Common Causes

• Programmed lead value does not match the actual physical lead of the installed tap
• Tap geometry data in tool offset table is incorrect or incomplete
• Spindle speed calculation resulted in a lead incompatible with machine capabilities
• Tool changer or spindle orientation failed, resulting in wrong tap being selected
• Conflicting lead specifications between NC program and tool database

Troubleshooting Steps

1. 1Verify the tap specification in the NC program matches the physical tap installed in the spindle, including lead pitch and direction of rotation
2. 2Check the tool offset table (offsets, geometry data) for the selected tool and confirm lead values are correctly entered
3. 3Review the spindle speed and feed rate calculations in the active tapping cycle; ensure the computed lead is physically achievable on the machine
4. 4Inspect the tool changer operation and spindle orientation function to confirm the correct tool was selected and positioned
5. 5Compare programmed lead parameters against machine documentation and tap manufacturer specifications to identify discrepancies
