Jig and Fixture Design - Principles PRINCIPLES OF JIG DESIGN Jigs and fixtures may be defined as devices used in the manufacture of duplicate parts of machines and intended to make possible interchangeable work at a reduced cost, as compared with the cost of producing each machine detail individually. Jigs and fixtures serve the purpose of holding and properly locat- ing a piece of work while Jigs and Fixture - LinkedIn SlideShare 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 The jig and fixture design procedure - SlideShare 2. Steps in Fixture Design Procedure 1. Locating 2. Clamping 3. Supporting 4. Applying cutter guides 5. Drawing the fixture outline as an envelop that combines all the previously drawn elements. In practice, one operates continuously with the part and hence the part outline should be drawn either in thin lines or in coloured lines. 3. Locating and Degree of Freedom • The forces acting UNIT 4 DESIGN OF FIXTURE Design of Fixture

A Fixture is a special workholding device that holds work during machining or The classical design of a workholder (e.g., a drill jig) involves the following steps: The 3-2-1 location principle is used to ensure that every part placed in the Chapter I: Introduction to Fixture Design. 3. 1.1.2 Importance of Fixtures in One of the principal purposes of a machining fixture is to locate the workpiece. Computer Aided Fixture Design (CAFD) tools and methods. constraint in definition (1) is incorporated based on 3-2-1 principle, a principle for secure location reconfigurable fixture, it has to satisfy the following general design principles. •. 3- 2-1 locating principle. •. Supporting pins should be as far apart as possible. IEEE Journal of Robotics and Automation, RA-1 (2) (1985), pp. 3. J.R. Boerma, J.J. Kals“Fixture Design with FIXES: the Automatic Selection of Positioning. 25 Jul 2003 detailed descriptions of theoretical fixture design principles (a power point The location of box-type parts is usually achieved using the 3-2-1. bring one each bush directly under the drill. 2. Fixtures should be securely clamped to the table of the machine upon which the work is done. Page 9. JIGS. FIXTURES. 3. The jigs are special tools particularly in drilling, reaming Fundamental principles of Jigs FOOL PROOF: The design of jigs and fixtures should be such.

(HPACs), which have a discharge pressure above 1,000 psi They can also be classified according to the design and principle of operation: 1. Rotary Screw compressors 2. Turbo or Axial Compressors. 23. There are other design types of compressors also, but the general type is given above. These are also differentiated on the
Jig and Fixture White Paper - Applied Engineering Applied Engineering Inc Created 2/3/09 by Natalie Schroeder 1 Jig and Fixture Design General Information All six degrees of freedom, along X, Y, and Z axis, both laterally and rotationally, need be constrained for a part to be fully located. Two basic locating principles are 3-2-1 locating and 4-2-1 locating. The first, 3-2-1 locating, is the minimum requirement for location.
