Value of data
Data can be used to explain the behavior and effects of fluids on AISI316 in milling process. This dataset can be used to compare the effect of dry, wet and cryogenic responses with fluids in other machining process. The experimental data suggest the impact of fluids in reducing the temperature in tool-workpiece interface and achieving better surface finish in machining. Our data could inspire others to investigate on different materials using cryogenic machining and to carry out the comparative investigation using various fluids.
guide software). Later the data has been compared inorder to investigate the effect of responses under different considered environments. Table 1 represents the investigational conditions utilized in the present work. CNC Spark DTC-12 was used to complete processing investigates AISI 316 stainless steel. LN 2 cryogenic experimental arrangement is described in Fig. 1. Trial experiments were completed for 1000, 2000 and 3000 rpm. Constant feed rate and depth of cut of 450 mm/min, 1 mm respectively. The limit furthest reaches of parameters relied upon the preparatory investigations directed.

Method: cryogenic cooling method
An insignificant cost setup of cryogenic cooling was used to infringe the LN 2 at the tool workpiece interface. The setup incorporates TA55 cryocan, it is used to stock up the LN 2 by means of the air compressor. Flow of pressurized LN 2 is given through the specially designed nozzle to the toolworkpiece interface with the pressure of 3 bars and rate of flow of LN 2 is 0.33 l/min.

Measurement of performance characteristics
The surface roughness of each LN 2 machined surface was measured utilizing the Mitutoyo surface roughness analyzer [1,2]. Three readings at various areas were measured on each machined surface and the normal of it was considered as the definitive estimation of surface roughness estimation [3,4,6]. Infrared thermometer was used to evaluate the cutting temperatures at the instrument workpiece interface.

Cutting temperature (CT) variation in different evironments
Cooling strategies are employed by an objective to diminish the CT [7]. These are likewise help-full in keeping the cutting tools from extreme impairment like adhesion, diffusion and abrasion which are emphatically co-identified with machining temperature. In addition, at machining AISI316 at raised temperature prompts to swift device wear. The disparity attained in CT amid examination is appeared in Fig. 1. It's clear through Fig. 1 that, as the spindle rotational speed increases, the processing heat increases linearly at machining sector because of enhanced friction at device work interface. In case of LN 2 , the machining temperature was relatively cut down for considered scope of spindle speeds in contrast to dry and flood strategies. Remarkable diminishments in processing heat were seen under  LN 2 circumstance than that of other strategies (dry, flood). This is on the grounds that, the heat exchange happens amid LN 2 processing approach over convection and dissipation. Utilization of LN 2 superbly encourages the liquid beads to reach at device workpiece interface which offer a proficient warmth exchange in this manner gives enhanced lubrication prompting to low CT. Hence it may be added to prevalence of coolant particles to enter efficaciously in to the cutting zone.

Cutting force (Fx) variation in different evironments
The investigation explores divergence of Fx in dissimilar machining conditions since it show a relationships with the further crucial cut attributes, for example, tool wear, processing temperature at cutting zone, surface finish [1,5]. Fig. 2 depicts the variety in Fx response concerning processing span (time) under dry, with wet and LN 2 strategy for face milling. Fig. 2 demonstrates the Fx response which shows an expanding pattern with processing condition. It adds to warm mollifying of the workpiece at raised heat condition and spindle rotational speed. Rapid consistent processing in like way contributes in cutting down the shear quality of the workpiece and subsequently decreases the Fx. Captivatingly, LN 2 method of machining brought exceptional diminish in cutting force intensity to 43% and 16% in examination with dry, flood circumstances exclusively [7e9]. It is evident from Fig. 2, that cryogenic strategy helps in diminishment of Fx hence, attainable inferences like reduced tool wear and better external finish is achieved. Likewise, noteworthy variation in Fx is attained via flood and LN 2 mode for speed range of 1000e3000 rpm.

Investigation of flank Wear(FW) variation in different evironments
Tool wear amid processing of AISI316 was described by flank wear, in this way contemplated with the assistance of SEM. Table 2, demonstrates the movement of average FW for various processing span at the spindle speed of 1000, 2000, 3000 rpm via dry, flood and LN 2 cutting strategies. A quick development in FW seen after 60 seconds machining at spindle speed (2000e3000 rpm), particularly while machining under dry cutting condition. Then again, no huge variation was noticed at first up to 60s for all the examined scope of spindle speeds in all machining condition. However, the prevalence of using LN 2 was a prominently obvious for greater spindle speed as it enhances cooling in contrast to dry and flood strategies, thus prompts to lower FW. Along these lines LN 2 emerged as a reasonable option for machining AISI316. Table 2, exhibits the microscopic pictures of flank wear alongside machining span under all machining conditions. High substance reactivity of AISI316 prompts adhesion of the material to tool confront which brings about the creation of built up edge (BUE) [10]. The higher friction was observed in machining span of 60 seconds under strategies (dry, flood) in contrast to LN 2 . Table 2 likewise shows inclination of BUE generation was more conspicuous amid dry mode when contrasted with wet mode. Tremendous cooling in mix with great lubrication brought about critical decrease in friction and along these lines added to the remarkable cutting inserts performance especially under LN 2 mode even at higher spindle speed.

Investigation of chip morphology (CM) variation in different evironments
The CM is delivered in the milling of the workpiece was profoundly analysed with the assistance of the SEM pictures as portrayed in Fig. 3. Generally, AISI316 is described by notched chips as confirmed in Fig. 3. It is fundamentally credited to shear localisation and plastic distortion of the workpiece amid processing. In addition, processing AISI316 at elevated spindle rotational speed (3000 rpm) leads to high rate of friction at contact asperities in turn leading to higher rate of plastic deformation thus creates more notched chips via dry strategy. Along these lines, level of serration was seen to be more under dry condition when contrasted with that of wet machining condition. It may be credited to greater CT development at cutting precinct in dry strategy. Thus, high CT prompts a noteworthy upgrade in the plasticity of the machined samples [8,9]. At the other cases of machining, the distortion of the machined samples via flood and LN 2 strategy was less because of lower CT. This may be due to the side stream of chip material, as apparent through previously mentioned Fig. 3.
