2-Axis Turning CAD/DFM

What is "2-Axis Turning?"

• Design for manufacturing (DFM) considerations are crucial in making parts that not only meet their functional requirements, but also can be manufactured efficiently and cost-effectively. For 2-Axis Turning, some of these considerations include:

  1. Geometry Considerations: Since 2.5 axis milling can only handle simpler geometries, complex 3D shapes may not be feasible. Designs should mainly involve features like pockets, slots, holes, and basic 2D profiles. Avoid undercuts, as these cannot be machined using a 2.5 axis setup.

  2. Tool Accessibility: Ensure that the milling tool can access all features of the design. This is particularly important for deep pockets or holes. The depth-to-width ratio of features should be appropriate to avoid long, thin tools which are prone to deflection and breakage.

  3. Material Considerations: The chosen material should be suitable for milling and take into account tool wear, cutting speeds, and finishes achievable.

  4. Wall and Floor Thickness: Thin walls and floors can lead to problems such as vibrations during milling, which can cause inaccuracies in the finished part. Walls and floors should be designed to be robust enough to withstand the milling process.

  5. Tolerances: Designs should consider the achievable tolerances of the milling machine. Overly tight tolerances can increase manufacturing time and costs significantly.

  6. Surface Finish: The desired surface finish should be considered in the design. If a very smooth surface is needed, additional post-processing steps might be required, impacting the cost and time of production.

  7. Tool Diameter: It is important to consider the smallest tool diameter that will be used, especially for interior corners. The smaller the tool diameter, the larger the internal radius will be. In 2.5 axis milling, the internal corner radius will never be perfectly sharp, but instead will be rounded to the radius of the tool.

• By keeping these considerations in mind, you can help ensure that your part can be manufactured more easily, quickly, and economically, while still meeting your necessary specifications.
