5. box (square/rectangular) – this is a common guideway on machining centers and lathes. it is used in heavy machining (e.g. milling) applications. the box can either be a bolted-on steel rail or an integral part of the machine’s casting.

ball nose milling strategy guide in the loupe. jun 26, 2017 ball nose milling without a tilt angle. ball nose end mills are ideal for machining 3-dimensional contour shapes typically found in the mold and die industry, the manufacturing of turbine blades, and fulfilling general part radius requirements.to properly employ a ball nose end mill (with no tilt angle) and gain the optimal tool life

rolling of ball or wheel on the ground is an example of rolling friction. the other type of friction is sliding friction. in this type of friction, there is a restriction on the body’s movement as only one side of the body is in contact with the surface. pushing a box across the table is an example of sliding friction.
