Over the last two decades, improvements such as those made in cutting materials have led to an approximately eightfold increase in the drive power of milling spindles (Fig. 4).

The marine animal waxes are both solid and liquid. The solid marine animal waxes are represented by a wax of considerable economic importance, namely spermaceti, derived from a concrete obtained from the head of the sperm whale. The liquid waxes of marine animals arc represented by speim oil obtained from the blubbei and cavities in the head of the sperm whale. Spermaceti is the wax used in the candle which defines our unit of candle power it is used chiefly as a base for ointments, cerates, etc. Sperm oil contains a considerable amount of esters made up of unsaturated alcohols and acids, both of which are susceptible to hydrogenation. Hydrogenated sperm oil is the equivalent of spermaceti wax and harder than the commercial pressed spermaceti. Both yield cetyl alcohol as the unsaponifiable. There is a fairly large demand for cetyl alcohol in the manufacture of lipstick, shampoo, and other cosmetics. Sperm oil itself is an excellent lubricant for lubricating spindles of cotton and woolen mills, or wherever there is need for a very light, limpid, nongummmg lubricant. 

For proper control in sugar manufacture, the laboratory must be well-equipped with accurate scales, saccharimeter (polariscope), and the Brix spindle or refractometer. The laboratory control of factory operations, from milling to final product, basically depends on the following three operations. 

Milling machines can generally be classified according to the orientation of the spindle, either vertical or hor-... 

Boring machines are similar in construction to milling machines except they are generally more massive and built lower to the floor, use different tooling, and feed differently along the axis of the spindle. Boring machines are typically located in very clean, climate controlled environments and are massive for extra rigidity and vibration...

The transfer function between the actual feed and the peak resultant cutting force is usually modeled as a first-order lag in a stable cutting process. The peak force is detected usually at one spindle period in order to avoid run-out effects in multipoint cutting operations such as drilling and milling. The overall discrete transfer function between the feed command (fc) and peak force (Fp) is considered to represent the combined dynamics of CNC, feed drives, and cutting process, and may be represented as follows ...
