An Experimental Investigation of Effect of Cutting Fluids on Chip Formation and Cycle Time in Turning of EN-24 and EN-31 Material

In metal cutting industries it is essential to study the chip morphology during machining process. The chip formation is not only depending upon the work piece material but even on the cutting fluids and grain structure of the materials. Cutting fluids have seen extensive use and have commonly been viewed as a required addition to high productivity and high quality machining operations. This experiment is to determining the effect of cutting fluids and cutting parameters on chip formation mode and cycle time in turning of EN-24 and EN-31 material. The above operation has been carried out in dry cutting condition, Flood application of cutting fluids. Cutting fluids like soluble oil and palm oil used in the present work. The cutting operations were carried out on a conventional lathe machine there by making turning operation with uncoated carbide cutting tool at different spindle speed(n) of 210rpm, 450rpm and 750rpm.Also feed(f) of 0.1rev/min to 0.2rev/min. Depth of cut is kept constant at 1.5mm. By using the vegetable oil we can improve the surface finish, metal removal rate and to reduce the environmental effects. After conducting these experiments it was recorded chip morphology and cycle time value for each fluid under different cutting conditions. It was observed light color chips with segmented form in vegetable based oil at lower cutting conditions for each material.
