Build Inspection Into the Manufacturing Route
A result is useful only when the functional requirement and the evidence used to accept it are aligned.
A result is useful only when the functional requirement and the evidence used to accept it are aligned.
- ✓Functional datumsRelate the spline to bearing seats, journals, shoulders and mating bores.
- ✓Tooth-form controlVerify effective geometry with the agreed analytical or functional method.
- ✓Thermal stabilityPlan heat-treatment allowance, straightening and final finishing.
- ✓Fit evidenceUse master or mating gauges when the interface requires functional proof.
06 / DESIGN FOR MANUFACTURING
Design Decisions That Improve Process Stability
Resolve access, datum and inspection questions before manufacturing release.
Use a complete callout
Modeled teeth alone do not define fit, class or inspection.
Provide cutter runout
Shoulder and blind-bottom clearance affect route feasibility.
Define centering
State flank, major-diameter or other centering requirements.
Share the mating part
Interface context helps resolve fit and gauge decisions.
07 / PART APPLICATIONS
Where This Capability Creates Value
Manufacturing routes are adapted to the functional geometry and program stage.
01 / ROUTE
Splined Shafts
Drive shafts and actuators related to journals and bearing seats.
02 / ROUTE
Hubs & Couplings
Internal splines for torque transfer and serviceable assembly.
