Methodology

Added value

Integration
CNC
- temperature measure
- expansion mesure
- processing
- axes correction
    Disadvantages of the « traditional »
    methodology

  • Implementation of sensors on the machine
        - Temperature sensor
        - Expansion sensor on the spindle

  • Based on the measures
        -> compensations by the CNC

  • Model of knowledge
        - Based on physical parameters
        - Very approximate compared to reality
        - It does not deal with the source of the
          problem, but on measuring the effects
        - Relations between cause and effect
          difficult to establish and incomplete
    Drawbacks
  • Complexity
  • Incomplete
  • High cost
