CNC Turning Milling Compound Processing


CNC turning milling compound processing, also known as multitasking machining, combines the capabilities of CNC turning and CNC milling in a single machine. This allows for the simultaneous or sequential execution of turning and milling operations on a workpiece. The process involves the use of a CNC turning milling center, which integrates both turning and milling capabilities. Here is an overview of CNC turning milling compound processing:

1. Workpiece Setup: The workpiece is secured in the machine's chuck or collet, allowing it to rotate for turning operations. The machine may also have additional tooling or fixtures to support the workpiece during milling operations.

2. Turning Operations: The machine starts with turning operations, where the workpiece rotates, and a cutting tool removes material from the surface. This can involve facing, taper turning, contouring, threading, or other turning operations.

3. Milling Operations: Once the turning operations are complete, the machine transitions to milling operations. This involves using a milling tool, typically mounted on a tool turret, to cut and shape the workpiece. Milling operations can include drilling, slotting, contouring, pocketing, or surface milling.

4. Tool Changes and Transitions: Depending on the complexity of the part and the required operations, the machine may perform tool changes during the process. This allows for the use of different turning and milling tools to perform various operations. The machine also transitions between turning and milling operations as needed to achieve the desired geometry and surface finish.

5. Machining Parameters and Control: Throughout the process, the machine controls various parameters such as spindle speed, feed rate, tool positioning, and coolant flow. These parameters are carefully adjusted to optimize cutting conditions, tool life, and surface quality.

6. Finishing Operations: After the primary turning and milling operations, additional finishing operations may be performed. These can include chamfering, deburring, or polishing to improve the part's aesthetics and functional characteristics.

7. Inspection and Quality Control: Once the compound processing is complete, the finished part is inspected to ensure it meets the required specifications. This can involve visual inspection, measurement with precision tools, or advanced inspection techniques.

CNC turning milling compound processing offers advantages such as reduced setup time, increased productivity, and improved accuracy compared to performing turning and milling operations separately. It is commonly used for complex parts that require both turning and milling operations in industries such as aerospace, automotive, and medical equipment manufacturing.

It's important to note that the specific steps and parameters of CNC turning milling compound processing can vary depending on the machine, workpiece, and desired outcome. The machine's capabilities and the programming software play a significant role in determining the process parameters and tooling configurations.
