To further increase the credibility of the concept we wish to start the semester by drilling in a prostate.
To do this we need permission from Sebastian, Øystein needs vaccinations, and the prototype must be ready for it.
Finishing the prototype
The collett nut turned out not crooked after all. We simply installed it wrong. To install it right one first snaps the collet into the nut and then insert it into the CNC. Only then can you insert the mill bit and tighten.
Before testing can commence some improvements must be done to the prototype. We have to make sure that the sanitation aspect of the prototype is of high enough quality.
Our primary idea is to design a filter adapter for to attach to the tube sucking air out of the vacuum. This would stop biohazard material from entering the vacuum causing further contaminations.
If this was to work as intended, we would be ready for testing.
Our assessment of the filter requirements are as follows:
The particle size should not differ much from the spoon created by milling other materials.
"THE MEASUREMENT AND DISTRIBUTION OF WOOD DUST" says that wood dust diameter is normally in the range 30 µm to 10 µm, but with thin processing can be as small as 5 µm.
The difference is that we would now be handling biohazardous material, which is more dangerous than wood dust, so the safety margin for how much dust should be allowed to pass is probably not strict enough. This we must research further.
We will probably need to learn what the industry standard filter for prostate tissue is, as that is what we will need for the final prototype.
Sebastian
Sebastian will try to get the permissions.
As extra safety measures the test should be conducted down at the MR Core Labs and be performed by one of the scientists there.
We are meeting with him 12:30 to discuss the plan.
