1. Define the term Tool design. Tool design is the process of designing and developing the tools, methods, and techniques necessary to improve manufacturing efficiency and productivity. 2. Name the various operations that can be performed using Jig and Fixture. Jig is usually lighter in construction. Jigs are used on drilling, reaming, tapping
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. An example of a jig is when a key is duplicated, the original is used as a jig so the new key can have the same path as the old one.
Plate jig‐‐The jig plate is clamped over the work piece. Swinging leaf jig‐‐The jig plate containing the bushing is swung about a pin, just for easy placement and withdrawal of the component. Indexing jig uses an indexing plate to dill holes in pre‐defined angular positions.
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. It provides equilibrium but not

Figure 4-1. The three basic forms of tool-body construction are cast, welded, and built up. Cast tool bodies are made in a variety of styles and types. The most common casting materials for tool bodies include cast iron, cast aluminum, and cast magnesium. Cast materials occasionally found in specialized elements for tool bodies, rather than in comp...
Tooling plates are standard, commercially available base elements used to construct a variety of different workholders. Like other fixturing elements, these plates come in several variations to meet most fixturing requirements. Rectangular Tooling Plates: Of all standard tooling plates, the rectangular ones, Figure 4-2, are the most popular. Their ...
Tooling blocks are often used on horizontal machining centers. The most-common tooling blocks are the two-sided and four-sided styles. These blocks work both for mounting workpieces directly, or for mounting other workholders. All working faces are accurately finish mac hined to tight tolerances, and qualified to the base. Dual mounting capability,...
Precision cast sections come in a variety of shapes and sizes. Most cast sections are available in standard lengths of 25.00”, and all sizes and styles are available in precut 6” lengths, with squareness and parallelism within .005”/foot on all working surfaces. The sections can also be ordered cut to any specified length. The two common cast-secti...
Angle brackets are often used when a right-angle alignment or reference is required. Although angle brackets are commonly thought of as 90º elements, there are also adjustable-angle styles of angle brackets and plates. Plain Angle Brackets. The plain angle bracket, Figure 4-26, is available with or without locating holes. Angle brackets are often u...
Hoist rings should, for safety reasons, be added to any tool weighing over 30 pounds. The following are design considerations when selecting hoist rings. Hoist-Ring Safety Precautions. Simply following a few basic safety precautions makes working with hoist rings both safer and more efficient. 1. The load on each hoist ring is not simply total weig...
Threaded inserts are widely used for construction and repair of workholders. The most common use for the inserts is to reinforce threads in new workholders or to repair threads in existing workholders. Threaded inserts provide a way to strengthen threaded holes in new workholders where repeated use may cause excessive wear, such as with aluminum or...
Some of the terms commonly used to refer to our products include "jigs" and fixtures." Often, these terms are confused and used interchangeably. However, there are distinctions between jigs and fixtures. Although many people have their own definitions for a jig or fixture, there is one universal distinction between the two.
