Mechanical Design Knowledge

Practical machine-design guidance covering mechanisms, load calculations, tolerances, GD&T, shafts, bearings, guides, jigs, CAD, and release-ready drawings.

Machine Design #76: Machine Decommissioning — End of Life Must Be Designed Too
Machine Design #86: Standard Material Names — One Material Should Not Have Five Names
Machine Design #88: Machine Labels — A Small Plate Carries the Equipment Lifecycle
Machine Design #89: Part Marking — Identify It Without Weakening the Product
Machine Design #90: Matched Machining — When Two Parts Are Accurate Only If Made Together
Machine Design #81: Center Holes on Shafts — A Small Feature That Decides Rework Capability
Machine Design #82: Drawing Scale and Layout — Fast Reading Is a Technical Requirement
Machine Design #63: Heat Treatment and Hardness — Do Not Stop at One HRC Number
Machine Design #85: Standard Part Names — Name It So It Can Be Found, Bought, and Serviced
Machine Design #65: Conveyors and Drive Belts — Calculate the Force, Then Design the Whole Path
Machine Design #87: Directional Materials — Face, Back, and Grain Must Follow the Part
Machine Design #93: Draft Angle for Plastic Parts — Easy Release Must Preserve Function
Machine Design #91: Matched-Set Parts — Do Not Replace Half of the Accuracy
Machine Design #96: Inserts in Plastic Parts — Design the Small Joint for Heat and Force
Machine Design #95: Plastic Ribs and Bosses — Add Stiffness Without Creating Sink Marks
Machine Design #68: Safety Covers — More Than a Panel Around the Machine
Machine Design #70: Cable Carriers — Do Not Treat Electrical Cables Like a Decorative Chain
Machine Design #99: Position Tolerance for Hole Patterns — Control Replaceable Assembly, Not Each Coordinate
