ver the
past three to four decades industry in the United States has been affected by
intense global competition from industries using the latest technologies in
their manufacturing methods. Superabrasive tooling, designed to increase
productivity, produce better quality products, and reduce manufacturing costs,
can cut and grind the hardest materials known.
The
fundamental cutting processes in machining - those of bringing the work into
contact with the cutting tool - should remain mainstays of the industry. One of
the most important components in the machining process is the cutting tool and
its performance determines the efficiency of the operation. Modern tooling
systems that can accommodate increased spindle speeds, higher feed rates,
increased radial loads, modular adaptability, and profitable short part runs
are required by manufacturers to stay competitive.

Worldwide
manufacturing markets require tooling systems that combine high accuracy,
consistent repeatability, quickchange qualities, and high-pressure coolant capability.
Modern tooling systems that can accommodate increased spindle speeds, higher
feed rates, increased radial loads, modular adaptability, and profitable short
part runs are required by manufacturers to stay competitive.
Modular
tooling systems are made up of a number of components (modules) that are used
in a variety of ways to meet the requirements of specific job applications.
Modular tooling is a complete tooling system that provides versatility and the
flexibility to assemble the combination of cutting tools and holders necessary
to manufacture a part, Fig. 3-3-1. A modular tooling system must have rigidity,
accuracy, and quick-change capability; this provides an effective tooling
system that is the basis for increased productivity.

Modular
tooling systems eliminate the cost of maintaining a large tool inventory. These
systems include a basic clamping (holding) unit mounted in a spindle or turret
that holds a variety of cutting units, or cutting tool carriers. The cutting
units consist of adapters, extensions, toolholders, and inserts that can be
assembled to perform a wide range of milling, drilling, boring, and turning
operations.
