May 05, 2015· Design principles Common to Jigs and Fixtures There are some principles which are useful to design jigs and fixtures. 1: Rigidity: Jigs and fixtures should be sufficiently stiff to secure the preset accuracy of machining. 2: Fool proofing: It can be defined as “ the incorporation of design feature in the jig or fixture that will make it impossible to lead the work into jig and fixture in an

1.To avoid vibration while revolving,the fixture should be accurately balanced. 2.There should be no projections of the fixture which may cause injury to the operator. 3.The fixture should be rigid and overhang should be kept minimum possible so that there is no bending action. 4.Clamps used to fix the fixture to the lathe should be designed properly so that they dont get loosed by centrifugal force.

UNIT 6. JIGS AND FIXTURES SYLLABUS INTRODUCTION Jig: A device that holds the work and locates the path of the tool. Fixture: A device fixed to the worktable of a machine and locates the work in an exact position relative to the cutting tool JIGS Device that holds, supports, or is placed on a part to be machined. locates and holds the work piece

Jul 20, 2016· Before entering upon a discussion of the minor details of the design of jigs and fixtures, the fundamental principles of jig and fixture design will be briefly outlined. Whenever a jig is made for a compo- nent part of a machine, it is almost always required that a corre- sponding jig be made up for the place on the machine, or other part
Jig & Fixtures Principle Design Principles of Materials Science and Engineering, Mc-Graw Hill Int. Ed. ISBN: 0-07-059169-5 They are utilized for holding the work in milling, grinding, planing or turning operation. Generally all the jigs and fixtures consist of:
Fundamental principles of Jigs and Fixtures design LOCATING POINTS: Good facilities should be provided for locating the work. The article to be machined must be easily inserted and quickly taken out from the jig so that no time is wasted in placing the workpiece in position to perform operations.
The principle of location or the 3-2-1 principle, CAD tools (like ProE), and FEA tools (like ANSYS) are used for the design of the jigs as well as the fixtures. The jig is used for guiding the cutting tool (like a drill bit), and for doing so, jigs have components like a bush, which comes in contact with the cutting tool.
(B) machining pressure forces the work piece to the slides or based on the jig or fixture and the pressure and oil or coolant fill will cause the work to strick and difficult to remove on small jigs and fixtures,a pin located under the work will remove the part radially.
Work holding devices such as jigs and fixtures are used for holding the workpiece. Jig is workpiece holding and locating device that positions and guides or controls a cutting tool. Drill jig makes it possible to drill, ream and tap hole at faster speed and with great accuracy as compared to
Often the word jig and fixture are used in place of each other. This article will explain about the places where the jigs are used and where the fixtures are used. Also, you will come to know the differences between the jigs and the fixtures. In simple terms, a jig is a tool that guides the cutting (or machining) tool. The most common type of jig is the drill jig, which guides the drill bit
