Modern metal lathe A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe (/ l eɪ ð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about ...
This form tool is for a shift knob on a motorcycle. O-rings went into the grooves after machining from 6061-T6 Aluminum. This tool has an 8-degree rake from top to bottom for clearance. This tool was designed for a 2G Brown & Sharpe screw machine. A form tool is precision-ground into a pattern that resembles the part to be formed.
The Hermitage Museum, Russia, displays the Nartov's copying lathe used for ornamental turning: making medals and guilloche patterns designed by Nartov in 1721. [2] Nartov's lathe duplicated the pattern from a template to a blank, cutting to the preset scale. A probe traced the template and the cutter cut accordingly.
A view inside the enclosure of a CNC Swiss-style lathe/screw machine. A Swiss-style lathe is a specific design of lathe providing extreme accuracy (sometimes holding tolerances as small as a few tenths of a thousandth of an inch—a few micrometers). A Swiss-style lathe holds the workpiece with both a collet and a guide bushing. The collet sits ...
Important early machine tools included the slide rest lathe, screw-cutting lathe, turret lathe, milling machine, pattern tracing lathe, shaper, and metal planer, which were all in use before 1840. [12] With these machine tools the decades-old objective of producing interchangeable parts was finally realized. An important early example of ...
Turret lathe operator machining parts for transport planes, 1942. Sometimes machines similar to those above, but with power feeds and automatic turret-indexing at the end of the return stroke, are called "semi-automatic turret lathes". This nomenclature distinction is blurry and not consistently observed. The term "turret lathe" encompasses ...
The name "screw-cutting lathe" carries a taxonomic qualification on its use—it is a term of historical classification rather than one of current commercial machine tool terminology. Early lathes, many centuries ago, were not adapted to screw-cutting. Later, from the Late Middle Ages until the early nineteenth century, some lathes were ...
CAM software automates the process of converting 3D models into tool paths, the route the multiaxis machine takes to mill a part (Fig. 1). This software takes into account the different parameters of the tool head (in the case of a CNC router, this would be the bit size), dimensions of the blank, and any constraints the machine may have.
