Step 7 of 7
  Next unit: Evaluation of the coordinate measurement

• In this unit, you have learnt ...
  • what a part coordinate system is (and how it differs from the machine coordinate system)
      
  • how the alignment works
      
  • how datums are determined and why the order of datums is important
       
  • what datums look like in a more unusual case
       
  • what to bear in mind during the measurement
       
  • what effect the number of probing points and their distribution have on the measuring result
        
• Now you will learn why during the measurement it is so important to be aware of the risks of collision and of shaft probing:
    
  • Because any shaft probing will completely falsify the measuring result and
    
  • In case of collision there may be a slight bending and therefore the styli have to be requalified.
       
• Finally, there is also a questionnaire to fill out.
