Chinese Journal of Mechanical Engineering

Table 1 Effect comparison of machining technology on the fatigue performance

Processes	Material	Fatigue testing method	Better process	Paramount surface integrity
Turning vs. grinding	AISI 52100 steel [6]	Axial	Turning	Residual stress
	AISI 52100 steel [7]	Rolling contact	Turning	Not clear
	AISI 52100 steel [8, 9]	Rolling contact	Turning	Residual stress
	JIS SUJ2 steel [10]	Axial	Turning	Surface roughness, work hardening
Turning vs. ECM	γ-titanium aluminide alloy [11]	Not clear	Turning	Residual stress
Milling vs. grinding	γ-titanium aluminide alloy [12]	Four-point bending	Milling	Residual stress
Milling vs. grinding	Ni-base alloy [13]	Axial	Milling	Surface roughness
Milling vs. grinding, polishing	En19 steel [14]	Three-point bending	Polishing	Surface roughness
Milling vs. grinding, polishing	Titanium alloy [15]	Four-point bending	Not clear	Non-uniformly distributed carbides
Milling vs. EDM	SAE J438b steel [16]	Three-point bending	Milling	Residual stress, phase transform
	Titanium alloy [17]	Axial	Milling	Surface roughness, recast layer
	AISI 304 stainless steel [18]	Four-point bending	EDM	Not clear
EP vs. SP, RB and DR	Titanium, aluminum, magnesium alloy [19]	Axial and rotating bending	Depend on the material
EDM vs. LBM, AWJM, milling, grinding and SP	Titanium alloy [20]	Three-point bending	SP	Residual stress

Note: ECM means electro-chemical machining, EDM means electro-discharge machining, EP means electrolytical polishing, SP means shot-peening, RB means roller-burnishing, DR means deep-rolling, LBM means laser-beam machining and AWJM means abrasive water-jet machining.
