“…The surface roughness of machined workpiece with coolant is decreased in comparison to the dry turning operations of Titanium alloy Ti6Al4V. The built-up edge (BUE) is generated during dry machining which can cause cutting tool inserts to drag over the surface of machined components and can decrease the surface quality of machined parts (Patel and Patil 2022). The coolant reduces cutting temperature in the contact zone of the cutting tool and workpiece and prevents the formation of BUE which can increase the surface quality of machined components.…”

The titanium alloys are widely used in aeronautical engineering and medical device materials due to exceptional mechanical properties such as tensile resistance and toughness of fractures. High thermo-mechanical loads occur in metal cutting of Titanium alloy Ti6Al4V, which can decrease life of cutting tool and increase cost of part production. In this paper, the coolant effects on the cutting temperature, surface roughness and tool wear are investigated by using the developed virtual machining system. The cutting forces during turning operations of Ti6Al4V alloy are accurately calculated in order to be used in calculation of cutting temperature and tool wear. The modified Johnson-Cook methodology is utilized to obtain the cutting temperatures along machining paths. Then, the Coupled Eulerian-Lagrangian (CEL) approach is investigated to predict and evaluate the effects of coolants on the cutting temperature in turning operations of Ti6Al4V alloy. The finite element approach is employed to predict tool wear by using the Takeyama-Murata analytical model and modifying the cutting tool geometry during the chip production process. To verify the developed methodology in the study, the results of experiments for the measured cutting temperatures, surface quality and wear rate are compared to the results of virtual machining system obtained by the finite element simulation. Thus, utilizing the proposed virtual machining system in the study, cutting temperatures, surface quality and tool wear during the turning operations of Ti6Al4V alloys with and without coolant can be accurately predicted to enhance the accuracy as well as productivity in the CNC machining operations.

“…(1) Dry cutting of cast iron: Dry cutting of cast iron is a major progress in technology, and the chips will adhere to the tool during cast iron processing, which will cause sharp wear of the tool; Attachment to the workpiece will reduce the machining accuracy of the surface of the workpiece [14] ; Adhesion to the moving parts of the machine tool will cause problems such as wear of the guide rail of the machine tool and blockage of the cooling system, so cast iron machining usually does not use cutting fluid, and dry machining is used.…”
