If you are evaluating an Ermaksan FIBERTUBE Tube & Profile Laser Cutting purchase, treat it as two separate due-diligence tracks. Operational readiness determines whether you can sustain throughput through changeovers, nesting/remnant handling, fault recovery, and maintenance cadence. Safety documentation readiness determines whether your organization can complete its laser hazard assessment and eye/face protection program using documentation that aligns with OSHA expectations and ANSI Z136.1 program concepts.
Use this procurement checklist to gate both tracks before installation, so your RFQ and PO demand proof, not just positioning.
Track 1 automation diligence: Ermaksan FIBERTUBE automation/process-control readiness for uptime
On the operational side, I am not just asking whether the system has “automation.” I translate each published function into the questions your team must answer during setup, run, fault recovery, and routine maintenance. The goal is simple: turn feature promises into workflow changes you can validate during commissioning.
1) Vision and nesting automation: what changes in your operator workflow
- Automatic Nesting (camera-assisted): Ermaksan describes Automatic Nesting using part geometry data together with an image taken from the camera to reposition parts and generate corresponding NC code.
- Vision Auto Remnant: Ermaksan describes Vision Auto Remnant as camera-based detection and management of remnant sheets.
What you evaluate next is not “Is it automated?” but “Where do operator touches move to decision-making and exception handling when vision results are uncertain?”
Workflow questions to ask during evaluation:
- When you switch jobs or material thickness, how will you confirm the camera input is correct and the generated NC output matches your quality standard before full production time is committed?
- For mixed part families, where do you expect the biggest yield or scrap risks: incorrect part placement, remnant mis-detection, or downstream offsets caused by handling?
- If camera/vision inputs do not meet expectations, what is the fault recovery path (who decides, what steps are required, and how long the recovery takes in your commissioning test plan)?
2) Real-time NC graphics: how you will monitor, intervene, and reduce downtime
Ermaksan describes NC graphics and real-time streaming for live visibility into the cutting process using a visual interface. For the ECO configuration, Ermaksan describes a colored 2D NC graphic showing which line of code is being executed.
What you evaluate next:
- During commissioning, can your lead operator use these displays to identify the right problem quickly (for example, wrong code execution, a part placement mismatch, or a process irregularity)?
- Is the interface role-based and usable by the shift coverage you actually run (to avoid a hidden throughput constraint where only one person can interpret the graphics)?
- What criteria trigger intervention (at what point do you stop to avoid burning time on a likely scrap run, versus continuing to learn and validate)?
3) Operator guidance: ERAI AI Assistant and how it affects training time
Ermaksan describes ERAI as an AI assistant for guidance and troubleshooting intended to help operators get the most out of the laser machine.
I treat AI assistance as a training and fault-reduction support tool, not a substitute for process ownership. Ask for:
- A list of the common fault categories the assistant supports and the documented steps it recommends.
- Evidence the guidance aligns to how you actually run jobs, including your part numbering conventions, nesting conventions, and first-article checking approach.
- Operator training materials that connect ERAI recommendations to your internal work instructions so you do not end up with parallel, conflicting procedures.
4) Nozzle cleaning and calibration: how maintenance and downtime are actually managed
Ermaksan describes NOZZLE CLEANING / CALIBRATION as automatic cleaning and calibration intended to support consistent cutting quality and reduce downtime.
Diligence questions I require answers to:
- What triggers nozzle cleaning/calibration automatically, and what triggers it manually? Is it time-based, cut-count based, material/process-based, or condition-based?
- What maintenance intervals are expected for components tied to nozzle cleaning/calibration (consumables, sensors, or serviceable subassemblies)?
- What spare parts list do they recommend to keep nozzle cleaning/calibration routines from turning into a service stoppage, especially during early ramp?
- During commissioning, can you quantify the downtime impact of these routines under your materials and test settings?
5) Turn “features” into measurable acceptance criteria
Executives and procurement leaders typically reduce risk when the PO gates measurable acceptance criteria. Use these examples to map feature claims to your real KPIs without assuming automatic cost reductions:
- Changeover time delta: measure setup and first-article time when switching job parameters that affect vision inputs and NC generation.
- Yield and scrap drivers: track whether scrap comes from placement, remnant mis-detection, wrong NC output selection, or operator interpretation during intervention.
- Recovery time: measure time to resume after simulated vision input failure or a re-run scenario.
- Maintenance cadence: track how often nozzle cleaning/calibration occurs and whether it matches your shift staffing model and planned maintenance windows.
Track 2 safety documentation diligence: OSHA plus ANSI-aligned readiness before installation
On the safety side, documentation readiness should not be left to “we will figure it out later.” OSHA expects employers to assess laser hazards and implement controls as part of a laser safety program. OSHA’s laser safety and hazard assessment enforcement guidance describes how safety assessment and controls are organized, including controlled areas and administrative/procedural controls. OSHA’s eye and face protection standard then sets the employer obligations for eye/face protection when exposure hazards exist.
NIST frames laser safety program elements in a way consistent with ANSI Z136.1 program concepts (including identification of direct and ancillary hazards, engineering and administrative controls, PPE selection, control areas, signage, and training). The Laser Institute of America’s ANSI Z136.1 sample structure can help you define what “good documentation” looks like in procurement questions.
To make this practical for procurement, use the following PO-gated documentation request list.
PO and RFQ-ready documentation request list (checkboxes)
Before installation, ask the OEM to deliver a safety package your EHS lead can use to complete your employer hazard assessment and eye/face protection program. The key is documented support you can verify during commissioning, not marketing brochures.
- ☐ Laser hazard assessment support: OEM documentation describing direct and ancillary hazards for the installed configuration, including beam path and service-related hazards, consistent with OSHA hazard assessment expectations.
- ☐ Engineering and administrative controls overview: documentation that explains how controls are implemented on the machine (beam-path-related controls, controlled-area assumptions, and relevant administrative/procedural elements).
- ☐ Laser controlled area and access control documentation: what constitutes controlled access, what interlocks exist, how access is managed, and what procedures apply when doors/interlocks/access panels are used.
- ☐ Eye and face protection selection support: documented guidance that connects PPE selection to hazard assessment outputs (including wavelength-appropriate eyewear/face protection concepts) and supports your OSHA 1910.133 program decisions.
- ☐ Training and operating procedure support: operator and service training materials aligned to the program elements your laser safety program must cover, including practical procedures that match the installed configuration.
- ☐ ANSI Z136.1 program alignment indicators: a mapping or outline showing which program elements are supported by the OEM documentation, consistent with ANSI Z136.1-style organization (engineering controls, administrative controls, PPE considerations, user training, and refresher training concepts).
- ☐ Commissioning and acceptance verification steps: step-by-step checklist your team can use to verify interlocks, signage/controlled-area assumptions, and protective features during acceptance testing.
Eye and face protection: what I do not accept as a shortcut
OSHA’s eye and face protection standard places requirements on employers when employees are exposed to potentially injurious light radiation. I therefore do not accept generic statements like “appropriate eyewear is provided.” Instead, require documentation that supports your hazard assessment-driven PPE selection decisions and shows how PPE and protective procedures connect to the actual work and machine configuration.
Your organization still must complete the employer hazard assessment and train employees appropriately under OSHA requirements.
Use market context to validate the business case without overreaching
If you need baseline workforce and industry context for capex planning, the U.S. Bureau of Labor Statistics provides national context for fabricated metal product manufacturing (NAICS 332). Use it to frame planning assumptions, not to claim a local installation footprint.
My go/no-go gating logic: what I verify before funds are fully committed
To reduce capex delay risk and late-stage safety rework, I gate the purchase on both tracks.
Track 1 operational sign-off (automation readiness)
- You can run a first-article workflow that includes camera-based nesting or remnant detection without unclear operator decision points.
- You can demonstrate fault recovery for vision and intervention scenarios without turning troubleshooting into a multi-shift learning project.
- Your maintenance plan covers nozzle cleaning and calibration routines with defined responsibilities, expected intervals, and spares support.
Track 2 safety sign-off (documentation and readiness)
- You receive an OSHA plus ANSI Z136.1-aligned documentation package your EHS lead can use to complete your hazard assessment and laser safety program implementation.
- You can confirm eye/face protection selection support aligned with OSHA 1910.133 requirements.
- Acceptance testing includes verification of controls, and your commissioning checklist is executable on your floor in the final installed configuration.
What managers should evaluate next
If you want a quick next step, walk through these items with your purchasing manager and operations lead:
- List your top 3 job changeover drivers and ask how the FIBERTUBE workflow validates camera inputs and NC output correctness for each driver.
- Map your current nesting and remnant-handling touches to the automation features, then define which touches should disappear, and which operator checks must remain (with clear criteria) for exception handling.
- Demand a nozzle cleaning/calibration routine explanation that ties to your staffing model and commissioning acceptance criteria.
- Provide your EHS lead the PO-gated documentation request list for OSHA laser hazard assessment and eye/face protection readiness, and require OEM delivery before installation.
- Use your own material variability history to frame commissioning validation runs, focusing on where automation must be reliable and where it can introduce new failure points.
