This project work deals with the design and fabrication of pneumatic drill jig for 0. This pneumatic drill jig shows the reduction in labor time, machining time, etc. This pneumatic drill jig is provided with pneumatic clamping arrangement.

Science Research. Abstract: The paper gave a detailed definition of jigs and fixtures, and also identified the numerous advantages that are associated with the use of jigs and fixtures in manufacturing to include: production increase, cost reduction, interchangeability and high accuracy of parts, reduction of the need for inspection and quality control expenses, reduction of accident as safety is improved, automation of machine tool to an appreciable extent, easy machining of complex and heavy components, as well as low variability in dimension which leads to consistent quality of manufactured products. The work also explained that since the design is dependent on numerous factors which are analyzed to achieve an optimum output, that jigs and fixtures should be made of rigid light materials to facilitate easy handling.

The successful running of any mass production depends upon the interchangeability to facilitate easy assembly and reduction of unit cost. Mass production methods demand a fast and easy method of positioning work for accurate operations on it.

Jigs and fixtures are production tools used to accurately manufacture duplicate and interchangeable parts. Jigs and fixtures are specially designed so that large numbers of components can be machined or assembled identically, and to ensure interchangeability of components. To eliminate marking, punching, positioning, alignments etc.

It will make easy, quick and consistently accurate locating, supporting and clamping the blank in alignment of the cutting tool. Guidance to the cutting tool like drill, reamer etc. Increase in productivity and maintain product quality consistently. It will reduce operators labour and skill requirement, Also reduce measurement and its cost.

Enhancing technological capacity of the machine tools. Reduction of overall machining cost and also increases in interchangeability. Aditya Arvind Yadav, Mr. Akshay Vilas Arekar, , Mr. Shrinath Yallapa Shirage, Mr. Mass production. Jigs and fixtures are specially designed so that large. It will make easy, quick and consistently accurate locating,. It will reduce operators. Mass production methods demand a fast and easy method of positioning work for accurate operations on itand fixtures are production tools used to accurately manufacture duplicate and interchangeable parts.

It is a work holding device that holds, locates the work piece and guides the cutting tool for a specific operation. Jigs are provided with tool guiding elements such as drill bush. These direct the tool to the correct position on the work piece. A jig is a type of tool used to control the location and motion of another tool. A jig's primary purpose is to provide repeatability, accuracy, and Interchangeability in the manufacturing of products. A device that does both functions holding the work and guiding a tool is called a jig.

The successful running of any mass production depends upon the interchangeability to facilitate easy. The details of jigs and fixtures is as given below:.

It is a work holding device that holds, supports and locates the work piece and guides the cutting tool for a specific operation.

A jig is. A device that does both functions holding the work and guiding a tool is. Fixture holds the work piece securely in the correct position with respect to the machine during operation. There is sometimes a provision with respect to the work piece, but the tool is not guided as in a jig.

Fixtures are often clamped to the machine table. It is a work holding device that holds supports and locates the work piece for a specific operation but does not guide the cutting tool. It provides only a reference surface or a device. The main purpose of a fixture is to locate and in some cases hold a work piece during either a machining operation or some other industrial process.

A jig differs from a Fixture in that it guides the tool to its correct position in addition to locating and supporting the work piece. The elements of the jigs and fixtures are as follows:.

Locating elements These position the work piece accurately with respect to the tool guiding or setting elements in the fixture. Clamping elements These hold the work piece securely in the located position during operation. Tool guiding and setting elements These aid guiding or setting of the tools in correct position with respect to the work piece.

Drill bushings guide the drills accurately to the work piece. Milling fixtures use setting pieces for correct positioning of milling cutters with respect to the work piece. Productivity Jig and fixtures eliminate individual marking, positioning and frequent checking. This reduces operation time and increase the productivity. Interchangeability - Jig and fixtures facilitate uniform quality in manufacture.

There is no need for selective assembly. Any part of the machine fit properly in to the assembly. And all similar components are interchangeable. Skill reduction - Jig and fixtures simplify locating and clamping of the work piece. Tool guiding elements ensure clamping of the work piece. There is no need for skillful setting of the work piece of tool.

Any average person can be trained to use Jig and fixtures. It saves the labour cost. The basic purposes of developing and using drilling jigs and turning fixtures for batch production in machine shops are:. Easy, quick and consistently accurate locating, supporting and clamping the blank in alignment of the cutting tool. Component- Design to be studied carefully Ensure work is performed in a proper sequence Maximum operations should be performed on a machine in single setting.

Capacity of the machine-Careful consideration to be performed on type and capacity of machine. Production requirements-Design to be made on basis of actual production requirements. Then comes decision on manual and automatic tooling arrangements. Jigs and fixture are made from a variety of materials, some of which can be hardened to resist wear. It is sometimes necessary to use nonferrous metals like phosphor bronze to reduce wear of the mating parts,.

Клушар на мгновение задумался и покачал головой: - Понятия не имею.  - Он поморщился от боли и откинулся на подушки. Беккер вздохнул.

Наверное, Испания напомнила мне о том, что по-настоящему важно. - Помогать вскрывать шифры? - Она чмокнула его в щеку.
