Straight Line Engine Turning
A straight line engine turning machine is a machine used for engraving decorative patterns on a surface. The engraving may be referred to as Guilloché, which also encompasses patterns created with the rose engine lathe A rose engine lathe is a specialized kind of geometric lathe. The head stock rocks back and forth with a rocking motion and/or slides along the spindle axis in a pumping motion. A rosette or cam-like pattern mounted on the spindle is controlled .... Where the rose engine is based on a lathe, the straight line engine has more in common with a metal planer machine. The straight line engine turning machine commonly consisted of an upright slide, a cross slide, a slide rest which holds the cutting tool, and a pattern bar holder References Lathes {{Engineering-stub ...

Engraving
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article, same with rock engravings like petroglyphs. Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning the technique, is much less common in printmaking, wher ...

Guilloché
Guilloché (; or guilloche) is a decorative technique in which a very precise, intricate and repetitive pattern is mechanically engraved into an underlying material via engine turning, which uses a machine of the same name, also called a rose engine lathe. This mechanical technique improved on more time-consuming designs achieved by hand and allowed for greater delicacy, precision, and closeness of line, as well as greater speed. The term ''guilloche'' is also used more generally for repetitive architectural patterns of intersecting or overlapping spirals or other shapes, as used in the Ancient Near East, classical Greece and Rome and neo-classical architecture, and Early Medieval interlace decoration in Anglo-Saxon art and elsewhere. Medieval Cosmatesque stone inlay designs with two ribbons winding around a series of regular central points are very often called guilloche. These central points are often blank, but may contain a figure, such as a rose. These senses are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rose Engine Lathe
A rose engine lathe is a specialized kind of geometric lathe. The head stock rocks back and forth with a rocking motion and/or slides along the spindle axis in a pumping motion. A rosette or cam-like pattern mounted on the spindle is controlled by moving against a cam follower(s) while the lathe spindle rotates. Rose engine work can make flower patterns, as well as convoluted, symmetrical, multi-lobed geometric patterns. The patterns it produces are similar to that of a Spirograph, in metal. No other ornamental lathe can produce these "rose" patterns. The decoration produced by a rose engine lathe is called guilloche. It sometimes confused with "jewel finishes" or engine turning, a much cheaper process of making swirly marks in metal by a rotating abrasive peg or pad, which is repeatedly applied to the surface to make a pattern of overlapping circles. Jewel finishes used to be common on stereo faceplates and automobile interiors. The patterns of United Kingdom's first postag ...

Planer (metalworking)
A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' p. 73, Cypress, CA, 2013. . A planer is similar to a shaper, but larger, and with workpiece moving, whereas in a shaper the cutting tool moves. Applications Linear planing The most common applications of planers and shapers are linear-toolpath ones, such as: * Generating accurate flat surfaces. (While not as precise as grinding, a planer can remove a tremendous amount of material in one pass with high accuracy.) * Cutting slots (such as keyways). * It is even possible to do work that might now be done by wire EDM in some cases. Starting from a drilled or cored hole, a planer with a boring-bar type tool can cut internal features that don't lend themselves to milling or boring (such as irregularly shaped holes with tight c ...
