Design Focus | Professional Guidelines |
---|
Dimensional Tolerancing | Apply tolerance stack-up analysis. Use ISO 286 IT7–IT9 fits for shafts, bushings, and guide profiles in motion-critical automation parts. |
|
Material Selection | Choose fatigue-resistant alloys (e.g., 42CrMo4, 7075-T6) or tribologically optimized polymers (e.g., PEEK, PTFE) based on load cycles, temperature, and sliding interfaces. |
|
Modular Assembly Interfaces | Standardize hole patterns (DIN 55101, ISO 9409-1) and use dowel-pinned datum references to enable quick integration with linear actuators, sensors, and robotic end-effectors. |
|
Electromechanical Integration | Provide embedded slots or M12 cutouts for sensor mounting and cable conduits. Ensure EMC shielding continuity at electrical interface zones for signal integrity. |
|
Dynamic Load Design | Validate structure under cyclic loading via FEA. Maintain safety factors ≥1.5 for 10⁶+ cycle life. Optimize rib geometry for stiffness-to-weight ratio in reciprocating mechanisms. |
|
Accessibility and Maintenance | Design components for single-direction service access. Include slotted fasteners, clear tool paths, and visual ID markings. Modularize assemblies for minimal machine downtime during part replacement. |
|
Thermal and Structural Stability | Use matched thermal expansion coefficients (CTE < 15 μm/m·K) between interfacing parts. Isolate heat sources with insulating sleeves or slots to prevent dimensional drift in linear guide systems. |
|
Noise and Vibration Management | Introduce elastomeric bushings or tuned mass dampers to suppress resonance. Conduct modal analysis for vibration-sensitive components mounted on servo stages or precision assemblies. |
|
Surface Engineering | Apply appropriate treatments—anodizing for corrosion resistance, hard chrome for wear reduction, or dry film lubricants for maintenance-free bearing surfaces under intermittent motion. |
|
Design for Assembly (DFA) | Limit fastener types and assembly tools. Incorporate alignment features and tolerance-compensating bushings for rapid fitment on automated production lines or robotic workcells. |
