The reciprocation of the broach always involves an un-producting return stroke, which is eliminated in a continuous surface broaching machine. In this the small workpieces are mounted on the broaching fixtures which are in turn fixed to a continuously moving conveyor. Broaches which are normally stationary, are kept above the workpieces. The workpieces are pushed past the stationary broaches by means of the conveyor for cutting. The workpieces can be loaded and unloaded onto the conveyor manually or automatically. These machines are used for mass production.

The Broaching Operation Explained
Broaching is a machining process that removes material from a workpiece by means of a tool with multiple teeth. The key distinction in broaching operations lies in how the workpiece interacts with the tool.
Types of Broaching Operations
- Pull Broaching: In this operation, the tool is pulled through the workpiece. The workpiece remains stationary, while the broaching tool moves in one direction, typically from the end of the part toward the other end.
- Push Broaching: Conversely, push broaching involves pushing the tool through the workpiece. Here, the tool moves from one end of the workpiece in a forward motion, often requiring the workpiece to be securely held in place.
- Surface Broaching: This method is specifically focused on creating flat surfaces or contours on the workpiece. It can be done in both pull and push forms, depending on the setup.
- Continuous Broaching: In continuous broaching, the workpiece moves past a stationary tool. This method allows for a continuous operation where the tool remains fixed while the workpiece is fed through, resulting in a consistent and efficient material removal process.
Why Continuous Broaching is the Correct Answer
The question specifically seeks to identify the operation where the workpiece moves while the tool remains stationary. Continuous broaching fits this description as it emphasizes the movement of the workpiece, allowing for a high production rate and enhanced efficiency in machining operations.
In summary, continuous broaching is the correct answer as it defines the operational dynamics where the workpiece travels past a fixed tool, optimizing manufacturing processes in various applications.
