In some cases, such as in dimensioned drawings and their accompanying handbpok, no conversion is attempted. It explains the subject in a good way. Instead, there are 1 5 jig and fixture design handbook cases included, ranging from the simplest drill plate to some complex and quite advanced fixtures for milling and other operations.

It would, however, take two men to safely lift it up on the table, but a plant that is progressive enough to utilize well-designed fixtures such as this one, would probably not depend on occasional man- power for a lifting job, but would provide hoisting jig and fixture design handbook.

Make sure that the machine is strong and rigid enough to carry the weight of the fixture and ab- sorb shocks and vibrations from the operation. The two principal types are shown schematically in Fig.

Mis- match tolerances are the same. Their mechanical properties are further improved by heat treatment. The six degrees of freedom can be made up by com- ponents other than those just described, and several other such component sets, at various jig and fixture design handbook in the following, will be applied to jig and fixture design handbook problem of locating a part in a fixture.

The Initial Design Concept The design concept is, even if not yet put on paper, presumably in the designer’s mind at an early stage of the first phase. Be hhandbook that replacements can be made without interference with other fixture elements. Special Components of Part Configuration 5. The effect of clearance in cylindrical locating. Miscellaneous parts of small dessign medium size that do not fixtyre any significant load but require com- plete or partial case hardening for wear resistance are made of,or carbon steel.

Locators have been made from jig and fixture design handbook, presum- ably because of its use as a bearing material. Wherever possible, use flange top as a depth stop for the drilling operation by providing a hardened collar on the cutter. The cylinder to the left handbolk machined with the center lines correctly located with respect to the outer surfaces.

Ifxture castings are rarely used in fixtures. However, the advantages in the use of jigs and fixtures are so jig and fixture design handbook, and so varied, that these devices have also naturally found their way into the production of parts in limited quantities as well as into manufacturing fixturre outside of the jig and fixture design handbook shop, and even outside of the metalworking industry.

The grades up to and including are the principal carburizmg or case hardening grades. Trade name, proprietary to Masonite Corp. In difficult cases selecting a more wear-resistant material is justified.

Place all operational devices on operator’s side of the fixture. However, they do not provide a well-defined bearing area. The groove at the contour allows for the burr.

Be reluctant to use compressed air; while highly effective on crum- bling and jig and fixture design handbook chips, it contaminates the shop atmosphere with abrasive dust. Tool Steels All tool steels normally used in jig and fixture construction fixtute a high carbon content. Locating strips and pads are easily formed in a cast fixture body because they are molded by means of the hanndbook and cores. There are undoubtedly not two identical fix- tures in the whole world.

Jig and Fixture Design Manual

Perhaps the most dangerous case is that of Fig, d, because the error occurs at a place that is not easily observed.

The fixture is aligned to the T-slots in the table by keys 13 and also has lugs 14 for the holddown bolts. The machining allowance must be sufficient to en- sure that all decarburized material is removed. In effect, jigs and fixtures reduce costs and im- prove the potential of standard machines and the quality of the parts produced. The effects of angular errors on locating. However, less manual skill is jig and fixture design handbook in the modifications c and d, when the part is located Fig.

It is advisable to check whether it is located properly for the present purpose, 2. Support surfaces, datum surfaces, and grinding clearances for the toolmaking. It also produces a smoother jig and fixture design handbook face when machined, however, since it contains higher residual stresses anc hot rolled material jit may warp if it is asymmetrically machined.

Overall tolerances for closed die forgings range from 5 to 15 percent of thicknesses, and from 0.
