Rounds Chamfers Drafts Shells Ribs CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Rounds a Things to Remember: • Create rounds last if possible • Create smaller rounds before larger rounds • Avoid using round geometry as ref’s for other features • Drafted surfaces must be drafted before rounded CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Rounds a Round­Radius Options: • • • • • CONSTANT – created with a constant radius VARIABLE – radius value varies from one end to the other THROUGH CURVE – radius defined from a selected datum curve FULL ROUND – creates a round in place of a selected surface ADVANCED ROUNDS – intersection of round sets CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Chamfers a Edge Chamfers • Creates a beveled surface along a selected edge a Corner Chamfer • Creates a beveled surface at the intersection of 3 edges • No icon on toolbar for this – “Edit, Insert, Corner Chamfer” CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Chamfers a Edge Chamfer Dimensioning Schemes • 45 x d creates chamfer with a 45 degree angle and with a user­specified distance • d x d creates chamfer at a user­specified distance from an edge • d1 x d2 creates chamfer at 2 specified distances from an edge • Ang x d creates chamfer at a user­specified distance from an edge and at a user­defined angle CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Drafts a Drafts • Often used for cast and molded parts for ease of removal from the mold. • Maximum draft angle is +/­ 30 degrees CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Drafts a Neutral Plane Drafts • No Split – select draft surface, draft hinge, enter angle • Split at Draft Hinge • Split by Split Object CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Drafts a Neutral Curve Drafts • No Split • Split at Draft Hinge • Split by Split Object CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Shells a Shell Command • Removes a selected surface from a part and hollows the part with a user­ defined wall thickness • Wildfire allows for multiple wall thicknesses for one shell feature • Usually add rounds before using Shell command CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t Ribs a Rib Command • A thin web feature between features on a part • Can be revolved or straight • Similar to a protrusion that is extruded in both directions from a sketching plane CIMT 311 – Computer-Aided Design in Manufacturing CIMT 311 – Computer-Aided Design in Manufacturing FEATURE CONSTRUCTION TOOLS – Con’t a DEMO CIMT 311 – Computer-Aided Design in Manufacturing ...
