23 February 2017
Status
new straight knife and cutting wheel
vacuum tightness much better
wheel at 2mm depth
attack angle existent (?)
first dummy module successfully cut!
Links
ToDo:
- test new flipper
- cut second dummy module (all)
- do environmental effects (Marco, GS)
- start listing possible issues for "Service Manual"
20 February 2017
Status
straight knife measured to be bent with deviations up to 20 microns
cutting wheel quite possibly damaged
attempted cutting of module with silicon removed showed that the module is not immobile during cutting
movement in 10s of microns while cutting observed (could be solved with new/better knife and wheel)
Discussed
status after last weeks cutting
immediate steps needed for next cutting
update on sensors for the transport box
ToDo:
- repair knife and wheel (Gerrit)
- measure friction due to vacuum (Marco, GS)
- try to remove 2 silicon chips for future cutting simulations (GS)
- measure module movement with deeper wheel bite and/or smaller cut angle (Paul, GS)
- decide on the position of the sensors in the transport box (Paul, Marco)
- install sensors (carpenter?)
- measure environmental effects and shock on the transport box (Marco, GS)
