when the ball is at the topmost point in the mill If ' R ' is the radius of the mill and ' r ' the radius of the ball (grinding medium), from force balance at the topmost point, the analytical expression for the critical speed for a ball mill comes to be where g is the acceleration due to gravity. Ball mills are usually operated at around 65 – 75 % of their critical speed

Ball nose spiral end mills are used for smooth contouring and fine detail passes with a CNC router and often for complex shapes like 3D carvings. The rounded ends produce smooth curves that would be impossible to achieve with flat end bits. Small diameter ball nose end mills are used for projects with intricate detail while larger bits are used for smoother projects with more gradual slopes ...

A hole of radius 1 is drilled into the centre of a sphere of radius 2. Calculate the remaining volume. Could someone explain to me how to approach this. I don't need a specific answer. I know it involves integration but my method creates a doughnut shape revolving around the xaxis and that's clearly not right. Thanks ! EDIT:

Ball end mills are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multidimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. Because of the shapes required in these products it's common that multi axis machining
