We need to control tool calibration. What system prevents a machine from running if the tooling is past its expiration date?

A system that actively blocks a machine or process from running when a tool, gauge, or instrument is past its expiration or calibration date is generally referred to as an Automated Calibration Lockout or Interlocked Calibration Management System (often integrated within Tool Crib Management, MES (Manufacturing Execution Systems) , or QMS (Quality Management Systems)).

Depending on how deeply integrated your factory floor is, this functionality is achieved through a combination of systems:

• Tool Management & Presetting Software: Advanced tool crib software (such as Zoller, CribMaster, or WinTool) tracks individual tool assemblies, serial numbers, and calibration/life cycles. When integrated with the machine controller or DNC (Distributed Numerical Control) network, the software flags an expired tool and refuses to load the tool offset or program into the CNC machine.
• MES / MOM Integration (Manufacturing Execution / Operations Management): Systems like Rockwell FactoryTalk, Apriso, or Siemens Opcenter track the shop-floor routing. Before a work order can start, the MES requires the operator to scan the tool or barcode. If the database shows the calibration status as expired or "out of tolerance," the MES holds the recipe/program and prevents the PLC or machine from executing the cycle.
• PLC/CNC Hard Interlocks (Gauging & Inspection): In automated or inline inspection cells, a hard interlock is programmed into the Programmable Logic Controller (PLC). If a calibration check (like a master gauge block or calibration cycle) isn't performed or passes its time window, the PLC drops the safety/run permissive signal, physically preventing cycle start.

If you want to set this up or troubleshoot an existing architecture, let me know:

• What CNC control or machine brand are you using (Fanuc, Siemens, Haas, etc.)?
• Are you looking for a software-level block (via an MES/ERP) or a direct machine-level interlock?

The general control is a calibration/tool-life interlock (often implemented through a tool-management or MES/PLC system).

It typically works like this:

• Each tool has a unique ID and a calibration/expiration date in the system.
• Before a machine cycle or job can start, the control system checks the tool's status.
• If the calibration has expired, the tool is marked out of calibration/quarantined and the machine or job is prevented from running.
• A valid recalibration/release is required to clear the interlock.
• The system should also retain an audit trail of the expiration, block, and subsequent release.

This is stronger than merely displaying an overdue warning. Tool-management systems can prevent an expired tool from being issued, while integrated manufacturing systems can block the production task itself.IFS Documentation+2

If you mean a CNC machine specifically, the relevant mechanism is usually called a tool-life/calibration interlock, implemented in the CNC/PLC/MES control.

The system you’re looking for is generally called a Tool Life Management System (or Tool Management System). In CNC and automated manufacturing, it tracks tool usage, expiration limits, and calibration/status data, and can prevent a machine cycle from starting or continuing when a tool is no longer valid.Heidenhain+1

Depending on the type of “expiration” you mean:

• Cutting tool life expiration (wear/use limit): A CNC controller’s tool life management function tracks time in service, number of parts produced, or wear limits. When the limit is reached, the tool can be marked disabled, a replacement tool can be called, or the machine can stop.Siemens Industry Support+1
• Calibration expiration (inspection/calibration due date): A tool control / calibration management system is typically used. It maintains calibration records, due dates, and tool status; production systems can be configured to block use of overdue tooling until it is recalibrated.Coplan / KIT
• Automated manufacturing enforcement: Integration between the tool database, CNC controller, PLC, and shop-floor tool management software creates the “lockout” behavior—only tools with an acceptable status are allowed into production.Caron Engineering

Common names you may hear:

• Tool Life Management (TLM)
• Tool Management System (TMS)
• Tool Control System
• Calibration Management System
• Gage Management System (for measurement tools)

If you mean calibrated inspection tools (torque wrenches, gauges, CMM probes, etc.) rather than machining cutters, the answer is usually a Calibration Management System with tool-status lockout.

The system is typically called a calibration management system with calibration lockout (or calibration due-date lockout). It tracks each tool’s calibration status and prevents use when the tool is past its expiration date.Simple Manufacturing+1

Common implementations include:

• Tool management software / CMMS integration — marks expired tools as unavailable and blocks checkout or assignment.Oxmaint
• Smart tool cribs or automated dispensing systems — physically prevent an operator from retrieving an expired tool.Tooling Intelligence
• Machine interlocks or MES/quality-system gates — stop a production step if required tooling is not in a valid calibration state.SG Systems Global

The key control is a hard lockout, not just an alert or sticker reminder.vysix.com

The system responsible for tracking tool usage, expiration, and preventing a machine from running with expired or uncalibrated tooling is generally called a Tool Life Management (TLM) system , often integrated into a wider Manufacturing Execution System (MES) or the CNC machine’s internal control software (such as Fanuc, Siemens, or Haas control features).sgsystemsglobal.com+2

How these systems enforce compliance and prevent operation includes:

• Tool Life Monitoring / Counter: Tracks usage metrics such as total cutting time (in minutes), number of holes drilled, parts machined, or cycles completed against a preset maximum limit.youtube.com+1
• Sister Tool / Redundant Group Management: When a primary tool reaches its expiration limit, the control system automatically locks it out and swaps in a pre-calibrated "sister tool" from the same group. If no backup tool is available or if the group is fully exhausted, the system triggers an alarm and halts/prevents cycle start.emastercam.com+1
• Calibration & Expiration Lockouts: Advanced tool crib software integrated with the machine controller can tie tool assembly IDs (via RFID chips embedded in tool holders or barcode scanning) to calibration dates. If the calibration grace period lapses, the tool's status is flagged as red/expired in the database, preventing the machine or program from calling that specific tool ID.
