This article provides a review of the research and technology trends that will shape metalcutting in the years to come. Innovations in workpiece materials, coatings, machine tool design and nontraditional machining are explored.

This article reports the results of a survey of shop owners. The survey found the executives worried about finding and retaining help and customers and keeping up with technology. It's not all gloom and doom, however. The survey also found respondents upbeat about their business and the economy in general.

Business insurance represents a costly but necessary investment for any shop. This article presents the findings of a Cutting Tool Engineering survey of the liability insurance purchasing habits of readers. The article also offers some guidelines for insurance shopping.

This article looks at the close partnership forged between a toolmaker and a machine tool manufacturer. The alliance requires the two to share detailed information about proposed products as well as the customers each is working with. Such cooperation has made it possible to develop several new products and processes.

With safety and health precautions driving up the cost of using metalworking fluids, many shops are attempting to machine dry. This article looks at the reasons why a shop might want to eliminate coolants and the effects this decision will have on part quality and tool performance.

Grinding research has led to innovations in wheels and machines, which have expanded the range of applications grinding can be used for. This article highlights some of the research being conducted and the work that has made it to the shop floor. An accompanying article discusses CBN abrasives.

Graphite electrodes are extremely difficult to machine because of the material's abrasiveness. This article explains why it takes an endmill with a CVD diamond coating and multiple flutes to cut graphite without wearing tool quickly.

Adequate flushing is needed to keep EDM wires from breaking. This article explains why wires break, and how dielectric fluid delivered with sufficient flow and pressure can prevent these failures from occurring even in less than ideal conditions.

To produce graphic electrodes for EDMing large cavities, shops sometimes must machine the piece in smaller sections and bond them together. This article explains how to build and use a bonded graphite electrode so that a ridge at the electrode's bond line can be avoided.

Centralized mineral filtration for wire-EDM dielectric fluid can remove contaminants down to the 1-micron level and dispose of them in an environmentally responsible way. This article describes the mineral filtration process and compares it to the other common filtration methods.

Tantalum and Niobium are important components in the composition of carbide tools. They are also among the most expensive. This article explores how recent trends in metalcutting and tool usage will effect the supply of these two components.

This article explains how state-of-the-art tool presetting-and-measuring machines can reduce a shop's tool setup time while increasing precision. The article also describes how the additional functions of these high-end units can turn them into sophisticated tool-management systems.
