An accepted quotation is not a machine command.

Sales, preparation and machine operation need separate decisions

A customer can accept a quotation while questions about the manufacturing process remain unresolved. Commercial acceptance concerns scope and delivery terms. Production preparation checks the documents and restrictions needed for subsequent work. Safe release of a specific machine is another step again. Merging these events is especially risky when revision, quantity or available material changes between quotation and production. A clear workflow preserves the boundaries.

KOVOSYS includes manual handover of an accepted quotation into production preparation. An administrator or estimator reviews the evidence, confirms preparation and explicitly approves it. Mail processing and automatic costing do not replace this action. The purpose is to save a particular approved basis, not suggest automatic workshop control. A prepared job remains a preparation record, not a verified CNC program or authorisation for an operator to start a laser without further checks.

Define who may approve work and what must be checked before confirmation. An application permission and professional responsibility are not the same thing. Access to a button does not demonstrate knowledge of customer tolerances, material behaviour or safety procedures. Make the process understandable to covering colleagues as well as the person who originally quoted the work.

Start with the accepted quotation and its actual scope

Identify which quotation the customer accepted and what specification it represents. A document number alone is insufficient if its contents changed. Compare revision, items, quantities, material and related drawings. The inquiry may contain newer working data that has not been commercially approved. Do not hand over a new shape at an old price while claiming to manufacture exactly the accepted offer.

Acceptance may be recorded in a message or another document recognised by company practice. This guide does not determine the legal effect of every acceptance method. What matters here is tracing what the customer confirmed and separating that evidence from an internal status label. A response containing a condition or change is not automatically simple acceptance of the original scope.

Resolve changed delivery dates, quantities and added surface treatment before preparation, because they can affect cost and method. Create the job from clear evidence rather than the most likely interpretation of several emails. A brief summary of confirmed items can be enough. The test is whether another worker can establish the valid scope without searching contradictory attachments or relying on an oral explanation.

Check quantities and revision together

Compare every line quantity with the customer requirement. Sets can contain several parts, and left and right versions may require different counts. Copies already drawn in a DXF must not be unknowingly multiplied again by the ordered quantity. An internal hole is not another delivered piece. Define what one part represents and how many copies its preparation layout must contain.

Check revision in geometry as well as description. A single changed hole can be functionally critical while overall width and height stay the same. Dimensional validation alone cannot recognise an old drawing with the same envelope. Compare the valid source and accompanying requirements. A post-acceptance change needs renewed commercial assessment and any required approval, not a silent replacement of an attachment under an old historical record.

A useful review lists name, revision, material, thickness, quantity and principal dimensions. Add surface direction or a rotation restriction for atypical work. Such a list assists independent checking but is not complete technical documentation. Tolerances and later operations may need information absent from the dimensional envelope. Equal envelopes do not demonstrate that parts are functionally interchangeable.

Material and thickness need explicit company rules

New approval requires explicitly configured company technology rules for the relevant material and thickness. Missing rules block handover; historical defaults are not evidence of suitability for a new company. An administrator must define permitted sheet formats, spacing, edge margins and rotations. These values describe the actual workplace. They cannot safely be inferred from a marketing diagram or a job completed at another workshop.

Match the material designation with the customer specification and the material that will actually be used. Equal thickness does not imply equal technology for different alloys or finishes. If the customer supplies the sheet, clarify dimensions, condition, identification and responsibility for suitability. The application does not automatically certify stock availability or material quality. It evaluates preparation using configured conditions whose factual suitability remains a human responsibility.

When rules change, decide which new jobs should use the new values and how earlier approvals will be assessed. The saved approval snapshot preserves selected technology rather than silently rewriting past decisions from current settings. That record explains what was approved at the time. It is not a recommendation to keep using a superseded rule or evidence that older conditions remain safe for a different job.

Part spacing and edge margin are different conditions

Spacing separates neighbouring dimensional envelopes; edge margin restricts the usable part of the sheet. Check them independently. A layout can have adequate inter-part distances while entering a forbidden edge region, or respect the edges while leaving too little separation between copies. No universal safe value is prescribed for every material, thickness and machine. Settings must follow the company's verified technology and subsequent professional review.

Current preparation validation uses rectangular envelopes derived from stored part dimensions. Envelope spacing is not a complete simulation of cutting paths, lead-ins or thermal effects. Additional room for clamps, handling or particular entry paths cannot automatically be guaranteed by a rectangle check. Account for these needs in company rules and downstream technological preparation. A tightly packed image must not override a safe working procedure.

Keep the same spacing and margins when comparing alternatives. Better filling achieved by reducing a safety distance is not proof of stronger optimisation. Approval concerns both the result and the conditions under which it was created. Resolve an unclear requirement before confirmation; it cannot be reconstructed later from a utilisation percentage or from the fact that the parts happened to fit.

Allowed sheet formats and rotations have production meaning

For a material and thickness, the company can define permitted formats and rotations in right-angle increments. This does not mean arbitrary-angle rotation or mirroring. Brushing, rolling direction, protective film and later bending may limit orientation. If the whole assembly needs a common surface direction, the approver must know it. A geometric fit after a quarter turn is not enough to justify using that orientation.

The layout chooses among deterministic candidates, not every mathematically possible arrangement. It is not claimed to be a global optimum. Preparation requires complete placement on one permitted sheet. If all required copies do not fit under the rules, a partial result must not appear approved. Automatic distribution of the entire order over several sheets is not presented as a finished feature of this workflow.

A permitted format does not prove the physical sheet is in stock or has the required condition. Verify availability and material identity through the company's established process before production use. A changed available format needs more than a price check: it can alter placement, margins and handling. Cases that do not fit require separate preparation with an explicit completeness check, rather than disabling the restriction to force approval.

What independent envelope validation can check

A separate validator checks part identities, copy counts, dimensions, overflow, overlaps, gaps and allowed rotations independently of the placement algorithm. The important question is whether the result contains precisely the expected copies, not whether the sheet looks full. Missing or duplicated parts invalidate a favourable utilisation figure. One overflowing copy cannot be excused by a correct total area: completeness and boundaries are separate conditions.

An envelope does not validate the original drawing shape. Different parts can share width and height but contain different holes or have different functional orientation. A spline may be misinterpreted without greatly changing its bounding size. An open contour can look closed. A qualified person must assess those points in the source. Approving dimensional placement is not certification of CAD geometry, CAM paths or physical manufacturability.

This preparation result does not place parts inside the holes of other parts or solve every technological opportunity for material efficiency. A conservative envelope arrangement can be understandable without being the best available nesting solution. In a commercial comparison, state whether the measure uses actual contours, envelopes, a charged rectangle or a whole sheet. These definitions matter as much as the reported numerical result.

Manual approval confirms a particular set of evidence

Before approval, review quotation revision, material, quantities, dimensions, rules and the placement preview. Confirmation is not administrative decoration. It records a deliberate decision about the preparation evidence within the scope of this step. Resolve contradictions first. Do not approve a job on the assumption that a technologist may later work out what the customer meant, leaving the preparation queue full of items that only appear ready.

The saved snapshot preserves quotation and revision, source fingerprint, material, quantities, dimensions, selected technology rules, placement, approver and time. Later editing of the inquiry does not overwrite that evidence. The queue can signal a changed source, showing that current inquiry data may differ from the approved basis. The company must still decide whether a change requires stopping work and renewed commercial or technological review.

Repeating the same request must not create duplicate production jobs. One quotation cannot create two jobs, even after cancellation of the first. Corrected scope requires the appropriate new quotation and fresh approval. Do not bypass that relationship by copying names or presenting amended requirements as the same already approved basis. Traceability depends on preserving what was actually decided, not only on keeping a familiar job label.

Preparation queue, completion and cancellation

Authorised roles read the preparation queue and export within their own company. Production users and administrators can mark preparation completed or cancelled; the workflow also permits cancellation after completion. Estimators approve and read, but are not thereby granted every status change. Changes preserve actor and time and require the current revision. Verify actual permissions using separate accounts, not only an administrator account that sees more controls.

Completed preparation means completion of the preparation step. It does not automatically mean a machine started, cutting finished or a safety release occurred. KOVOSYS is not presented here as a universal capacity planner or a record of every physical operation. Define suitable systems and rules for actual cutting progress, quality inspection, packing and dispatch if those are required. One preparation status cannot truthfully stand for all subsequent events.

Cancel an incorrectly prepared job and resolve its cause through the appropriate follow-up. If a hole or quantity changed, changing status alone does not update the original approved evidence. Corrected scope needs another assessment. History should explain decisions, not hide amendments under an unchanged title. Before repeating an action after a connection interruption, determine whether the original action already succeeded so the process remains commercially understandable.

A preparation export is not G-code or CNC control

The JSON export is a preparation package, not an NC program, G-code or a laser-controller instruction. Saved reference previews are not executable production documents either; the preparation interface displays numerical envelopes. The downstream technological workplace must create and verify paths, order, lead-ins and machine parameters in its designated environment. KOVOSYS does not replace CypCut, certify a machine's safety or authorise an operator to bypass established checks.

Run the first evaluation on a known job with clear drawings, confirmed quantities and configured material-thickness rules. Compare the commercial scope, preparation snapshot and information actually received by the technologist. Add a case with no suitable format and one with a missing rule. Both should lead to an understandable stop, not partial approval. Test a source change after approval so colleagues can distinguish historical evidence from the current inquiry.

When asking a technical question, give the step, user role, material, thickness, quantities and expected constraint. Do not send credentials or confidential drawings without agreement. The contact page identifies the operator and explains safe first contact. The DXF, costing and nesting guides complement input checks. Good preparation is the ability to show what was consciously approved and what still requires review, not a promise of unattended production.

Assess the impact of a change after approval

Imagine an accepted bracket quotation followed by a customer change to one hole. Overall dimensions stay the same, so the envelope layout may still look usable, but the manufacturing specification is different. Decide whether work stops, which documentation is valid and whether pricing changes. Matching envelopes are not a reason to treat the old approval as confirmation of the new shape. Both commercial and technological staff need to understand the difference.

A quantity change creates another kind of risk. Adding copies may exceed a single sheet, while removing an item may change the material charging basis. Do not merely amend a covering email while retaining the old preparation package. Reassess completeness and use the corresponding quotation and approval process. The historical snapshot should remain evidence of the original decision, not a flexible document that silently follows every later message.

After restoration or interrupted work, check the point in time represented by available data. A backup event is not customer consent to revert to an earlier revision. Compare approvals with correspondence retained under company policy before continuing. If continuity cannot be explained, do not hand over an old export as unconditionally ready. An informed stop is preferable to trusting whichever file happens to be available.

Use recurring changes to improve the process. Identify whether filenames, role handover or incomplete confirmation caused the problem. A vague instruction to check everything more carefully is not enough. Define a specific check, its owner and where its result is recorded. This keeps manual approval practical for repeat work without turning it into automatic confirmation of a familiar customer name.
