Hey there! Ready to dive into the exciting world of creating your very own polyester fiber dagger? Let’s get started. Don’t worry, I’ll keep things simple and straight to the point .
Materials and Tools You’ll Need
High-Density Polyester Fiber Acoustic Panel: Go for a thickness of 9-12mm. This stuff is sturdy!
CNC Oscillating Knife Cutting Machine: Make sure it has an oscillating knife tool and a bevel cutting tool. You’ll need both to get that killer blade and perfect shape.
CAD Software: To design your masterpiece.
Control Software “Xiao”: For fine-tuning and cutting control.
Safety Gear: Safety glasses and gloves – safety first, always.

Step-by-Step Guide
01. Prepare the Material:
Grab your 9-12mm thick high-density polyester fiber acoustic panel. This will be the body of your dagger.
02. Design Your Dagger:
Fire up your CAD software and get creative. Design the outline of the dagger, the blade edge, the handle, and any decorative holes you want. Imagine a mini Excalibur, but cooler.
Save your design in DXF format. This makes it compatible with our CNC machine.

03. Set Up the CNC Machine:
Load the oscillating knife tool for cutting the dagger’s outline and the decorative elements.
Load the bevel cutting tool for creating the blade edge. This tool will give your dagger that sharp, angled cut.
Secure your polyester fiber panel onto the machine’s cutting bed. You don’t want it moving around while you’re cutting.

04. Adjust the Settings:
Set the cutting parameters (speed, frequency, depth) for both tools. Each material has its sweet spot, so do a test cut on a scrap piece first.
Open Your Design in “Xiao”:
Open your DXF file in the “Xiao” software.
Assign SP operation numbers to different parts of your design:
SP5: For the blade edge, using the bevel cutting tool.
SP6: For the outline and handle holes, using the oscillating knife tool.

05. Cutting Time:
First, let’s make that blade edge sharp and fancy:
Use SP5 with the bevel cutting tool to cut a 45° angled edge.
Now, switch to SP6:
Cut out the outline of the dagger.
Add any decorative holes or elements on the handle.
06. Finishing Up:
Once all cuts are done, carefully remove your newly made dagger from the cutting bed.
Check the edges and details. Thanks to the precision of the CNC machine, there should be no need for additional sanding or finishing.
07. Show Off Your Work:
Voilà! You now have a sleek, custom-made polyester fiber dagger. Perfect for display, cosplay, or just to show off your engineering skills.

A Few Safety Tips
Always wear your safety glasses and gloves. We’re making a dagger here, not a paper plane!
Keep your work area clear and follow all safety guidelines for the machine.
There you have it! With a little bit of tech magic and some creativity, you’ve made a dagger that’s both functional and fantastic. Happy cutting!
