After acquiring a plasma cutter at the space, it seemed only logical to try and fabricate a CNC version eventually.
This goal is still a while away for now, but as always, we are full of Ideas and this is a convenient place to put them.
Specs
- 3x3 m working area
- movement speed of 1000mm/s
- Calibrated accuracy and precision of +/- 0.1mm
Axis motors
smeding is going to design and build a proof of concept linear (synchronous) motor for use in the X- and Y-axes. This test rig will be used to determine whether a DIY LSM is at all useful for our application and to finalize the design if we choose to go with the concept. Specifically, this involves figuring out:
- How the attainable accuracy compares to the wanted specifications
- How the attainable movement speed compares to the wanted specifications
- A final design for the drive electronics
- Coil and armature geometries
- Rail geometries (magnet size, spacing and orientation pattern and any backing)
- Optimal control schemes
After this, we'll be ready to construct the three rails (2x X and 1x Y) that make up the bulk of the CNC machine.
