EFFECT OF DIFFERENT MACHINING PARAMETERS ON DRY MACHINING

Mechanical Engineering

The emergence of government legislations in environmental matters has lead to the minimization of use of cutting fluids in machining processes making the study of dry turning process important. Several researchers’ state that the costs related to cutting fluids is frequently higher than those related to cutting tools. Considering the high cost associated with the use of cutting fluids and projected costs when the stricter environmental laws are enforced, alternatives have been sought to minimize or even avoid the use of cutting fluid in machining operations leading importance to the study of dry turning process. Dry machining is now of great interest and actually, they meet with success in the field of green (eco-friendly) manufacturing. Many plant managers know of the non-value added costs associated with flood coolants – part cleaning, frequent floor cleaning, absorbent mats, coolant additives such as biocides, chip cleaning, etc. With Near-Dry Machining (also known as Minimal Quantity Lubrication), there are no flood coolants. Just a small amount of atomized cutting fluid is applied directly to the cutting interface. Typical fluid consumption is less than 10 ml per hour per nozzle and the chips are dry to the touch (0.2% oil content). In this seminar report, focus is given on need, literature review, cost analysis between cutting fluids and tool used, ten commandments and latest trends dry machining.
