Performance evaluation of solid lubricants in terms of machining parameters in turning

An Experimental Study on Turning of AL6063 under Cryogenic Pre Cooled Condition

“…Another thermocouple was manually touched over the work piece by inserting through a small tube fixed on the tool post which moves along with the tool. P.VamsiKrishna and D.Nageswara Rao [5] used similar method to measure the temperature at the bottom of insert. The measured temperatures are used to indicate the difference of temperature between dry ice cooled and room temperature turning and do not represent tool-work piece interface temperature at cutting zone.…”

“…R.J.Kiran et al [4] cooled the oil -water mixture to 0 o C to reduce surface roughness while turning AISI 1016 steel. P.Vamsi Krishna and D.Nageswara Rao [5] mixed graphite and boric acid in in SAE 40 oil and obtained reduced surface roughness and tool wear. Shanmugam Murugappan & Sanjivi Arul [6] pre cooled EN8 steel rod before turning to reduce surface roughness.…”

Development of electrostatic solid lubrication system for improvement in machining process performance

“…During the machining of thoroughly hardened AISI 52100 steel with ceramic inserts by using solid lubricants, it was observed that at high cutting speed range, the solid lubricants were more effective [14]. During the turning of EN8 steel workpiece with cemented carbide tool in the presence of solid lubricants (a mixture of graphite and boric acid with SAE 40 oil), cutting forces were measured to assess the lubricating properties of solid lubricants [15]. Among the lubricants, 20% boric acid in SAE 40 oil provided better performance for the selected tool-work combination and cutting conditions.…”

Investigation of Performance of Turning of Austenitic Stainless Steel Aisi 201 With Nano Boric Acid Suspended in Coconut Oil

“…Time study and cutting force were examined by Vamsi [4] when he has carried out the research in machining. He has taken solid lubricants graphite and boric acid in SAE 40 oil to carry out for investigation and measured the time taken by all the machining and compared them.…”

“…Coconut oil is selected because of thermal and oxidative properties. ANOVA analysis also give preference while changing the cutting parameters that will affect the performance of the cutting tool Time study and cutting force were examined by Vamsi [4] when he has carried out the research in machining. He has taken solid lubricants graphite and boric acid in SAE 40 oil to carry out for investigation and measured the time taken by all the machining and compared them.…”
