Shared Test Platform and Fixture Changeover Worksheet

Use this worksheet to decide whether multiple motors, robot joints, axes, or fixtures can share one controlled test platform. Hardware fit is only one condition; capacity, interfaces, measurement planes, software, safety, evidence, availability, and release status must also remain within the approved boundary.

Project and configuration identity

Project / platform	Configuration revision	Date
DUT variants / axes	Fixture / adapter IDs	Recipe IDs
Prepared by	Reviewed by	Release status

Share or separate decision

Decision dimension	Shared boundary to verify	Separate / redesign trigger
Capacity and duty	Torque, speed, power, inertia, travel, thermal state, duration, direction, quadrant, and utilities	Different loading technology, safety class, or sustained-energy boundary
Mechanical interface	Mounting, adapter, coupling, alignment, stiffness, load path, guarding, access, and cable motion	Unverified compliance, runout, resonance, preload, or service exposure
Measurement plane	Sensor location, range, reference plane, timing, calculations, tare, and uncertainty treatment	Materially different plane, range, reference, or measurement principle
Control and safety	Protocols, modes, limits, feedback, brake, fail-safe states, guards, interlocks, and stop behavior	Incompatible behavior cannot be isolated in the released configuration
Evidence and permissions	Recipe, channel map, raw data, report, access, release, override, export, and retention boundaries	Customer, project, IP, or approval boundaries cannot be separated
Availability	Changeover, stabilization, verification, maintenance, recovery, calibration downtime, and retest	Sharing creates an unacceptable queue, interruption, or restoration exposure

Variant capacity record

DUT / axis / fixture	Included components and interfaces	Operating and duty boundary	Measurements and safety state	Fixture / recipe / evidence IDs

Fixture-changeover release

Release check	Required record	Status / exception / evidence
Identity and revision	DUT, fixture, adapter, coupling, fastener, drawing, controller, software, and recipe revisions
Physical installation	Condition, locating features, installation sequence, fastener method, alignment, load path, and cable or hose routing
Protection and interfaces	Guards, interlocks, limits, brake, emergency stop, utilities, protocols, and safe-state behavior
Measurement configuration	Sensor ranges, channel map, reference planes, timing, zero, tare, reference, and verification checks
Controlled proving sequence	Approved low-risk sequence, expected response, exceptions, and stop criteria before the full test envelope
Release decision	Open items, authorization, effective configuration, permitted DUT and envelope, and required re-verification

Scope limit: This worksheet defines a review and release structure. It makes no universal claim for Weiheng platform capacity, changeover time, accuracy, availability, customer results, or project acceptance. Project values require approved records.
