Precision Machining

Precision machining and assembly
smart factory

High-mix machining changes jobs often, while drawing revisions, measurements and material lots tend to sit in separate places. Work orders provide the key that joins CNC state, floor results, gauge readings and barcode history.

Implementation sequence

  1. Progress is visible only on the floor

    Office staff cannot see how far a job has progressed, so every delivery question becomes a call to the floor.

  2. Measurements stay on paper and spreadsheets

    Gauge and CMM results are not bound to the work order or serial, delaying nonconformance investigation.

  3. Similar material and work in progress get mixed

    Manual issue, return and process-move records make similar stock and semi-finished parts easy to confuse.

Field issue

Every CNC and gauge speaks differently

Protocols vary by vendor and age, leaving per-machine screens instead of one view of the plant.

What gets connected

Machine signals and floor entry combined into history.

Build sequence

Nothing is converted all at once. High-impact areas are built and verified first.

  1. STEP 01

    Set work-order and identification rules

    Define how item, operation, drawing revision and material lot are bound before collecting signals.

  2. STEP 02

    Place floor kiosks and barcodes

    Start, pause, complete, issue and return are handled beside the machine with minimum input.

  3. STEP 03

    Standardise CNC and gauge data

    Machine signals and measurement files are converted to common tags and aligned to the work order timeline.

  4. STEP 04

    Connect quality and inventory, then expand

    Validate progress, tolerance exceptions and WIP flow first, then widen to more machines and operations.

Applied solutions

Scope is composed after reviewing equipment and workflow.

Production and routing

U-MES

Manages work orders, operation routing, results and material movement as one flow.

Measurement and quality

U-QMS

Connects readings, tolerance verdicts, nonconformance and reinspection by serial.

Machine data integration

Resource Lake

Standardises differing CNC and gauge formats into a common data structure.

Floor kiosks

UBoard

Shows work orders, next operations, machine state and delivery progress on the floor.

Related case studies

Each case states its disclosure scope and the basis for its figures.

Case study

Real-time work progress with shop-floor kiosks

A precision-machining floor entered results and checked next operations at the point of work for live progress.

Case study

Barcode and printer integrated inventory and BOM control

Barcode and BOM links from receipt to shipment prevented mis-issue and raised inventory accuracy.

Quick Answers

Precision machining and assembly — frequently asked

Questions that come up on precision machining and assembly floors.

Can older CNC machines provide data?

Available signals are surveyed first. Where no protocol exists, run and alarm contacts or external sensors can be combined with minimal kiosk entry.

Must every machining operation be digitised at once?

No. Start with a bottleneck or the machines most often checked for delivery, verify the link, then expand.

Can gauge readings be collected automatically?

Yes where the instrument exposes RS-232, file or network output. A minimal entry screen covers instruments without output.

Does barcode scanning add operator burden?

It is designed to replace duplicate entry. One work-order scan can carry item, operation and material context forward.

Can we keep existing ERP items and work orders?

Yes. ERP can remain the master while MES receives orders and returns floor results and material usage.
