Closed-loop gauge-to-CNC correction

TnG Offset Master

Measure the part. Apply the right correction. Keep every result traceable. Offset Master reads each gauge result, decides against your control limits and writes the correct wear offset to the FANUC CNC through FOCAS2 / Ethernet, with every decision recorded.

The problem

The offset correction gap

01

Manual interpretation

Operators must compare every value with nominal, tolerance and control limits.

02

Manual entry risk

Sign, decimal and offset-register mistakes can move the process in the wrong direction.

03

Delayed correction

During busy production, measurement and machine adjustment become disconnected.

04

Limited traceability

Paper notes cannot show the measurement, the decision and the CNC write history.

The solution

One complete correction loop

  1. Precision gauge

    Measures the component and creates the result file.

  2. CSV intake

    Watches the source folder and reads each configured parameter row.

  3. Decision engine

    Applies control limits, direction, frequency and clamp.

  4. FANUC CNC

    Writes the approved wear offset through FOCAS2 / Ethernet.

  5. Quality record

    Stores each measurement, result and correction outcome.

Features

Correction logic that respects the process

Zero offset in the green zone

Inside the control limits, a zero correction is written and a stable process is left alone.

Correction in yellow or red

The system responds only after a control limit is crossed, using the configured direction and register.

Per-parameter setup

Nominal, tolerances, control limits, direction, CSV row and CNC offset register stay with each parameter of each part.

Maximum correction clamp

Large calculated corrections are limited to the configured maximum before the write.

Offset frequency

Write after every part, or after a selected number of measured parts.

Bad-file protection

Files without an alphanumeric part number are ignored, preventing repeated invalid results.

Operator and administrator access

Operators see live results, run the CNC test and export reports. Setup and user management stay with the administrator.

Safeguards and alerts

Test-CNC connection check, FOCAS return-code logging, and optional SMS / WhatsApp alerts for CNC failure, idle folder or repeated NG parts.

In detail

Every part leaves a usable quality record: the part number, source file and receipt time; the nominal, tolerance, control limits and measured value; the raw and clamped correction with its direction and register; and whether the CNC write succeeded, was skipped or failed, with the FOCAS return details.

Benefits

What it delivers

Faster response to drift

The measurement triggers the configured correction without waiting for manual calculation and entry.

Fewer offset-entry mistakes

Direction, register, clamp and frequency come from the saved setup.

Same decision on every shift

Every operator gets the same configured response, and supervisors get a complete record.
