This is a basic guideline for setting up your CAD file for Laser Cutting...........
1. Ensure your "UNITS" are set to the correct format. I doesn't matter if you operate in Metric or Imperial, just making sure its correct.
2. Please make sure if your scanning in plans and tracing them, they are sized correctly. We do not accept responsibility for providing wrong sized parts.
3. We require your Cut Lines to be RED and any Marking to be in Green.
4. "Line Style" needs to be "Continuous" and "Line Weight" to be "0.00mm".
5. You also need to factor in the width of the laser cut if you require your parts to be a snug fit. The cut width is usually 0.1mm.
6. When you've completed tracing or drawing your aircraft parts, they then need to be placed into boxes representing the size of the material required. Below is a list of sizes we supply.........
Balsa = 100mm x 915mm (Medium density)
Bass Ply = 300mm x 915mm "1.5mm & 3mm Only" (Bass Ply is the main material used in models, perfect replacement for Poplar "Lite-Ply")
Birch Ply = 300mm x 600mm "0.8, 1.5, 3, 6mm Only" (Required for structural area's only, much more expensive than Bass Ply)
We try and limit ourselves to 6.5mm Ply through the Laser. Beyond that, the material burns too much.
6. Its required to leave line gaps in 3 different areas on each part. This prevents the part falling out of the sheet, we only ship in the sheet form to prevent damage in shipping.
7. Don't forget to mark all your parts with their part number specified in the drawing. This makes identifying your different parts later on that much easier. When creating the font box, please use the font "txt" in green. If you use a graphic font, the laser goes into an engraving mode and increases the cut time enourmously!
8. When you've completed your work, please go over and double check everything. If a lot of re-work is required, I will have to return your file.
THANK YOU!
