- 4 layers
- Designed in Corel Draw
- Extruded and exported to gcode from Fusion 360
- Cut with a .5mm flat end mill to allow for the detail
Slowly, over many hours
5 broken bits
Could not get the laser to cut, consistently and it didn’t seem that it would be much faster, anyway
- Camel is cut from 1/8th inch basswood ply
- The backboard and frame are made from my old birch flooring
- With the frame, it’s 13.75 inches square
Thank you for sharing this impressive work.
Given that 5 bits were broken during the work, could you please tell me the work speed?
Here is an article for your reference:
When cutting out a part with a CNC cutter, you can leave a small part as an extra clamping tool to prevent the tool from hitting the model near the end of the work, which causes the CNC bits to be broken.
I tested anywhere from 150 to about 225 mm/min. I don’t think it was the speed that was the issue. I was using a half millimeter diameter bit. Very fragile, to begin with. Then cutting out some detailed bits that were too small to accommodate tabs… I spent a lot of time watching the cut and clearing the bits of wood that were cut out. But I couldn’t watch the whole time, and I think the bits broke because of the cutouts snagging the bit. I tried using repositionable adhesive under the board, but the smaller cutouts just didn’t stick.
