Jig (tool)

In metalworking, a jig is a type of custom-made tool used to control the location and/or motion of another tool.

Description

A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products. A jig is often confused with a fixture; a fixture holds the work in a fixed location. A device that does both functions (holding the work and guiding a tool) is called a jig.

An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one. Since the advent of automation and computer numerical controlled (CNC) machines, jigs are often not required because the tool path is digitally programmed and stored in memory. Jigs may be made for reforming plastics.

Jigs or templates have been known long before the industrial age. There are many types of jigs, and each one is custom-tailored to do a specific job. Many jigs are created because there is a necessity to do so by the tradesmen. Some are made to increase productivity through consistency, to do repetitive activities or to do a job more precisely. Jigs may be well made for frequent use or may be improvised from scrap for a single project, depending on the task.

Jig

The Jig (Irish: port) is a form of lively folk dance in compound meter, as well as the accompanying dance tune. It developed in 16th-century England, and was quickly adopted on the Continent where it eventually became the final movement of the mature Baroque dance suite (the French gigue; Italian and Spanish giga). Today it is most associated with Irish dance music, Scottish country dance and the Métis people in Canada. Jigs were originally in duple compound meter, (e.g., 12
8 time), but have been adapted to a variety of time signatures, by which they are often classified into groups, including light jigs, slip jigs, single jigs, double jigs, and treble jigs.

Origins

The term jig was probably derived from the French giguer, meaning 'to jump' or the Italian giga. It was known as a dance in 16th-century England, often in 12
8 time, and the term was used for a post-play entertainment featuring dance in early modern England, but which 'probably employed a great variety of dances, solo (suitable for jigs), paired, round, country or courtly': in Playford's Dancing Master (1651) 'the dance game in ‘Kemps Jegg’ is a typical scenario from a dramatic jig and it is likely that the combination of dance metre for steps and non-metrical passages for pantomime indicates how a solo or ensemble jig might have been danced by stage players.' Later the dance began to be associated with music particularly in 6
8 time, and with slip jigs 9
8 time.

Jig (jewellery)

A jig used in making jewelry, a specific type of jig, is a plate or open frame for holding work and helping to shape jewelry components made out of wire or small sheets of metal. A jig in the jewelry making application is used to help establish a pattern for use in shaping the wire or sheets of metal. In the jewelry application, the shaping of the metal is done by hand or with simple hand tools like a hammer.

History

The use of wire in making jewelry is something that can be seen in jewelry from the Sumerian Dynasty of Ur about 2560 BC.  The British Museum has examples of jewelry obtained from the Royal Cemetery of Ur (Iraq) that include wire spirals.  Examples of wire and sheet metal jewelry can also be found in jewelry from Ancient Egypt and Ancient Rome. While we have no examples of jigs or patterns being used to make that jewelry, one can surmise that sometime after the Sumerians, but likely before the Romans that patterns made out of carved wood were used to shape jewelry components. re the same technique we use in our knitting today.

Tool

A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools.

Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", "device," or "apparatus". The set of tools needed to achieve a goal is "equipment". The knowledge of constructing, obtaining and using tools is technology.

History

Anthropologists believe that the use of tools was an important step in the evolution of mankind. Because tools are used extensively by both humans and wild chimpanzees, it is widely assumed that the first routine use of tools took place prior to the divergence between the two species. These early tools, however, were likely made of perishable materials such as sticks, or consisted of unmodified stones that cannot be distinguished from other stones as tools.

Stone artifacts only date back to about 2.5 million years ago. However, a 2010 study suggests the hominin species Australopithecus afarensis ate meat by carving animal carcasses with stone implements. This finding pushes back the earliest known use of stone tools among hominins to about 3.4 million years ago.

Programming tool

A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications. The term usually refers to relatively simple programs, that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object. The ability to use a variety of tools productively is one hallmark of a skilled software engineer.

The most basic tools are a source code editor and a compiler or interpreter, which are used ubiquitously and continuously. Other tools are used more or less depending on the language, development methodology, and individual engineer, and are often used for a discrete task, like a debugger or profiler. Tools may be discrete programs, executed separately – often from the command line – or may be parts of a single large program, called an integrated development environment (IDE). In many cases, particularly for simpler use, simple ad hoc techniques are used instead of a tool, such as print debugging instead of using a debugger, manual timing (of overall program or section of code) instead of a profiler, or tracking bugs in a text file or spreadsheet instead of a bug tracking system.

Tool (song)

"Tool" is a 7" single by Baboon that was released in 1993 on Silver Girl Records. Side A is 33rpm while side B is 45rpm.

The song "Tool" also appears on the band's first album, Face Down in Turpentine, though the album version is a different recording. The recording of "Tool" from this single also appears on the Get It Through Your Thick Skull compilation.

This version of the first b-side ("Why'd You Say Die?") is also on Face Down in Turpentine and Baboon's 1996 The Numb E.P..
