Access tool table

Press TOOL TABLE key and navigate to the countersinking tool entries to verify tool parameters.

Use the search function in tool table by pressing GOTO and entering the tool number

Check tool angle parameter

Verify the ANGLE column in tool table matches the required countersinking angle from your program (typically 60°, 82°, 90°, or 120°).

Ensure the angle is entered as a positive value in degrees

Correct tool geometry

Edit the tool table entry and input the correct countersinking angle value, then press ENT to confirm changes.

Use machine parameter MP7440 to set default countersinking angle tolerance if frequently encountering this issue

Reload tool data

Execute TOOL CALL for the corrected tool or restart the program block to refresh AWG optimization.

Use TOOL DEF to redefine tool parameters directly in the program if tool table access is restricted

Verify tool type definition

In TOOL TABLE, check that countersinking tools have TYPE field set to 205 (countersinking tool) in the tool definition.

Tool types are critical for AWG recognition - type 205 specifically identifies countersinking tools

Check tool status

Ensure the STAT (status) column shows the tool as active and not locked (L) or replaced (R).

Locked tools will not be considered by AWG optimization

Define missing tools

Add new tool entries with proper countersinking tool parameters including diameter, angle, and cutting length using TOOL DEF or tool table input.

Copy existing similar tool entries and modify parameters to save time

Activate tool management

If using tool management, ensure tools are properly loaded and recognized in the tool magazine through TOOL MANAGEMENT menu.

Use machine parameter MP7266 to enable/disable automatic tool selection for AWG

Access AWG settings

Navigate to SETUP menu and select AUTOMATIC WORKING GEOMETRY to review optimization parameters and tolerances.

AWG settings are often found under MOD function in newer TNC controls

Check angle tolerance

Review the countersinking angle tolerance parameter and increase if too restrictive (typically ±2° to ±5° is acceptable).

Excessive tolerance may compromise machining quality

Verify diameter constraints

Check minimum and maximum diameter limits in AWG settings to ensure available tools fall within acceptable range.

Use machine parameter MP7441 to set default diameter tolerance for countersinking operations

Reset AWG optimization

Clear AWG cache and restart optimization with adjusted parameters by selecting RESET AWG in the setup menu.

Some controls require a program restart after AWG parameter changes

Review cycle parameters

Check the countersinking cycle (typically CYCLE 240 or similar) for correct angle parameter syntax and values.

Incorrect cycle parameters can damage workpiece or tooling

Validate angle specification

Ensure the countersinking angle is specified correctly in the cycle call, matching available tool angles in the tool table.

Use F1 help key while in cycle definition to see correct parameter format

Check diameter specification

Verify that the programmed countersinking diameter is achievable with available tools and within machine limits.

Use simulation mode to verify cycle parameters before actual machining

Test cycle syntax

Run program in simulation mode or single block to verify cycle executes without parameter errors.
