“…Since long chips cant not flow out smoothly over drill flutes, hence it must be avoided while broken and small type chips can be removed easily from the machined hole chip formation when drilling AISI 316L. Lowest cutting speed and lowest feed rate lead to better performance due to desirable chip formation during drilling austenitic stainless steel [15]. Since research on comparative study regarding hole characteristics and chip morphology during drilling 17-4 PH stainless steel with using uncoated and coated solid carbide drill bits is scarce.…”

17-4 PH stainless steel is one of the most imperative grades of precipitation hardened aerospace grade stainless steel particularly used in aircraft, marine vessels, nuclear industries, turbine blades, food processing equipment and oil & gas industry. It belongs to the class of difficult to cut material because of its unique properties such as high strength, high hardness and toughness including good corrosion resistance. The present study deals with comparative analysis of hole quality, surface roughness and chip characteristics when drilling 17-4 PH stainless steel with both uncoated and coated solid carbide drill bits. Dry drilling operation was carried out at two different feed of 0.10 mm/rev and 0.15 mm/rev with a constant spindle speed of 2000 RPM. Results indicated that surface finish and burr thickness could not be improved, while remarkable reduction in hole diameter and delamination factor was noted for the coated solid carbide drill bit compared to its uncoated counterparts for different machining conditions.

“…Parameters of machining that are essential include cutting speed, feed rate and depth of cut. Experimental work was conducted by Sultan et al [5] to identify the optimum cutting speed and feed rate for discontinuous chip formation with a drilling process. It was found that the lowest cutting speed as well as feed rate produced the best performance in regards to chip formation.…”

“…The better performances, such as desirable chip formation, can be gained at the lowest cutting speed and feed rates in drilling operations. 3,14 Discontinuous plastic deformation leads to the fan-shaped and breakup removal chips, in the cutting zone, at lower spindle speed during the drilling operations. However, at medium spindle speeds, the breakup chips, and sequential short helical chip forms are converted into long helical chips.…”

The differences in the cutting speed are a serious problem along the cutting edge of the drill, in drilling operations. This problem can partly be solved reducing the length of the cutting edge via changing the drill point angle. In addition, in this study, the effect of point angle, feed rate, and cutting speed on drilling is investigated. For identifying the optimum cutting parameters, AISI 1050 steel alloy was selected as the experimental specimen, these specimen were pre-drilled 5 mm in diameter due to eliminating the effect of the chisel edge. In the experiments, the holes were drilled only at a depth of 10 mm in order not to give any harm to the dynamometer while measuring thrust force. For this aim, in drilling process, drills with point angle of 100°, 118°, 136°, 154°, and 172° were selected. In conclusion, the thrust force, the tool wear, and the surface roughness linearly decreased with increasing point angles due to less removal chip area, in per revolve of the tool. However, the thrust force, the tool wear, and the surface roughness were adversely affected at higher feed rates and lower cutting speeds. The hole dimensional accuracy decreased at lower feed rates and cutting speeds but at higher point angles and concurrently at higher feed rates but lower point angles and cutting speeds. However, the hole dimensional accuracy showed more decisiveness at 118° than other point angles, while the highest dimensional accuracy values recorded at 136° point angle, at higher cutting speeds.
