What machining operation specifically creates square, round, or rectangular pockets in a material?

Pocket milling is a specific machining operation designed to create pockets of various shapes such as square, round, or rectangular within a material. This process involves the use of a milling machine equipped with a rotary cutter, which systematically removes material to form the desired cavity or pocket.

The versatility of pocket milling allows for precise control over the dimensions and depths of the pockets, making it suitable for applications that require complex shapes or features in various materials. Its ability to create flat bottomed pockets helps in achieving a specific design requirement that other operations may not effectively address.

In contrast, options like turning primarily involve rotating the workpiece against a tool to create cylindrical shapes, while drilling focuses on creating holes but does not typically form pockets. Cutting is a broader term that encompasses various methods of material removal but lacks the specificity of pocket milling in terms of creating defined recesses in a workpiece.
