This can include CNC controls and software integration, which are less common in traditional machines. 6. **Operator Skill Level**: Operating a combination machine may require a higher skill level due to its complexity and the integration of various functions, whereas traditional machines might be simpler to operate but require multiple operators for different tasks. 7. **Flexibility and Customization**: Combination machines offer greater flexibility in handling a variety of tasks and materials, often allowing for customization of operations to meet specific production needs, unlike traditional machines which are typically designed for specific tasks. 8. **Production Speed**: The ability to perform multiple operations in a single setup can significantly increase production speed, making combination machines ideal for high-volume or complex production environments.

Combination machines for sheet metal can perform a variety of forming actions, including: 1. **Bending**: This involves deforming the metal along a straight axis to create angles or curves. Press brakes and folding machines are commonly used for this purpose. 2. **Cutting**: Combination machines often include shearing capabilities to cut sheet metal into desired shapes and sizes. This can be done using guillotines or laser cutting attachments. 3. **Punching**: These machines can punch holes or create patterns in sheet metal using a punch and die set. Turret punch presses are a common example. 4. **Rolling**: Sheet metal can be passed through rollers to create cylindrical shapes or curves. This is often used for making pipes or rounded components. 5. **Stamping**: This process involves pressing a die into the sheet metal to create raised or recessed designs, often used for decorative purposes or to add structural features. 6. **Embossing**: Similar to stamping, embossing creates raised designs on the sheet metal surface, often for aesthetic or functional purposes. 7. **Notching**: This involves cutting out sections from the edges or corners of the sheet metal, often to allow for bending or joining. 8. **Forming**: This is a broad category that includes any process that changes the shape of the metal without removing material, such as deep drawing or hydroforming. 9. **Beading**: This process adds a bead or ridge to the sheet metal, often for reinforcement or decorative purposes. 10. **Seaming**: Used to join two pieces of sheet metal together, often by folding or crimping the edges. Combination machines integrate multiple functions, allowing for efficient and versatile sheet metal processing in a single setup.
