![](../images/hardware/planktoscope_case_00.png)
[CNC (computer numerical control) milling machines](https://en.wikipedia.org/wiki/Numerical_control) are used to fabricate parts with precise dimensions and shapes. The configuration of the feed rate and diameter plays a crucial role in the machining process and can significantly affect the quality and efficiency of the production of a workpiece.

### Tools
* CNC Milling machine with a minimum traverse path at a minimum size of 600 mm to 1000 mm
* End Mill Ø 6mm
* End Mill Ø 3mm
* End Mill Ø 2mm
* End Mill Ø 1mm

### Material
#### Wood
[Valchromat](https://www.investwood.pt/de/valchromat/) is a wood-based composite material made from recycled wood fibers and colored with natural dyes. It is known for its durability, resistance to moisture and decay, and ability to be machined and finished in a similar way to solid wood. Here are some of the key characteristics of valchromat:
* Durability: Valchromat is a highly durable material that is resistant to moisture, decay, and termites, making it ideal for use in outdoor or high-moisture environments.
* Strength: Valchromat has a high mechanical strength, making it suitable for use in structural applications such as flooring, furniture, and doors.
* Machinability: Valchromat can be machined using traditional woodworking tools, such as saws, routers, and drill bits. It can also be finished using sanding, staining, and painting techniques.
* Sustainability: Valchromat is made from recycled wood fibers, which makes it a more sustainable option compared to traditional wood products. It is also produced using an eco-friendly manufacturing process that generates zero emissions.
* Versatility: Valchromat is available in a variety of colors, including shades of red, yellow, green, blue, and black, making it suitable for a wide range of applications and design projects.

* When compared to conventional MDF wood, valchromat has a number of advantages. It is more durable and resistant to moisture and decay, making it a better choice for use in outdoor or high-moisture environments. Valchromat is also more sustainable, as it is made from recycled wood fibers.
* Valchromat can be processed using a CNC router in a similar way to MDF wood. However, it is important to consider the specific characteristics of valchromat when setting up the CNC router, such as the appropriate cutting speed and feed rate.
For the specific use case of the PlanktoScope Case, valchromat was used with a **thickness of 8mm**. This thickness may be suitable for a variety of applications, depending on the specific requirements and design of the project.
In summary, valchromat is a durable, strong, and versatile wood-based composite material that can be machined and finished in a similar way to solid wood. It is available in a variety of colors and is a more sustainable alternative to traditional wood products. When processed using a CNC router, it is important to consider the specific characteristics of valchromat in order to achieve the desired results.
#### Finishing
[Rubio Monocoat Plus](https://www.rubiomonocoat.com/) is a wood finishing product that is designed to provide a durable, natural-looking finish to wood surfaces. It is made from plant-based oils and pigments, which give it a unique, transparent finish that enhances the natural beauty of the wood.
One of the key features of Rubio Monocoat Plus is its versatility and ease of use. It can be applied to a wide range of wood species, including hardwoods and softwoods, and can be used on both indoor and outdoor surfaces. It is also easy to apply, with a simple one-coat application process that allows users to achieve a professional-grade finish in a matter of hours.
Rubio Monocoat Plus is also environmentally friendly, with a low VOC (volatile organic compound) content and a biodegradable formula. This makes it a popular choice for those who are looking for a sustainable and eco-friendly wood finishing solution.
We use Rubio Monocoat Plus as a finishing product for Valchromat.
### Workflow
Here is a step-by-step guide on how to configure the feed rate and the diameter of the end mill of a CNC milling machine for the production of a workpiece, using the specified tools and configuration:
1. Select the appropriate end mill: The end mill should be selected based on the material and shape of the workpiece, as well as the desired level of precision. For this specific production, the following end mills will be used:
* 6mm end mill for straight flats
* 2mm end mill for inner contours
* 1mm end mill for small holes
2. Determine the feed rate: The feed rate is the speed at which the end mill moves along the surface of the workpiece and is usually measured in millimeters per minute (mm/m). The appropriate feed rate will depend on the diameter of the end mill and the material and thickness of the workpiece. For this specific production, the following feed rates will be used:
* 1500mm/min for 1-2mm end mills
* 2500mm/min for 3mm end mills
* 3500mm/min for 6mm end mills
3. Load the end mill: Once the appropriate end mill has been selected, it can be loaded onto the spindle of the CNC milling machine.
4. Set the workpiece: The workpiece should be securely clamped onto the table of the CNC milling machine.
5. Set the machine parameters: The feed rate and end mill diameter should be entered into the machine's control panel or included in the machining program.
6. Begin machining: The machining process should be carried out in the following sequence:
* Mill the screw holes with a 2mm end mill and then with a 3mm end mill
* Mill the corners with a 2mm end mill
* Mill everything else with a 3mm end mill
By following these steps, you can properly configure the feed rate and the diameter of the end mill of a CNC milling machine for the production of a workpiece. It is important to follow the manufacturer's recommendations and guidelines for the specific CNC milling machine being used, as well as to use proper safety measures while operating the machine.
