including flank and nose, are the main outputs examined during experimental study. This study illustrates that carbon dioxide-assisted cryogenic machining alone and with minimum quantity lubrication does not contribute to decreasing the progression of wear within selected cutting conditions. This study also showed that carbon dioxide-assisted cryogenic machining helps to increase chip breakability. Liquid nitrogen-assisted cryogenic machining results in a reduction of tool wear, including flank and nose wear, in the machining process of AISI 4140 steel material. It was also observed that in the machining process of this material at a cutting speed of 80 m/min, built-up edges occurred in both cryogenic cooling conditions. Additionally, chip flow damage occurs in particularly dry machining.

Optimization of process parameters in reaming operation is used mainly to reduce the production cost in industries. The current study focuses on the optimization effect of process parameters in cryogenic reaming of Titanium alloy. The input factors considered are cooling environment, cutting speed and feed rate. The effects of reaming parameters are cutting temperature, thrust force, torque, surface roughness, circularity and cylindricity. Multi response optimization-Grey relational analysis is used to optimize the process parameters. The smaller the better is used to minimize the better output responses and to find out the most significant factor affecting the reaming operation. As a result, the lower level parameter cutting speed 10 m/min and feed rate 0.1 mm/rev under cryogenic LN 2 cooling are found to be optimal conditions. The most significant factors (higher to lower) which affect the reaming operations are feed rate, cutting speed and cooling environment.
