What a prototype should prove
A prototype programme may be used to validate geometry, packaging, backlash, contact behaviour, material choice, heat treatment, assembly and inspection strategy. The purpose should be defined before parts are made.

Production-representative manufacture
Where practical, development parts should use processes and datums representative of the intended production route. This makes measurement and assembly feedback more useful when the design is released.

Control design changes
Drawing and model revisions should remain synchronised when tooth data, material, mounting geometry or microgeometry changes. This is especially important for matched gear pairs and compound components.

Transition to repeat production
Once the design is stable, manufacturing documentation, tooling, inspection routines and agreed reporting can be retained to support subsequent batches.

Need help with a specific gear?
Send Ondrives the drawing, model or available gear data. For new designs, include the operating duty and mating-component information so the manufacturing route can be reviewed in context.
Prototype evidence that supports production release
A useful prototype programme proves the assumptions that matter for production: geometry, manufacturability, material/heat treatment response, inspection method, assembly and application performance.
Control the revision
Use a controlled drawing and model revision for each build. Record any concession, process change or geometry update so the approved prototype can be translated into repeatable production data.
Inspect the right characteristics
Measure the features that govern function, including gear profile/lead/pitch/runout where required, datums, bearing fits, centre distances, material condition and hardness.
Plan production early
Prototype-friendly methods should be reviewed against intended production quantity. Tooling, automation, heat treatment, workholding and inspection time can change the optimum process for repeat manufacture.
Where the component is safety-critical or destined for aerospace, defence, medical, lifting or personnel-protection use, define the required approvals, traceability and verification at the start rather than adding them after the prototype is complete.
