What feature describes the functionality of a toolchanger in machining processes?

The functionality of a toolchanger in machining processes is primarily defined by its ability to automate the selection of cutting tools. A toolchanger is a mechanism that enables machines, such as CNC machines, to automatically switch from one tool to another without requiring manual intervention. This automation helps increase productivity by reducing downtime since the machine does not need to stop for operators to change tools manually. By allowing for quick changes between tools, the toolchanger facilitates the use of various operations in a single setup, enhancing the versatility and efficiency of machining processes.

In contrast, increasing the diameter of cutting tools, restricting the types of tools that can be used, and ensuring tools are used in a specific sequence are not inherent functionalities of a toolchanger. A toolchanger does not alter the physical dimensions of tools or limit the range of tools, nor does it necessarily dictate the order in which tools must be used; instead, it simply provides a mechanism to manage the selection and exchange of tools, which can be done in any sequence as required by the machining process.
