Holemaking Overview 271

Holemaking Overview 271 describes common holemaking operations, which are metal cutting operations that create, shape, or add features to holes. Holemaking operations may be performed with a variety of machine tools, including both manual and CNC machines. This class covers the basic principles of drilling, boring, reaming, tapping, honing, counterboring, and countersinking, and introduces specialized operations for deep hole creation. Each of these holemaking operations requires specific tooling and a knowledge of basic cutting theory. Holemaking includes some of the most common, but also some of the most complex, machining operations in the manufacturing workplace. Machinists must often perform a series of specific, precise holemaking operations to produce parts that are within tolerance. Selecting the appropriate operations and tools for holemaking, as well as understanding correct usage and best practices, is essential to ensure quality and efficient production.
