Tool Setter

Definition

Device used to measure tool length or diameter.

Use the frontmatter definition as the controlled meaning for setup, machining, and inspection decisions.

Formula / Rule

• A tool setter transfers measured tool length or diameter into the offset table with repeatable reference conditions.
• Verify the setter reference surface and cleanliness before trusting offset data for production.

Typical Range

• Probe repeatability should be checked against a master tool or gauge block at regular intervals.
• Use the same contact speed and reference condition whenever offset data is compared across shifts.

Shop-floor Scenarios

• Use the tool setter before a finishing tool is loaded to avoid cutting with an outdated length offset.
• Recheck a suspect tool on the setter when surface finish changes without a matching program change.

Common Errors / Troubleshooting

• If offset repeatability is poor, clean the contact surface and verify setter probe repeatability with a master tool.
• If measured length changes unexpectedly between checks, inspect spindle taper cleanliness and tool clamping condition.
