DETAILS, COMPONENTS, OR ACCESSORIES FOR MACHINE TOOLS, e.g. ARRANGEMENTS FOR COPYING OR CONTROLLING

**Definition:** This place covers:

General components that are used in any kind of machine tool, such as machine beds, feeding devices, workpiece holding means, workpiece conveying means, tool changing means, chip evacuating means, etc...

Machine configurations combining different kinds of machining operations, such as drilling, milling, turning, or cutting, e.g. sawing.

**Glossary:** - Machine tool: a mechanical working machine that removes material from a workpiece with a mechanical cutting edge to perform a shaping operation essentially through drilling, milling, turning, or cutting, e.g. sawing. The workpiece is generally made of metal, wood or plastic and is not a human body, food or cloth. - Controlling: influencing a variable in any way, e.g. changing its direction or its value (including changing it to or from zero), maintaining it constant, limiting its range of variation - Regulation: maintaining a variable automatically at a desired value or within a desired range of values. The desired value or range may be fixed, or manually varied, or may vary with time according to a predetermined "programme" or according to variation of another variable. Regulation is a form of control
