Creep feed grinding is a recently invented process of material handling. It combines high quality of the piece surface, productivity, and the possibility of automatic control. The main objectives of this research is to study the influences of major process parameters and their interactions of creep feed grinding process such as wheel speed, workpiece speed, grinding depth, and dresser speed on the pin gauge dimensions of root of gas turbine blade by design of experiments (DOE). Experimental results are analyzed by analysis of variance (ANOVA) and empirical models of pin gauge dimensions of root are developed. The study found that higher wheel speed along with slower workpiece speed, lower grinding depth and higher dresser speed, cause to obtain best conditions for pin gauge dimensions of root.

“…Lavine et al [8] presented a conical grain model, with grain slope set to one. Lavine and Jen [9] derived a separate thermal model among the fluid, wheel and workpiece to predict the occurrence of boiling. Shafto et al [10] suggested that the fluid for creep feed grinding carries most of the heat away, and less than 5% of heat remains in the workpiece as the coolant of water is applied.…”

“…In a previous study of Wang and Kou [12], the results showed that the cooling effect of water is better than that of oil, and most of heat generated could be carried away by water. Almost all of the prior analyses [3,4,5,6,7,8,9] neglected the conduction effect of the workpiece in the moving direction. Therefore, to give the whole picture of creep feed grinding, this conduction effect is considered here.…”

A thermal model focused on the heat transfer to the fluid, workpiece and grain is developed for creep feed grinding. In this model, the conduction effect in the moving direction of the workpiece is considered which is found to be very significant especially for creep feed grinding. Moreover, the thermal partition ratios to the workpiece, fluid and grain are well defined and discussed. The results reveal that the cooling effect of the fluid is more crucial especially at larger grinding depth and smaller workpiece speed. Furthermore, the promotion of the wheel speed is helpful to reduce the fraction of heat entering the workpiece. Also, the workpiece thermal partition ratio is greatly influenced by the workpiece speed. Its value is even less than 5% as the workpiece speed is smaller than 4 mm/s. Comparing the thermal partition of wet grinding to that of dry grinding, the abrupt increase of heat entering the wheel and workpiece due to the occurrence of boiling in the fluid is verified.

The recent model for heat transfer during intermittent grinding described in Skuratov, Ratis, Selezneva, Pérez, Fernández de Córdoba and Urchueguía (Appl Math Model 31:1039-1047, 2007 is considered. This model is particularized to the case of continuous dry grinding, where an alternative solution is obtained in the steady state. This alternative solution is analytically equivalent to the well-known formula of Jaeger (Proc R Soc NSW 76:204-224, 1942) for the steady-state temperature field created by an infinite moving source of heat and proves to be very useful for evaluating the maximum point of the temperature.
