# Modular stone-CNC vacuum workholding pod assembly

## 1. Scope and Applicability

Manufacture by assembly of a new standalone modular two-level vacuum workholding pod for a stationary CNC stone machining table. The defined route receives individually finished top/base plates, structural and air-distribution posts, friction pad, upper/lower perimeter seals, interface O-rings, straight push-in fitting and separate ordinary/vented screws. It includes incoming geometry/identity inspection, conditional qualified local minor preparation, matched assembly/seal seating/torque, upper/lower vacuum-path and geometric acceptance, independent complete net weighing and dispatch. Actual drawing, compound/material, interface and included component configuration are declared for each pod; a source illustration does not identify material alloy or polymer chemistry.

Exclude complete stone CNC machines, general vacuum pumps/generators/manifolds/hoses, lifting/handling suction cups, whole clamping tables or sets, independently sold replacement seals/pads/repair kits, refurbishment and customer stone-cutting services. Bought complete-pod resale/testing-only, integral one-piece or other host/material architecture requires separate applicability. Plate/post machining, casting and finishing, pad/seal compounding/moulding/vulcanization and screw/fitting production are upstream supplied-part processes, not implicit local operations. External host, workpiece, table, pump, test fixture and packaging excluded from product M. Actual manufacturing test support and rework burdens included; no operating life, holding capacity, machining yield or full cradle-to-gate assertion.

Existing mineral-and-cold-glass-working-machine-tools covers complete hosts and expressly excludes separately sold components. Existing broad tool/work-holder methodology covers broad dedicated holders and offers reusable make/buy, normalization and acceptance controls; it is relevant prior methodology, not an absent record. This narrower modular stone-pod assembly case needs independent matched two-level seal protrusion/contact datum, solid versus vented screw and air-post circuit routing, installed pad/compound/supplier scope, table-side versus workpiece-side leak acceptance and frame-free standalone net M. General chuck/closed hydraulic expansion rules do not establish these interface facts. The new candidate is a bounded subroute refinement, not another universal work-holder PCR or code-only duplicate. Mapping/category placement between44251 workholders and44252 host-specific accessories is unresolved scientific review; no accepted mapping claimed. No other author unfrozen canonical content inspected.

| allocation_shared | shared test/preparation | For genuinely shared demand use measured causal machine/test time or metered load, disclose current original basis, denominator and sensitivity; economic basis only after documented physical causality unavailable. No flat ratio, rated capacity or universal scrap/recycling credit. |  |

## 8. Foreground Data Collection, Calculation, and Quality Rules

### Data Collection Protocols

| protocol_id | process_id | flow_role | record_type | raw_fields | collection_method | unit | frequency | temporal_coverage | site_scope | aggregation_rule | quality_evidence |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| cp_mass | dispatch | accepted complete output | measurement | model; configuration; serial number; accepted net mass M | Use traceable weighing records for the accepted complete unit of the same configuration. | kg | every accepted complete pod | matched manufacturing acceptance period | actual complete pod weighing station | accepted net mass per unit | whole fitted clean dry unit original calibrated readings/tare; independent installed-part mass closure; no table/pump/workpiece/test plate/packaging |
| cp_prepare | prepare | independent atomic exchanges | foreground_record | part/drawing/grade/compound/supply state; independent kg issues returns stock; individual circuit/torque/height/test results; meter/sampling readings and time; same-configuration accepted count | Record each actual exchange separately with supplier part and issue/return/stock kg, calibrated utility meters, original post-control species sampling/exhaust/time only when actual. Preserve drawing/compound/height/connection configuration, work orders, matched accepted units, rejects/rework/support and waste destination. | kg; MJ | per unit/test and full period | same-configuration manufacturing/acceptance cycle | actual assembly/test site and declared supplied-part gates | attributable process exchange / accepted units | supplied component content/material and calibration/test uncertainty; stock and accepted count closure |
| cp_assembly | assembly | independent atomic exchanges | foreground_record | part/drawing/grade/compound/supply state; independent kg issues returns stock; individual circuit/torque/height/test results; meter/sampling readings and time; same-configuration accepted count | Record each actual exchange separately with supplier part and issue/return/stock kg, calibrated utility meters, original post-control species sampling/exhaust/time only when actual. Preserve drawing/compound/height/connection configuration, work orders, matched accepted units, rejects/rework/support and waste destination. | kg; MJ | per unit/test and full period | same-configuration manufacturing/acceptance cycle | actual assembly/test site and declared supplied-part gates | attributable process exchange / accepted units | supplied component content/material and calibration/test uncertainty; stock and accepted count closure |
| cp_acceptance | acceptance | independent atomic exchanges | foreground_record | part/drawing/grade/compound/supply state; independent kg issues returns stock; individual circuit/torque/height/test results; meter/sampling readings and time; same-configuration accepted count | Record each actual exchange separately with supplier part and issue/return/stock kg, calibrated utility meters, original post-control species sampling/exhaust/time only when actual. Preserve drawing/compound/height/connection configuration, work orders, matched accepted units, rejects/rework/support and waste destination. | kg; MJ | per unit/test and full period | same-configuration manufacturing/acceptance cycle | actual assembly/test site and declared supplied-part gates | attributable process exchange / accepted units | supplied component content/material and calibration/test uncertainty; stock and accepted count closure |
| cp_dispatch | dispatch | independent atomic exchanges | foreground_record | part/drawing/grade/compound/supply state; independent kg issues returns stock; individual circuit/torque/height/test results; meter/sampling readings and time; same-configuration accepted count | Record each actual exchange separately with supplier part and issue/return/stock kg, calibrated utility meters, original post-control species sampling/exhaust/time only when actual.

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| normalize_mass | base_plate; top_plate; support_post; air_post; prepare_power; wash_water; wash_effluent; particle_air; pad; top_seal; bottom_seal; post_oring; straight_fitting; lower_screw; lower_vent_screw; upper_screw; upper_vent_screw; assembly_power; acceptance_power; dispatch_power; film | q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |

q_item is actual attributed exchange after issue/return/stock/rework balances divided by complete accepted same-configuration pod count. M comes independently from the same fitted net configuration. Preserve kg or MJ numerator; purchased finished part masses measured independently, counts supplementary. A count/area/volume identity is not automatically unsuitable, but conversion requires original same-part physical measurement and uncertainty; never rewrite its public property to Mass. No capacity/load/catalog shipping mass or invented unit weight.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| quality_mass | finished_machine | Original same-configuration whole pod weighing with all installed specified plates/posts/pad/seals/O-rings/fitting/screws and any retained adhesive. Use calibrated suitable-capacity balance, controlled fixture tare, date/serial/configuration/repeats/uncertainty. Exclude host/table/pump/manifold/hoses/workpiece/test plate/temporary fixtures/packaging and loose spares. Independently sum actual installed supplied part masses and actual retained additions versus M; count/ship mass/catalog dimensions cannot replace physical originals. | actual complete-unit weighing, supplier/part independent mass balance |
| quality_geometry | prepare; acceptance | Current approved matched plate/post heights, assembly datum, top/base contact parallelism and flatness, pad seating/friction-surface cleanliness and sealed perimeter geometry. Preserve actual drawing acceptance criterion and measured readings; one historical square200x200 anatomy and current round page are different products. Advertised+0.05/-0.00 tolerance is manufacturer case only, not universal pass criterion. | anatomy-pod-method; about-pod-method; current drawing/metrology originals |
| quality_seal | assembly; acceptance | Trace individual actual pad, top/bottom seal and interface O-ring material/compound/lot/profile, compression/protrusion/seating and compatibility with declared table/workpiece and cleaning media. Do not infer NBR/PU/silicone from colour or hard-rubber class from generic seal. Bought finished seals upstream, actual adhesive/grease/cleaner additions separately identified and counted once. Damaged/incorrect seats/rework documented; service notice supports checking seal/fitting condition but supplies no factory hardness/pressure threshold. | anatomy-pod-method; ghost-pod-method; actual supplier compound/assembly records |
| quality_circuit | assembly; acceptance | Verify original air-post ports and supplied fitting type/thread/tube OD/internal included seal. Distinguish top and base ordinary/vented screws; bore/torque/restriction cannot be collapsed into generic screws. Independently test every declared table-side/workpiece-side path, vacuum isolation and leak/hold performance at original plan pressure/time/limit with calibrated gauges and validated rig blank leak. Record actual support energy/test plate reuse; no lifting safety or stone-cut throughput claim. | anatomy-pod-method; ghost-pod-method; original current circuit/leak/torque tests |
| quality_identity | all flows | Public44252 finished parts and44251 workholders are relevant broad category candidates, not exact supplied modular pod proof. Classification placement reviewed independently from chemical/form/state applicability. Sealing-elements vulcanized/hard-rubber class does not prove actual specified compound; Steel screw does not prove source-specific grade/coating/vent state. Preserve actual property/unit chain; do not adopt component set/complete pump or vacuum service as one physical part. | public originals/property-unit chain and actual supplier qualification |
| quality_emission | particle_air | Only actual documented conditional dry touch-up post-control unspecified-size particulate to immediate unspecified air. No emission inferred from inspection/assembly/wet cleaning; captured debris, aqueous contamination and any measured size/species each separate correctly identified waste/elementary medium. Municipal water is technosphere product, not freshwater resource or wastewater; background electricity emissions not local air. | actual post-control sampling and liquid/solid waste records |
| quality_complete | dataset | Close actual supplier BOM/issues/returns/stock and accepted count. Add any real separate adhesive, grease, cleaner formulation, wiping cloth, rejected part/material, spent liquid, captured debris, test coupon consumed and each packaging material when present; every row one actual physical part or chemical/media species. No pooled materials/waste, assumed quantity, solder/casting/rubber cure at assembly factory, or claimed complete upstream coverage. Scientific review pending; actual factory dataset originals required before use. | actual complete stock/BOM/meter/test closure |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| validation_reference | finished_machine | Exactly1kg accepted complete fitted pod output, precise reference name equals finished_machine. Candidate UUID gap registered under exact row_id. Require original cp_mass actual M and independent fitted-part closure; formula/schema pass is not scientific approval. |  |
| validation_basis | inventory | Stable lowercase row/rule/protocol references, actual kg/MJ numerator, same-configuration accepted count and independent M agree in both languages. No host/set/test plate mixed denominator or catalogue/net mass confusion. |  |
| validation_scope | dataset | New independently supplied two-level stone-pod assembly with original pad/seal/circuit/datum acceptance; whole host, bought finished-pod resale, lifting cup and repair service excluded. Exact category/method overlap review remains open, not an accepted mapping. |  |
| validation_atomic | all flows | One physical specified part or chemical/medium per row. Exact official Chinese UUID name and actual reference property/unit retained; gaps explicit, measured emissions conditional. |  |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | foreground_manufacturing_module |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | Manufacture by assembly of a new standalone modular two-level vacuum workholding pod for a stationary CNC stone machining table. The defined route receives individually finished top/base plates, structural and air-distribution posts, friction pad, upper/lower perimeter seals, interface O-rings, straight push-in fitting and separate ordinary/vented screws. It includes incoming geometry/identity inspection, conditional qualified local minor preparation, matched assembly/seal seating/torque, upper/lower vacuum-path and geometric acceptance, independent complete net weighing and dispatch. Actual drawing, compound/material, interface and included component configuration are declared for each pod; a source illustration does not identify material alloy or polymer chemistry. |
| excluded_use | Exclude complete stone CNC machines, general vacuum pumps/generators/manifolds/hoses, lifting/handling suction cups, whole clamping tables or sets, independently sold replacement seals/pads/repair kits, refurbishment and customer stone-cutting services. Bought complete-pod resale/testing-only, integral one-piece or other host/material architecture requires separate applicability. Plate/post machining, casting and finishing, pad/seal compounding/moulding/vulcanization and screw/fitting production are upstream supplied-part processes, not implicit local operations. External host, workpiece, table, pump, test fixture and packaging excluded from product M. Actual manufacturing test support and rework burdens included; no operating life, holding capacity, machining yield or full cradle-to-gate assertion. |
| required_metadata | pod model/serial/drawing revision/shape/height; designated stone-CNC table interface and workpiece contact datum; top/base/post/air-post actual supplied geometry/grade/coating; pad and each seal compound/hardness/profile and supplier lot; actual connector tube/thread/gasket inclusion; separate solid/vented screws and torque/vent routing; actual upper/lower cavity connectivity and leak test rig, vacuum/hold time/instrument criteria from current plan; whole fitted clean dry pod original net M kg and independent part-mass closure; period/site/accepted same-configuration count/rework/support allocation; supplier gates and unresolved flow/upstream/classification gaps |
| required_quality_disclosure | Candidate scientific review pending; actual matched supplied component material/compound/gates, geometry/dual-side circuit original acceptance, net M/uncertainty/independent mass closure, site/period/accepted count and support/rework attribution, all missing IDs/upstream/transport/treatment and unresolved category placement. Per-kg accessory assembly not comparable holding service or full cradle-to-gate. |
| update_trigger | Part supplier/material/compound/interface, pad/seal/vent routing, height/datum/test plan, configuration/make-buy gate/site/period, new flow identities/source evidence or classification review outcome. |
