Mill finish

Mill finish refers to the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes. This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil. Most mill finish surfaces are machined or treated with polishing, industrial etching, or some other surface finishing process before they are considered complete.

The quality and characteristics of mill finish can vary widely from one mill to another, and even from one lot (set of similar parts all processed consecutively or in a short time) to another. Hot rolled parts are usually dark and dull, their surface oxidized from being hot worked. Extruded products may have die marks running the length of the stock. Other mill finishes are surprisingly smooth and uniform.

It is possible for a mill to influence the finish of produced stock. Carefully maintained and polished rollers can increase the smoothness and lustre of their product, and some rolling mills will follow rolling with an annealling process to give the stock a matte finish.

Numeral prefix

Numeral or number prefixes are prefixes derived from numerals or occasionally other numbers. In English and other European languages, they are used to coin numerous series of words, such as unicycle – bicycle – tricycle, dyad – triad – decade, biped – quadruped, September – October – November – December, decimal – hexadecimal, sexagenarian – octogenarian, centipede – millipede, etc. There are two principal systems, taken from Latin and Greek, each with several subsystems; in addition, Sanskrit occupies a marginal position. There is also an international set of metric prefixes, which are used in the metric system, and which for the most part are either distorted from the forms below or not based on actual number words.

Table of number prefixes in English

In the following prefixes, a final vowel is normally dropped before a root that begins with a vowel, with the exceptions of bi-, which is bis- before a vowel, and of the other monosyllables, du-, di-, dvi-, tri-, which are invariable.

Philip Miller

Philip Miller FRS (1691 – 18 December 1771) was an English botanist of Scottish descent.

Born in Deptford or Greenwich Miller was chief gardener at the Chelsea Physic Garden from 1722 until he was pressured to retire shortly before his death. According to the botanist Peter Collinson, who visited the physic garden in July 1764 and recorded his observation in his commonplace books, Miller "has raised the reputation of the Chelsea Garden so much that it excels all the gardens of Europe for its amazing variety of plants of all orders and classes and from all climates..." He wrote The Gardener's and Florists Dictionary or a Complete System of Horticulture (1724) and The Gardener's Dictionary containing the Methods of Cultivating and Improving the Kitchen Fruit and Flower Garden, which first appeared in 1731 in an impressive folio and passed through eight expanding editions in his lifetime and was translated into Dutch by Job Baster.

Miller corresponded with other botanists, and obtained plants from all over the world, many of which he cultivated for the first time in England and is credited as their introducer. His knowledge of living plants, for which he was elected a Fellow of the Royal Society, was unsurpassed in breadth in his lifetime. He trained William Aiton, who later became head gardener at Kew, and William Forsyth, after whom Forsythia was named. The Duke of Bedford contracted him to supervise the pruning of fruit trees at Woburn Abbey and the care of his prized collection of American trees, especially evergreens, which were grown from seeds that, on Miller's suggestion, had been sent in barrels from Pennsylvania, where they had been collected by John Bartram. Through a consortium of sixty subscribers, 1733–66, the contents of Bartram's boxes introduced such American trees as Abies balsamea and Pinus rigida into English gardens.
