Checklist for Design Considerations
Workpiece:
- Size (large, small)
- Shape (rectangular, square, cylindrical, spherical, other)
- Required Accuracy (tolerances, machining allowances)
- Material Type (steel, stainless steel, aluminum, iron, other)
- Material Condition (cold rolled, hot rolled, cast, forged, other)
- Locating Points (machined surfaces, unmachined surfaces, holes, slots, other)
- Locating Stability (rigid, fragile)
- Clamping Surfaces (machined vs. unmachined, supported vs. unsupported, avoiding part damage)
- Production Quantity (limited vs. mass production, one-time vs. recurring production, projected future increases)
- Pending Part-Design Revisions
Operations:
- Type of Operations (machining, assembly, other)
- Number of Operations (similar vs. different, sequential vs. simultaneous)
- Sequence (primary operations, secondary operations, heat treating, finishing)
- Inspection Requirements
Equipment:
- Machine Tools (horsepower, size limitations, weight limitations, other)
- Cutting Tools
- Special Machinery
- Assembly Equipment and Tools
- Inspection Equipment and Tools
- Equipment Availability and Scheduling
- Plant Space Required
Personnel:
- Safety Equipment (machine, operator, plant)
- Safety Regulations and Work Rules
- Economy of Motion
- Operator Fatigue
- Power Equipment
- Possible Automation
