UNIT 4 Clamping and Workholding Principles 47 Although standard high-strength fastening devices may be used for many workholding tasks, or locking, and other hardware should be used whenever possible, spherical washers or nuts are us. To make up for these differences. Jacks and supporting pins 2. The main points to remember in multiple clamping are that the clamping pressure must be equal on all hoffmab and that the clamp must have only one operati.
In this drill jig, the forces that cause the part to revolve are restricted and held by the locators? You can order the compilation or acquire it as soon as possible?

Lecture - 34 Design and Applications of Jigs and Fixtures
Search this site. From simple template and plate-type jigs to complex channel and box-type tooling, this newly revised edition features more than illustrations of tools and applications to spur readers to success. All-new sections on assembly tools, handling tools, and catalog reading enable readers to develop important skills. Specific examples of various jigs and commercially available fixtures also appear to guide readers in developing their understanding of how design principles, as well as the latest design and manufacturing technologies, are being applied in the construction of jigs and fixtures today. As in past editions, heavy emphasis is placed on the economics of jigs and fixtures, including methods and formulas for use in estimating workholder costs.
Other situations in which nonmechanical clamps are frequently used are where the clamping forces must be applied evenly across the entire part to minimize any possible workpiece distortion. They are either machined into the tool body Figure 3-32or installed Figure 3- Product design changes are continuously reviewed to determine tooling changes that might be necessary. For more complex parts or detailed setups, machined packing elements like those shown in Figure 4-41 can also be made to conform to the complete outer shape of the workpiece.
The reader becomes familiar with working with part drawings and production plans showing the sequencing of operations in the shop. Figure 4-47 An ElectraLock clamp. If it is held by the outer edge, the part must be supported Figure 4-2. They are usually equipped with a handle for easier movement?
