# Handheld electric power tool manufacturing

## 1. Scope and Applicability

Manufacture of complete general workshop/construction tools designed to be held during work and containing their own electric motor: drills/drivers, impact tools, portable saws, grinders and sanders. Declare one product function and motor/drive configuration per dataset. Corded products include their installed mains cord; cordless products use a declared bare-tool-body supply without detachable battery and charger. Integral non-removable battery tools are outside this bounded body-only rule.

Exclude pneumatic/hydraulic/non-electric tools, stationary machine tools, garden/forestry machinery, medical/food appliances, separately sold parts, detachable batteries/chargers, interchangeable bits/blades/abrasives, kit cases, customer operation and maintenance, workpiece production and end-of-life. A kit must split its independent products and shared packaging using measured foreground attribution; it cannot use total kit mass as tool M. No machining, drilling or fastening service reference is defined.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | pcr.metal-products-machinery-and-equipment.special-purpose-machinery.handheld-electric-power-tools |
| classification_refs | CPC 3.0 44232; narrower tool-body manufacturing context; no accepted mapping |
| covered_products | Complete corded tool or cordless bare body with integral electric motor, configured by one working function. |
| excluded_products | Detachable battery/charger, integral-battery tools, consumables, cases, stationary/non-electric tools, garden/medical/food machinery and work services. |
| representative_product | One accepted cordless drill/driver bare body with declared motor, gearbox, chuck, switches and battery-contact interface. Corded variants include their actual power cord. |
| production_route | Received stock/parts → conditional polymer molding, drive-part machining, motor winding and electrical connections → configured assembly → factory acceptance/rework → dispatch. |
| market_state | New accepted complete declared tool body with retained lubricant and required guards/handles; independent kit products and shipping packaging excluded from net tool mass. |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Manufacturing delivery of a complete declared handheld electric tool body; it is a product reference, not energy-to-work efficiency or a customer working service. |
| How much | 1 kg of accepted net complete tool of one specified configuration; a normalized fraction of a whole tool, not an independently functional 1 kg component. |
| How well | Meets released BOM/drawings and actual acceptance criteria for fitted motor/drive, output interface, controls, guards, electrical conformity and specified working mode. No universal torque/speed/noise/durability or lifetime assumed. |
| How long or cycle | One manufacturing and acceptance cycle; tool operating hours, holes cut and fasteners driven are not this manufacturing denominator. |
| reference_flow_link | `finished_machine` |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Electromechanical tools for working in the hand, with self-contained electric motor `e7c50d40-dc9e-4e25-88d5-3df54c86969f` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | model/revision; serial/batch; working function; corded/cordless bare-body supply; brushed/brushless and AC/DC motor; gearbox/output interface; controls; rated voltage; required installed guards/handles; retained lubricant; installed cord/contact boundary; excluded detachable battery/charger/consumables/case; measured net M; actual release test criteria; factory/period; make-or-buy; molding/machining/winding/electrical routes; upstream/provider coverage; packaging exclusion |

Declare all qualifiers in dataset metadata/reference-flow comments. The broad public category is narrowed by this body-only scope and actual configuration; different working functions are not made equivalent by mass normalization.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_mass | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | M = accepted net mass of one complete machine of the same configuration in kg; collect using cp_mass. |
| electricity_units | molding_power; fabrication_power; motor_build_power; electrical_power; assembly_power; test_power | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Convert measured kWh using 3.6 MJ/kWh before normalization. Meter factory wall-side delivered supply, not rated motor power multiplied by an assumed test duration. |

Measure net M for the exact accepted corded tool or cordless bare body. Include fitted cord, contact interface, required handles/guards and retained grease; exclude detachable battery/charger, interchangeable consumables, case, workpieces and packaging. Use calibrated actual weighing and component boundaries; no category-average tool or battery mass is supplied.

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Purchased stock and finished parts received at one manufacturing site; supplier production not automatically foreground-covered. |
| starting_condition_role | Declared material/assembly starting point for a tool manufacturing module. |
| product_classification_scope | Dedicated general-purpose handheld electric tool body; excludes independent batteries/chargers and specialist garden/medical/food equipment. |
| recursive_input_rule | Purchased motor/gearbox/board/housing assemblies carry explicit included-part and upstream boundaries. Stop tracing at their declared supply and do not duplicate their internal resin, winding, bearings or grease. |
| upstream_dataset_requirement | Expanded studies separately link actual compatible suppliers, transport and waste treatment with technology, grade and geography disclosed; missing providers remain gaps. |
| disclosure | Report site/period, make-or-buy, outsourcing, assembly/test supply, shared kit packaging, capital/test-bench treatment, transport/waste coverage and omissions. The manufacturing module alone does not establish complete cradle-to-gate coverage. |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| boundary_foreground | manufacturing | Include actual receipt-to-release work, attributable utilities, consumables, losses, rework and tests. Conditional fabrication applies only where site work orders establish it; purchased finished parts replace duplicate site manufacture. |  |
| boundary_supply | complete_tool | Match released body supply, cord/contact interface, motor/drive/control and required safety fittings. Bosch and Makita model examples distinguish detachable accessories and corded/cordless controls; they impose no universal tool mass or manufacturing test. | bosch-drill; makita-hp1640 |
| boundary_downstream | customer_work | Exclude customer tool energy, battery cycling, replacement consumables and workpiece impacts. Include only actual factory load-test media and bench energy; do not import customer dust/noise values as manufacturing emissions. |  |
| boundary_species | elementary_flows | Quantify actual post-control species and outdoor receiving medium. Collected swarf/wipes are waste, not air emissions; purchased solvent is not an elementary emission identity. Unknown amounts remain gaps, not zero. |  |

Reconcile exact housing, motor/rotor/winding, gear train/output spindle, bearings, chuck or other fixed interface, switch/controller, cord/contact, guard, handle, screws and lubricant to the tool BOM. Each function needs its own actual interface/guard parts; this starting set is not a universal drill BOM for every saw or grinder. Add each missing physical part, chemical, waste and measured species separately. Site-built internal transfers are not purchased inputs; bought-in assemblies replace their contained raw materials and processes.

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| allocation_direct | manufacturing | Use direct work-order issues and meters first. Under cp_allocation, partition remaining shared demand by a measured causal driver: molding batch demand and shot mass/cycle; machining/winding machine time with measured power; assembly/test bench demand and actual station time; kit packaging measured product demand or geometric fit. Demonstrate the driver with foreground records and reconcile allocated plus excluded demand to the original total. No assumed fixed burden share. |  |
| allocation_variants | product_mix | Do not allocate all production by machine count when variants have different energy demand or configurations. A fallback mass or economic basis needs documented foreground justification, sensitivity and review; it is not a default imposed by this PCR. |  |
| allocation_scrap | steel_offcuts | Keep virgin/material inputs and separately measured scrap outputs without an automatic avoided-steel credit. Report scrap price and destination when relevant; any co-product classification or recycling credit requires a separately declared reviewed model to prevent double credit. Clean polymer regrind recirculated internally is not a saleable co-product. |  |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| normalize_mass | abs_resin; pa6_gf30; molding_power; abs_trim; steel_blank; al_cast_housing; fabrication_power; steel_offcuts; al_swarf; machining_pm; winding_wire; stator_stack; winding_varnish; motor_build_power; winding_offcuts; solder_wire; rosin_flux; ipa_cleaner; electrical_power; spent_wipes; ipa_air; motor; housing; gearbox; chuck; bearing; switch; controller; cord; contact; brush; grease; assembly_power; test_power; test_coupon; test_swarf; film; board | q_ref = q_item / M; q_item = exchange amount per one accepted finished machine; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |

Before applying normalize_mass, retain one declared configuration and matched period. Derive each q_item from its protocol: net stock/part issues minus valid returns, attributable meter use or measured waste/emission divided by accepted machine count for that same configuration. Include rejects and rework in manufacturing burdens carried by accepted output; never divide by all starts. Mass-weight datasets with different measured M values only after keeping configuration-specific records. Unit conversion and allocation are performed on raw records and retained as separate calculation evidence; no universal consumption range, density or emissions factor is supplied.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| quality_identity | all_flows | Match actual part/material grade, supplied state, concentration, geography, reference property and units. A UUID is identity only, not amount evidence or a provider dataset. Resolve blanks before treating an exchange as fully linked. | supplier sheet; flow/property/unit records; identity review |
| quality_completeness | complete_machine | Reconcile all configured BOM components, required fitted guards/handles and cord/contact to M; inventory actual utilities, chemicals, each waste and emission. Measure missing parts rather than infer them as the residual of M. Report coverage and any unlinked provider. | BOM revision; weigh sheets; material balances; missing-data register |
| quality_period | production_records | Use one declared factory and complete representative period; record model changes, seasonality, idle demand, outsourcing and rework; quantify primary coverage and uncertainty. Historic product cases cannot substitute for current production records. | work orders; acceptance ledger; meter calibration; source limits |
| quality_test | acceptance | Use current released criteria for the actual motor/drive/control/output interface, required guards/handles and electrical conformity. Distinguish corded and cordless bench supply. Manufacturer user performance/safety advice is not a universal factory test limit or durability requirement. | signed test plan; serial/model results; calibration and conformity specification |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| validation_reference | finished_machine | Require 1 kg reference output, cp_mass measured M, complete declared tool-body supply and installed cord/contact/guards/handles/grease boundary. Detachable battery/charger, consumables, case and packaging must not enter M; do not use kit gross mass. |  |
| validation_normalization | inventory | Every applicable non-reference row uses normalize_mass and a declared protocol; check q_item and M share configuration/period, correct division direction and preserved energy/volume/item numerator units. |  |
| validation_route | processes | Match site molding, gear machining, motor winding and electrical work to actual make-or-buy records; no duplication of resin and housing, wire and bought-in motor, bearings/grease and bought-in gearbox, or reusable bench battery and shipped tool. |  |
| validation_species | elementary_flows | Match isopropanol CAS67-63-0 and outdoor-air unspecified subcompartment, particulate particle-size coverage and post-control boundary. Indoor or upper-troposphere isopropanol identities do not match outdoor factory emissions; captured swarf/wipes remain waste. No emitted fraction or emissions factor presumed. |  |
| validation_coverage | dataset | Disclose measured, calculated, estimated, excluded, not-applicable and missing quantities distinctly; reconcile accepted outputs, scrap, stock and allocation closure. A method check or valid projection does not approve scientific methodology or establish cradle-to-gate completeness. |  |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | foreground_manufacturing_module |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | A documented manufacturing module for the exact configured machine and period; upstream-connected assessment only after supplier/transport/treatment coverage is established. |
| excluded_use | Customer machining/fastening services, operating-energy or lifetime comparisons, lifespan-normalized claims, generic equivalence between appliance configurations, and unsupported complete cradle-to-gate claims. |
| required_metadata | PCR id; model/configuration/BOM and serial scope; measured M and declared battery/cord/grease boundary; acceptance standard; site/period; make-or-buy and process route; reference basis; providers and transport; packaging; allocation; data sources; version. |
| required_quality_disclosure | Measured coverage, missing identities/providers and quantities, route exclusions, source age/limits, conversion conditions, allocation evidence, emissions monitoring gaps, uncertainty and independent review status. |
| update_trigger | BOM or configuration change; revised acceptance test; changed supplier/process/electrical or energy supply; new representative production period; resolved identity or evidence gap. |
