Siemens 840D 61602 - Channel block: Tool width incorrectly defined

Channel block: Tool width incorrectly defined

Plunge cutter is larger than the programmed groove width. Alarm triggered by following cycle: CYCLE93. Remedy: Check tool or change program.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Physical tool diameter exceeds the programmed groove width in the part program
  • Incorrect tool offset or tool radius compensation values entered in the tool table
  • Wrong tool loaded in the spindle compared to what the program specified
  • Program geometry does not match the actual tool width being used
  • Tool wear has increased the effective cutting diameter beyond acceptable limits

Troubleshooting Steps

  1. 1Verify the actual tool width using calipers or tool measurement device and compare against the tool table entries and program specifications
  2. 2Review the CYCLE93 call in the program at the indicated block number to confirm the programmed groove width matches design intent
  3. 3Check the tool offset register values for the active tool; correct any discrepancies in the tool radius or width compensation parameters
  4. 4Inspect the tool offset table and ensure the correct tool number is assigned with matching physical dimensions
  5. 5Run a dry cycle or simulation to verify tool clearance before resuming production; consider adjusting the program groove width or selecting a smaller tool if design allows
