Fundamentals

  • The control uses process monitoring to detect disturbances in the machining process, e.g:.
  • Tool breakage
  • Incorrect or missing workpiece pre-machining
  • Changed position or size of the workpiece blank
  • Wrong material, e.g. aluminum instead of steel

Process monitoring allows you to monitor the machining process during program run using monitoring tasks. The monitoring task compares the signal curve of the current execution of an NC program with one or more reference machining operations. The monitoring task uses these reference machining operations to determine an upper and lower limit. If the current machining operation is outside the limits for a predefined hold time, the monitoring task executes a defined response. If, for example, the spindle current drops due to a tool breakage, the monitoring task executes a predefined response.
