How to Set Tool's Cutting Depth for CNC Oscillating Knife Cutting Machine
To get the perfect cutting depth for an oscillating knife cutting machine, first place a piece of A4 paper under the tool, and when it cuts right through, we have completed the first setup. Next, we need to cutting tests on the materials and fine-tune the knife depth according to the cutting effect. Only in this way can we obtain the best knife depth data and perfectly cut through the material without damaging the work platform.

Hello everyone, I’m John from AMOR CNC.
I’ll guide you through the correct procedure for setting the cutting depth of a tool, ensuring precision in every cut.

7 Problems Caused by Wrong Setting of Oscillating Knife Cutting Depth

Incomplete Cuts: If the cutting depth is set too shallow, the blade may not fully penetrate the material. This results in parts that are not completely cut out, requiring additional manual effort to separate them, which can compromise the precision and efficiency of the production process.

Material Damage: Setting the depth too deep can lead to the blade cutting through the material and into the cutting mat or the machine bed itself. This not only damages these surfaces, requiring costly repairs or replacements but also risks compromising the integrity of the cut material.

Reduced Tool Life: An excessively deep cut puts unnecessary stress on the cutting tool, leading to premature wear and tear. This means the tools will need to be replaced more frequently, increasing operating costs.

Decreased Quality and Accuracy: Incorrect cutting depth can adversely affect the quality of the cut edges, leading to poor finish quality or inaccuracies in the final product. This is especially critical in industries where precision is paramount.

Increased Material Waste: Both too-shallow and too-deep cuts can lead to increased material waste. In the case of shallow cuts, materials may not be fully utilized due to the need for re-cuts. With deep cuts, damage to the material from excessive cutting can render parts unusable.

Operational Efficiency Loss: Time is lost adjusting and re-adjusting the machine for correct cutting depth, leading to decreased operational efficiency and increased production times.

Safety Risks: Incorrectly setting the cutting depth, especially if set too deep, can increase the risk of blade breakage or machine malfunction, posing safety risks to operators.

In essence, getting the cutting depth just right is like finding the perfect water temperature for a Goldilocks bath – not too hot, not too cold, but just right. It ensures your materials are cut precisely, your tools last longer, and your products meet the quality your customers expect, all while keeping your machine from accidentally becoming an amateur sculptor.

How to Set the Correct Cut Depth for an Oscillating Knife Tool

First, we need to install the blade on our machine. This is a crucial step for achieving the perfect cut. How to properly install blades, you can view “How to Properly Install Blades for Oscillating Knife Cutting Tools”

Next, we’ll use a piece of A4 paper, placing it on the machine’s work surface. This simple tool will help us gauge the cutting depth accurately.
On the operation panel, click ‘Adjust’ to call up the operation number for the vibrating knife, which is SP4 in this case.
Then, click ‘Cut’ to make the tool oscillate.
We’ll set the tool drop range to 5mm to start.
Press the lower button multiple times, closely observing the distance between the blade and the paper.

How to Set the Correct Cut Depth for an Oscillating Knife Tool

Reduce the blade’s descent as it approaches the paper. Click the drop button again until the blade just touches the paper.

When dragging the paper and it gets scratched, that means the knife depth is just right.
Click ‘√’ to save the data.
With that, we’ve successfully set the cutting depth of the tool.
Now, we need cut the actual material to check if the knife depth is reasonable.

How to Fine-tune the Cutting Depth of an Oscillating Knife Tool

After testing, if we find that the material can be cut through, but it has hanging residue, it cannot be cut through perfectly. We need to increase the depth of the cutter’s cut:
Click “Adjust” and set the decrease amplitude to 0.1. Click “+” 5 times to increase the knife depth by 0.5mm.

Fine-tune the Cutting Depth of an Oscillating Knife Tool

If we find that the material can be cut through but the felt is damaged, this is not allowed.
We need to reduce the depth of the cutter’s cut:
Click “Adjust” and set the rising amplitude to 0.1. Click “➖” 5 times to reduce the knife depth by 0.5mm.

Let’s cut and test again. And adjust according to the test results until the optimal cutting depth is obtained. This may need to be repeated several times, please be patient.

This demonstration shows how to correctly set the cutting depth of the tool.

Have you learned how to set the cutting depth accurately? With practice, you’ll ensure precision in every cut. Thank you for watching. For more tips and tutorials, keep following AMOR CNC.
