- Incorrect dresser offset compensation or wear measurement parameters in CYCLE438
Troubleshooting Steps
- 1Verify the current dresser condition by visual inspection and measure actual dresser dimensions against manufacturer specifications
- 2Review the dresser limit value settings in the grinding cycle parameters and compare against the dresser tool specification sheet
- 3Check the dresser offset values and wear compensation settings in the NC program to ensure they match the installed dresser geometry
- 4If limit values are correct, replace the dresser with a new unit and reset the wear counter in CYCLE438
- 5After dresser replacement, verify the grinding wheel dressing operation completes successfully and monitor for alarm recurrence
