Effect of the lubrication-cooling technique, insert technology and machine bed material on the workpart surface finish and tool wear in finish turning of AISI 420B

Optimization of Cutting Parameters, Condition and Geometry in Turning AISI 316L Stainless Steel Using the Grey-Based Taguchi Method

“…Machine turning applications, which use cooling techniques that respect human health and the environment, have been developed. The performance characteristics of the alternative cooling technique were found to be superior to the conventional cooling techniques [1,[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The MQL technique which delivers reduced tool wear and improved surface quality thanks to a reduction in the heat generated in the tool-chip and workpiece-chip cutting zone are important results [23].…”

Experimental Investigation of Machinability Characteristics Under Minimum Quantity Lubrication Using Graphene Based Nano-Cutting Fluid.

“…Machining involves withdrawal of excess material from the workpiece by forcing of the cutting tool against the workpiece in order to obtain desired shape, size and surface finish of the workpiece. When ferrous materials are machined the cutting temperature increases with cutting velocity which results in softening of cutting tool leading to rapid wear and failure of the cutting tool (Bruni et al, 2006). Since high cutting speed is preferable for obtaining higher productivity so the generated heat has to be dissipated continuously around the cutting zone to maintain the sharpness of the cutting edge of the tool.…”

Performance evaluation of coated carbide tool in machining of stainless steel (AISI 202) under minimum quantity lubrication (MQL)

“…However, few disadvantages make the MQL-based machining process impractical to be adopted in many industrial production settings. 6 The review of literature has revealed that majority of work on MQL machining has carried out on various grades of hardened alloy steels: AISI-1040, AISI 1045, AISI 1060, AISI-4340, Ni-Cr alloys like Inconel 718, brass and aluminum alloy 6061and titanium etc., [7][8][9][10][11][12][13][14][15][16] and a few researchers have explored MQL machining potential of stainless steel grades. Leppert 17 investigated surface layer properties of AISI 316L stainless steel when turning under dry and MQL conditions.…”

“…MQL turning at low feed rates and used cutting speeds resulted in lower Ra = 1.34-1.50 µm compared to dry turning, Ra = 1.54-1.82 µm and with emulsion Ra = 1.68-2.26 µm and more homogeneous machined surface with fewer defects. Bruni et al 7 during investigating effect of the lubrication-cooling technique, on workpart surface finish of AISI 420B stainless steel reported that highest influence in all cooling and lubricating conditions was exerted by the feed rate. Apart from above, no information is available on turning of Stainless Steel (AISI 202) with economical coated carbide tools under MQL conditions.…”
