The minimum achievable grain size and extent of alloying depend on a number of parameters i.e., type of high-energy ball mill, milling container, ball-to-powder weight ratio, milling speed, grinding medium, extent of filling of the vial, milling atmosphere, process controlling agents, milling temperature, type of material being milled etc. …

Table 1 shows a comparison of the specific energy values calculated from Eqs. () and for the 100 mesh test sieve (S = 150 µm) and seven values of G in the range of 0.33–3 g/rev.It can be seen that at a G value of 1.5 both the equations give the same estimate of the specific energy. For G values greater than 1.5 the Bond equation gives …

Ball end mills have complex geometry. The precision CNC grinding of the cutting edge on the spherical surface is a big challenge for the tool manufacturers. Regarding the design cutting edge, we propose a cutting-edge design model in which the cutting edge can be offset along the spherical surface. To improve the accuracy of this …
