Access tool table

Press MOD key, select 'Tool table' from machine parameters menu to view current tool definitions.

Check if dresser tool number matches the one called in your grinding cycle

Verify dresser tool entry

Locate dresser tool number in table and confirm LENGTH and RADIUS columns contain measured values, not zeros.

Never manually enter dresser dimensions without proper measurement

Perform tool measurement

Use TOOL CALL command followed by tool measurement cycle to capture dresser geometry and position relative to wheel.

Use cycle 31 TOOL MEASUREMENT for automatic dresser capture on equipped machines

Validate dresser data

Return to tool table and verify all dresser parameters are populated with non-zero values before attempting dressing cycle.

Check wheel management table

Navigate to grinding parameters and access wheel management table to verify current wheel number and associated dresser tool number.

Wheel-dresser pairs must be explicitly defined in most Heidenhain grinding applications

Verify dresser assignment

Confirm the dresser tool number in wheel management matches the actual dresser tool number in the tool table.

Mismatched tool numbers can cause collision during dressing operations

Update wheel-dresser association

Modify wheel management entry to reference correct dresser tool number, then save changes to machine parameters.

Reset grinding cycle

Clear current program state and restart grinding cycle to reload updated wheel-dresser configuration.

Backup current tool table

Export tool table data to external storage using TNC file management before making changes.

Always backup tool data before performing corrections to prevent data loss

Clear corrupted dresser entry

Delete existing dresser tool entry from tool table by setting all values to zero and confirming deletion.

Re-measure dresser tool

Perform complete dresser measurement sequence using automatic tool measurement cycle or manual touch-off procedure.

Use consistent measurement reference points to ensure repeatability

Verify data integrity

Cross-check measured values against known dresser specifications and previous measurement records for consistency.

Access machine parameters

Enter machine parameter mode using manufacturer key sequence and navigate to tool management parameters.

Incorrect machine parameter changes can disable critical machine functions

Check tool table parameters

Verify parameters for maximum tool number, tool table size, and dresser tool number ranges are correctly configured.

Review grinding-specific parameters

Examine parameters related to wheel management, dresser operation modes, and automatic tool measurement functions.

Compare current parameters with machine documentation or known good backup

Restart control system

Perform controlled shutdown and restart of TNC system to ensure parameter changes take effect properly.

Review program syntax

Examine NC program lines containing TOOL CALL commands and dressing cycle calls for correct tool number syntax.

Use TNC program editor syntax checking to identify formatting errors

Verify tool number consistency

Confirm dresser tool numbers in program match exactly with tool table entries, including any prefix or suffix characters.

Check cycle parameter syntax

Validate all parameters passed to dressing cycles match required format and value ranges specified in TNC documentation.

Incorrect cycle parameters can cause unexpected machine motion

Test program in simulation

Run program in TNC simulation mode to verify proper tool calls and cycle execution before running on machine.
