Development Of Environmentally Friendly Biodegradable Cutting Fluid From Soya Beans (Glycine Max)

Abstract

In this work, cutting fluid conflation was developed from soya sap and the performance of the developed slice fluid was estimated by comparison with the conventional slice fluid( control sample), using its capability to effectively perform as coolant during machining operation. The machining operation employed was the turning operation in which chips produced were collected and their face finishes measured. The chips collected were estimated for chip consistence rate. Also, the temperature variations during cutting operation were measured using an infra-red gun thermometer. Temperature, face finishing as well as chip conformation rates using the developed slice fluid under different slice speed( rev/ min), feed rate( mm/ rev) and depth of cut( mm) was compared with that of the conventional slice fluid. The average temperature of the work piece when developed cutting fluid was used as cutting fluid was53.13 oC and that of the conventional slice fluid was54.7 oC. The result are veritably near, hence it shows better result in conducting heat down from cutting region. The developed slice fluid gave an average high chip consistence of0.446 mm while that of the conventional slice fluid was set up to be0.316 mm. The high chip consistence of the developed slice fluid is presumably due to its better slicking capability which allows easier and deep penetration of cutting tools. The average density of the developed slice fluid was set up to be31.1 poise at 29 oC, while the convectional slice fluid was 47 poise at 29 oC. Low density means high density indicator, the developed slice fluid has tendency to be fluid at advanced temperature than the convectional fluid. In erosion dimension, the developed slice fluid shows no sign of erosion; hence, the fluid has good capability to inhibit erosion than the convectional slice fluid.

Background of the Study

The use of slice fluids in essence slice was first reported in 1894 byF. Taylor who noticed that cutting speed could be increased by 33 without reducing tool life by applying large quantities of water in the slice zone( Ávila and Abrao, 2001). Cutting fluids increase tool life and ameliorate the effectiveness of the product systems furnishing both cooling and lubrication of the work face.

Cutting fluids are used to reduce the negative goods of heat and disunion on both tool and work piece. Cutting fluids produce three positive goods on the process heat junking, lubrication on the chip – tool interface and chip junking( Lopez de Lacalle etal., 2006). still, the advantages caused by the slice fluids have been questioned recently, due to the several negative goods they’ve caused to in the terrain and worker ‟ s health.

When erroneously discharged, cutting fluids may damage soil and water coffers, causing serious environmental impact. On the shop bottom, machine drivers may be affected by negative goods of slice fluids, similar as skin and respiratory problems( Lopez de Lacalle etal., 2006). In order to make the machining process more ecologically friendly, a near- dryapplication of lubricant have been accepted because of its environmentally friendly characteristics( Sokovic etal., 2001, Dhar etal., 2006 and Suda etal., 2004). But, depending on the machining process, to reduce or exclude slice fluids use isn’t possible. For these cases it’s necessary to develop an indispensable result in order to avoid terrain and champaign damage.
