Cam Mechanism Retrofit
Machine modification and validation of a cam-driven subsystem

Overview
Retrofit study for a cam-driven subsystem, focusing on mechanism layout, clearances, and validation against functional requirements.
Problem / Context
The machine needed a revised cam-driven mechanism to meet updated kinematic requirements while remaining manufacturable and serviceable.

Process
- - Documented functional requirements and constraints
- - Mapped kinematics and cam follower motion
- - Built detailed CAD assemblies and drawings
- - Checked clearances and manufacturability
- - Prepared validation and test checklist
Key design decisions
- - Prioritized simplified linkage geometry for manufacturability
- - Used sectional drawings to verify load paths and clearances
- - Kept interface points consistent with existing machine frame
Engineering details
- - Cam-follower kinematic layout and tolerance checks
- - Assembly drawing with bill of materials and references
- - Validation focused on motion smoothness and repeatability
Outcomes
- - Complete CAD drawing package for the retrofit
- - Validated kinematic envelope and integration feasibility

What I would do next
- - Prototype the cam profile and follower
- - Run endurance testing for wear and lubrication
- - Integrate sensor feedback for timing control
