for decades, the priorities for value chains were reliability and efficiency – a dependable supply at the lowest cost. yet now, all businesses must do more than simply deliver the product that customers want, when they want it. today’s agriculture businesses must also deliver on: a sustainable value chain through visibility and traceability.

why traceability?

traceability is the capacity to verify the history, location or status of an item. by knowing how the smallest raw materials enter and move across value chains, estates and mills are able to increase agility and effectively identify inputs and outputs to improve sustainability processes in detail.

technologies, such as ai, iot, and software platforms take traceability to the next level by tracking process status and produce movements. detailed reporting captures direct links from one touchpoint to the next.

planning vs. implementation

while businesses make plans concerning the process flow that should occur in its value chain, visibility measures how much managers know what’s actually taking place within its supply chain. this ranges from real-time insights and analysis to predictive problem solving. this know-how allows players to scale-up efforts to reduce, reuse, recycle and remanufacture.

regardless of which industry, product, or operational size, traceability drives a smarter, safer, more efficient interconnected value chain. this is the key to a more sustainable world.

interested to discover more about the capabilities of how traceability and visibility can benefit your agriculture practices?

let’s have a chat on digital tools that create circular supply chains.

Building a CNC Router
Step 4: The Z-axis assembly

So far we have looked at the first three steps in building a CNC router
Step 1: Key Design Decisions
Step 2: The Base and X-axis Frame
Step 3: The Y-axis Gantry Assembly
Now let’s look at the 4th step,

The Z-axis assembly

Below you can see two examples of Z-axis assemblies with the Y-Axis CNC Router Gantry in the background.



As with the previous discussions, when designing or building a CNC router it is important to consider the forces that are evolved. That way, you can adjust your design and verify that it will meet your design requirements . However, in order to design and build your machine to meet your requirements, you first need to understand the forces evolved.


Forces on the Z- Axis Assembly



Let’s interpret the above image.

The following explains the dimensions:

D1 = the vertical distance between the upper and lower Y-axis linear bearing rods/rails.

D2 = the vertical distance between the upper and lower sets of Z-axis linear bearings.

D3 = the length of the spindle attachment plunge arm.

D4 = the width of the Z-axis assembly.

D5 = the horizontal distance between the Z-axis linear bearing rods/rails.

D6 = the thickness of the plunge arm

D7 = the distance between the cutting force (approx, tip of the cutting tool) and 1/2 D2.

Now that we understand what the dimensions are, let’s analyze the forces and moments.


Forces and Moments on the Z-Axis Assembly
Building a CNC router can be easy or hard. Some people over analyze and some people just build it and see if it works. I think the best approach is a mix of the two methods. So let’s first try and understand what is happening.

The above image illustrates an example of a Z-axis assembly shown in a front view and a side view. Look at the front view and notice that the Z-axis assembly is moving to the right while it rides on the Y-axis linear bearing rails/rods.

The plunge arm is at max Z travel and is cutting into a material as it moves from left to right. This cutting action produces a cutting force that apposes the movement of the Z-axis assembly.

The cutting force is a variable of spindle RPMs, the number of flutes on the cutting tool, the feed rate, and the material that is being cut. You can learn more on how to calculate cutting force here . When building a CNC router an important decision to make is what types of material you would like to be able to cut, which was covered in step 1.

For now, just understand that there is a force in the opposite direction than the Z-axis assembly is moving. Now let’s see what happens because of this cutting force.

The cutting force creates a moment, which is illustrated in the image above as Moment A.

A moment is just a force that is applied at a distance. We covered moments in greater details in Step 3.

Moment A = D6 x Cutting Force.

Moment A torques the plunge arm in the opposing direction of the cutting force, which torques the whole Z-axis assembly.

br> This moment results in resultant forces that are applied to the Z-axis linear bearing rails/rods and the Z-axis linear bearings themselves. (Yellow arrows)

As D5 and D2 increase in length, the resulting forces decrease. You can see that when you are designing or building a CNC router, it is important to maximize the horizontal distance between the Z-axis linear rails rails (D5), and the vertical distance between the Z- axis linear bearing blocks.




The Plunge Arm

D2 also has an effect while cutting along the X-axis. Take a look at the image to the bellow.

The cutting force causes another moment; Moment B.

Moment B is the result of the cutting force being multiplied by the distance between the cutting force and ½ D2.

This moment will apply resulting forces on the Z-axis bearings. As the distance between these bearings (D2) increase, these forces will decrease. That is why it is best to maximize D2.

As a rule of thumb when building a CNC router, D2 should never be any less that half the length of the plunge arm. Also, you want the thickness if the plunge arm (D6) to be thick enough to not flex under your maximum cutting force.

The flex will depend on the maximum cutting force you are designing your machine around, the thickness of the material (d6), plunge arm length (D3), and the material it is made of.

If you need help calculating your desired cutting force or the amount of deformation a certain material and size will have, you may contact us We offer free design consultation and other engineering services.

Summary

Keep the following in mind when you design or build a CNC router:

Maximize D1, reduces the forces due to torque caused by the cutting force in the X-axis.

Maximize D2 reduces the forces due to torque caused by the cutting force in the X-axis.

Minimize D3, but still allow for your desired Z-axis travel.

Maximize D4, reduces the forces due to torque caused by the cutting force in the Y-axis.

Other Considerations

In later sections of the building a CNC router guide , we will discuss other features such as lead screws, motor placement, linear bearings etc.

Don’t forget that you may contact us with any questions regarding CNC machines in general or your design. We will try and help any way possible.

The motor mount that is used in the above image may be bought pre-fabricated from K2CNC.com for a variety of router spindles.
