The traditional manufacturing industry has been revolutionized with the introduction of additive which is based on layer-by-layer manufacturing. Due to these tool-free techniques, complex shape becomes much more convenient in comparison machining. However, comes its inherent process characteristics high surface roughness, turn effect fatigue strength as well residual stresses. Therefore, this p...

Investment castings (usually involving ceramic based shells) have traditionally been separated from the mould tree using an abrasive cutting operation. While material removal rates are relatively high, the process unfortunately suffers from poor accuracy control that often necessitates further finishing operations. Following an overview of key considerations in investment casting including tree...

Recent developments in grinding have opened up new avenues for finishingof hard and brittle materials with Nano-surface finish, high tolerance and accuracy.Grinding with super abrasive diamond wheels is an excellent way to produce ultraprecision surface finish. However, super abrasive diamond grits need higher bondingstrength while grinding, which metal-bonded grinding wheels ca...

Finishing methods of machining superhard composite’s working elements based on cubic boron nitride BL group are considered. The results the microgeometry formation research cutting inserts’ surfaces during by free powders synthetic diamond, grinding wheels and a method vibro-magnetic-abrasive (VMAM) presented. It is shown that VMAM friction between abrasive particles result in microremoval mate...
