Effect of Cutting Fluid Application:

Machining might be done either in the wet condition (utilization of cutting fluid in the cutting zone) or dry condition. utilization of a right kind of cutting fluid develop machining operation from a complex cooling and lubricating mechanism, that affects the cutting force (along with tool life) and the machined surface roughness. Figure 10 illustrated that F_c enhance with a enhance in uncut chip thickness however it decreases relative to dry cutting. this is also seen from Figure 10 that in certain kind of cutting fluid, the force F_c might be lower than the other kind of cutting fluid.

On the forces Influence of tool wear is also important in the machining of ductile material along with brittle material. As wear land (on the flank face) enhances, friction among tool and workpiece enhance. Although, there is an prime dip in the relationship. This is so because in the beginning, crater wear also occur on the rake face of the tool, that increases its effective rake angle therefore decreases the cutting force. Upon further enhance in flank wear along with crater wear, the flank wear dominates therefore the forces enhance.
