The Processing Size Error Is Too Large

Problem Description:After machining is completed, it is found that the dimensions are out of tolerance, which is common in precision shafts or mating surfaces.

Possible causes:

  • Tool compensation parameters are not entered correctly
  • Thermal expansion of the machine or thermal drift of the spindle
  • The fixture or chuck is not locked, causing vibration or deflection

Solution:

  • Set tool automatic compensation and intermediate correction
  • Use spindle temperature control system (such as oil cooling), timed shutdown and automatic zero correction
  • The first piece of each batch is inspected by three-dimensional detection to confirm the reference size
