“…In addition to grinding force, grinding zone temperature plays a significant role in determining the surface integrity of the material too. The factors such as velocity, feed, depth of cut, grit size and method of lubrication determine the amount of heat developed in the grinding zone [ 1 ]. The grinding zone temperature against the depth of cut with various cutting velocities is shown in Figure 3 .…”

“…Typically, they have a high amount of nickel along with other alloying elements such as cobalt, molybdenum and a small amount of titanium and carbon. As the high strength and fracture toughness of this material can be retained over a range of temperatures, they are regularly being utilized in aviation, maritime vessels and tooling ventures [ 1 ]. The high strength of maraging steel is normally associated with the precipitation of intermetallic compounds.…”

Additive manufacturing (AM) is replacing conventional manufacturing techniques due to its ability to manufacture complex structures with near-net shape and reduced material wastage. However, the poor surface integrity of the AM parts deteriorates the service life of the components. The AM parts should be subjected to post-processing treatment for improving surface integrity and fatigue life. In this research, maraging steel is printed using direct metal laser sintering (DMLS) process and the influence of grinding on the fatigue life of this additively manufactured material was investigated. For this purpose, the grinding experiments were performed under two different grinding environments such as dry and cryogenic conditions using a cubic boron nitride (CBN) grinding wheel. The results revealed that surface roughness could be reduced by about 87% under cryogenic condition over dry grinding. The fatigue tests carried out on the additive manufactured materials exposed a substantial increase of about 170% in their fatigue life when subjected to cryogenic grinding.

“…To the grinding wheel, cubic Boron Nitride (cBN) abrasive is an attractive choice for machining difficult-to-cut material because of high cutting capacity and less thermal failure. Additionally, resin-bonded cBN wheels are usually used as it can obtain high surface quality and possesses good impact strength [2]. An internal evolved porous composite-bonded cBN wheel with graphene nanoplatelets was investigated by Chen et al [3].…”

The experiments of the surface grinding of Ti-6Al-4V grade 5 alloy (Ti-64) with a resin-bonded cubic Boron Nitride (cBN) grinding wheel are performed in this research to estimate the influence of cutting parameters named workpiece infeed speed, Depth of Cut (DOC), cooling condition on the grinding force, force ratio, and specific energy. A finite element simulation model of single-grain grinding of Ti-64 is also implemented in order to predict the values of grinding forces and temperature. The experimental results show that an increase of workpiece infeed speed creates higher intensified cutting forces than the DOC. The grinding experiments under wet conditions present slightly lower tangential forces, force ratio, and specific energy than those in dry grinding. The simulation outcomes exhibit that the relative deviation of simulated and experimental forces is in the range of 1-15%. The increase in feed rate considerably reduces grinding temperature, while enhancement of DOC elevates the heat generation in the cutting zone.

Основний обсяг досліджень виконано на сталях Н8К18М12 (мартенситно-старіюча, маловуглецева) і12Х2Н4А (вуглецева цементована та загартована). В результаті проведених експериментів встановлено, що силирізання при шліфуванні кругами з електрокорунду, кубічного нітриду бора (КНБ) і алмазу досягають значнихвеличин. Встановлено, що сили різання Ру і Рz в діапазоні режимів, які переважно застосовуються при плоскомута круглому шліфуванні можуть досягати величин відповідно Ру = 30Н, Рz = 20Н. При шліфуванні сталі Н8К18М12сили різання на 20 ... 50% вищі, в порівнянні з силами різання при шліфуванні вуглецевих цементованих ізагартованих сталей.
